PreliminarySKY899Installation Manual1-1Rev. ACHAPTER 1GENERAL INFORMATION1.1 INTRODUCTIONThis section contains a functional description of the BFGoodrich Avionics Systems SKY899 trafficalert/advisory system sensor, describes the various hardware and software configurations, outlines themain features of the system, and provides a system block diagram. The SKY899 is a new generation trafficalert/advisory system that has different inputs and outputs and it requires different wiring than theSKY497. Connector P1 is keyed differently to prevent connection to the wrong TRC.NOTES1. The SKY899 is designed to be installed as a TCAS I traffic alert system or as a TAStraffic advisory system. The system installation differences are as follows:• TCAS I installations requires an alternate display device (i.e., EFIS, MFD, IVSI, weatherradar indicator) FAA approved for displaying TCAS I information and the antenna must bean NY156 directional antenna.• TAS installations can have an alternate display device, the WX-1000/SKY497 display, orboth as the primary means displaying traffic information. Either the NY156 or NY164directional antenna can be used.2. Contact Field Service Engineering at 1-800-453-0288 or 1-616-949-6600 forapproved displays and software version requirements of the TRC899.3. The SKY899 does not track intruder aircraft approaching at a closure rate greaterthan 1200 knots.4. This section provides installation information for the SKY899 using the WX-1000/SKY497 Display. If using an alternate display device refer to manufacturerinstructions for installation details.5. When interfacing to a weather radar indicator via the BFGoodrich Avionics SystemsRGC250 (Radar Graphics Computer) refer to the RGC250 Installation Manual forinstallation instructions. RGC250 must have software version 1.5 or later.6. When an alternate display device is installed the service menu can not be accessedvia the display, therefore a terminal device (i.e., laptop) is required for system setupand post-installation checkout (refer to appendix E).7. When planning ARINC-429 receiver interfaces note that:• The equipment connected to receive channels 1 and 2 must be the same speed(12.5 or 100 kHz).• The equipment connected to receive channels 3 and 4 must be the same speed(12.5 or 100 kHz).• Channel 5 receiver is independent of the other receivers and can be set to 12.5 or 100 kHz.8. In order to use ADS-B SKYWATCH HP requires a GPS input that is GAMA or ARINC-743Acompliant.
PreliminarySKY899Installation Manual1-2Rev. A1.2 FUNCTIONAL DESCRIPTIONThe BFG Avionics Systems SKYWATCH® HP SKY899 is a new generation airborne traffic alert/advisorysystem that increases the active-mode surveillance range over the SKY497 system from 20 nmi to 35 nmiand adds Automatic Dependent Surveillance-Broadcast (ADS-B) surveillance mode. The SKY899continuously monitors the dedicated data link frequency (1090 MHz) for ADS-B mode S extended squittermessages within 50 nmi. The ADS-B message contains navigational information about the intruderaircraft including GPS position, ident, ground speed, and intent. The SKY899 uses this navigationalinformation along with its own aircraft GPS navigation data to calculate the relative position of theintruder to augment its active ATCRBS surveillance of the intruder. ADS-B surveillance enhances thetraffic alert/advisory abilities by increasing the accuracy of the active-mode surveillance. The SKY899 doesnot require a mode S transponder, ADS-B capable or otherwise to perform its ADS-B surveillance.The SKY899 advises the flight crew where to look for aircraft that may pose a collision threat. It isintended for use by corporate and general aviation aircraft. SKY899 alerts the flight crew to nearbytransponder equipped aircraft and assists the pilot in the visual acquisition of aircraft that may representa danger. Traffic information out to a selected range is graphically displayed on the display. Using shapes(i.e., Traffic Advisory = solid circle; Other Traffic = open diamond) and text, the display shows the relativeposition of threat aircraft.1.3 PHYSICAL DESCRIPTIONThe SKY899 System consists of the following main components:• Transmitter Receiver Computer• System Configuration Module• Alternate Display (or optional monochrome WX-1000/SKY497 display)• Directional Antenna, NY156 or NY164 (depending on TCAS I or TAS installation)SKY899 is an active system that operates as an aircraft-to-aircraft interrogation device. The SKY899equipment interrogates transponders in the surrounding airspace similar to ground based radars. Whenreplies to these active interrogations are received, the responding aircraft’s range, altitude, and closurerates are computed to plot traffic location and predict collision threats. The effective active range isapproximately 20 nmi. The SKY899 does not transmit ADS-B interrogations, in order to transmit youraircraft position you must have a mode S transponder capable of ADS-B interrogations.Figure 1-1 shows the SKY899 vertical display modes used to display intruding aircraft. The unrestrictedaltitude of the surveillance zone is ±10,000 ft, but the display is only capable of showing to ±9,900 ft. Asimplified block diagram of the system and their relationships is shown in figure 1-2.

PreliminarySKY899Installation Manual1-11Rev. A1.3.3 Display (Alternate or WX-1000/SKY497 Display P/N 78-8060-5900-x)The display used is installation dependent. If installing to meet the requirements for a TCAS I installationan alternate display device (i.e., EFIS, MFD, IVSI, weather radar indicator) approved for displaying TCASI information is required. If installing to meet requirements for a TAS installation an alternate displaydevice, the WX-1000/SKY497 display, or both can be used as primary means for displaying trafficinformation.When interfaced to both displays (alternate display and WX-1000/SKY497 display), display functions canbe linked together or separate depending on the capabilities of the alternate display. When installed withan alternate display device only, the service menu cannot be accessed via the display, therefore a terminaldevice (i.e., laptop) is required for system setup and post-installation checkout (see appendix F). If bothdisplays are connected the service menu can be accessed by the WX-1000/SKY497 display only.The SKY899 is designed to transmit traffic information to the alternate display device via our ARINC-429bus interface (100 kHz fixed speed). Refer to display manufacturer instructions for installation details.WX-1000/SKY497 Display P/N 78-8060-5900-x. To operate with SKYWATCH HP, existing WX-1000displays must conform to TSO-C113. If the equipment tag on the back of the unit (see figure 1-7) does notidentify SKYWATCH and TSO-C113, return the display to the factory for modification. To scheduleworkload and ensure a quick turn around, a return authorization will be required.

Connections are made through two TNC and oneBNC connector. The antenna is sealed against environmental extremes and is non-repairable. To ensure atight seal between the airframe and antenna, an O-ring seal (i.e., an O-ring groove for an MS28775-044 O-ring) has been incorporated into the design. An O-ring is supplied with each antenna and must be installedwhen mounting the antenna.To fit specific airframes, a special adapter plate is also required. The adapter plate is included in theinstallation kit shipped with each system. Refer to table 1-4 for a list of installation kits associated withvarious airframes. For aircraft not listed, contact the aircraft manufacturer for information relative to theradius of the area where the antenna is to be mounted. Table 1-5 lists the contents of each installation kit.The installation kits differ only in the size of the special airframe adapter plate. Figure 1-9 depicts theantenna dimensions.Table 1-4.

PreliminarySKY899Installation Manual2-1Rev. ACHAPTER 2INSTALLATION2.1  INTRODUCTIONThe information and instructions provided in this section are directed toward fixed-wing aircraft. Thecomplex nature of rotorcraft installations (e.g., antenna placement; composite versus metal blades,available ground plane, rotor mast interference, strike kits, etc.) requires that each installation beevaluated on a case-by-case basis. Before starting a rotorcraft installation, contact Field ServiceEngineering at 1-800-453-0288 or 1-616-949-6600.NOTETolerances (unless otherwise indicated):ANGLES ARE ± 1°.00 TWO PLACE DECIMALS ARE ± .02.000 THREE PLACE DECIMALS ARE ± .010Installation must be made by qualified personnel, in conformance with applicable government regulations.This information furnished is for convenience only.NOTES1. The conditions and test required for TSO approval of this article are minimumperformance standards. It is the responsibility of those installing this article eitheron or within a specific type or class of aircraft to determine that the aircraftinstallation conditions are within the TSO standards. The article may be installedonly if the installation is performed in accordance with Part 43 or the applicableairworthiness requirements.2. Installation instructions for the WX-1000 processor are detailed in the WX-1000Installation Manual.2.2  UNPACKING, INSPECTION AND STORAGECAUTIONThe display and TRC are sensitive to electrostatic discharge (ESD) and maybe damaged if not handled correctly. Do not remove protective covers fromelectrical connectors during unpacking. Touching an exposed connector maycause electrostatic damage to equipment.Carefully unpack the system and note any damage to shipping containers or equipment. Visually inspecteach component for evidence of damage. Compare the equipment received with that noted on the packinglist. Immediately report any missing items or evidence of damage to the carrier making the delivery. Tojustify a claim, retain the original shipping container and all packing materials.Every effort should be made to retain the original shipping containers for storage. If the originalcontainers are not available, a separate cardboard container should be prepared that is large enough toaccommodate sufficient packing material to prevent movement. The ambient temperature of the storagearea should not fall below -55 °C (-67 °F) or rise above 85 °C (185 °F).
PreliminarySKY899Installation Manual2-2Rev. A2.3  ANTENNA LOCATIONLocation is an important factor for maximum antenna performance. Optimum location for a particularaircraft type is usually available from the aircraft manufacturer. In selecting a location, consider thefollowing:Directional Antenna The mounting site should be on the top forward fuselage, as close to thecenterline as possible, and within -10° of the in-flight horizon (see figure 2-1).The optimum mounting point for maximum coverage is as far forward aspossible without exceeding the -10° forward pitch. If necessary, considerationshould be given to relocating other antennas to obtain the furthest forwardlocation for the directional antenna. The antenna should be mounted on theaircraft with at least 20 dB isolation (about 30 inches (76.2 cm)) from other L-band frequency antennas and 24 inches (61.0 cm) from other antennas orobstructions. The ground-plane should be as large as possible, a 30-inch (76.2cm) ground-plane diameter is recommended.The directional antenna can be bottom mounted only if a suitable top mountlocation is not available. Each bottom mount installation must be evaluated ona case-by-case basis. Before starting a bottom mount installation, contact FieldService Engineering at 1-800-453-0288 or 1-616-949-6600.Figure 2-1. Directional Antenna Mounting Location2.4  TRC LOCATIONTypically the TRC is installed in the electronics bay. In selecting a location, consider the following:Cable Length Cable runs should be as short as practicable in order to minimize potentialelectrical interference. Cable length to antennas must not exceed the values listedin table 1-6.Cooling While the TRC has no special cooling requirements, it should be mounted to permitadequate ventilation. Caution should be observed to not inhibit airflow from therear mounted fan. Allow at least three inches (8 cm) of rear clearance.Pressurized Aircraft The TRC may mount inside or outside the pressure vessel. The TRC contains nobatteries or potentially explosive components and will operate up to 55,000 ft.

PreliminarySKY899Installation Manual2-15Rev. A2.5  DISPLAY LOCATIONThe display should be mounted in a location easily accessible and clearly visible to the pilot. If using analternate display device refer to manufacturer instructions for location. In selecting a location for WX-1000/SKY497 display, consider the following:Magnetic Effect Where possible to avoid it, the display should not be mounted within3 inches (8 cm) of an electric turn and bank indicator, as the magneticeffect of the turn and bank motor may affect the display presentation. (Acommon symptom of magnetic interference is a wobbling or vibratingdisplay raster.)NOTEIf it is necessary to mount the display unit next to a device that may affectthe CRT display, magnetic shielding material can be placed around thedisplay unit. Shielding material is available from BFG Avionics Systems.Specify P/N 78-8060-5882-8 when ordering.Panel Depth Adequate depth must be available behind the instrument panel to allow forthe display, the display connector, and excess display cable. Rememberthat a service loop is necessary to allow access to the display connectorwhen removing the display or inserting it into the instrument panel.Cooling While the display has no special cooling requirements, it should bemounted to permit adequate ventilation.Viewing Angle The viewing angle for the CRT display is not a critical factor. The mostfavorable mounting position would be near eye level and no more thanarms length from the principle user of the instrument.
PreliminarySKY899Installation Manual2-16Rev. A2.6  CABLE REQUIREMENTS AND FABRICATIONThe installer will supply and fabricate all system cables. Cable specifications and approved vendors areprovided in paragraph 1.7, equipment required but not supplied. Appendix A defines the electricalcharacteristics of all input and output signals and identifies the cable requirements for each signal.Required connectors and contact pins are supplied in the installation kits.NOTES1. Use of any cable not meeting BFG Avionics Systems specifications voidsall system warranties.2. All wiring must be in accordance with industry accepted methods,techniques and practices.3. All wires are 22 AWG. except where noted, refer to figures 2-2, 2-3 and2-4 for interconnect wiring information.The length and routing of the external cables must be carefully studied and planned before attemptinginstallation of the equipment. Observe the following precautions:• ARINC-429 inputs (receive channels) must be paired with other ARINC-429 inputs of the samespeed (12.5 or 100 kHz). Details are outlined in paragraph 2.9.• All cable routing should be kept as short and direct as possible.• Avoid routing the cables too close to aircraft control cables.• Avoid routing cable near the ADF, comm radio, or transponder antenna cables (allow at least a 12inch (30.5 cm) separation).• Avoid routing cable near power sources (e.g., 400 Hz generators, trim motors, etc.) and near powerfor fluorescent lighting.• Use pressurized bulkhead connectors certified for your specific aircraft pressurization.• To limit the possibility of wire chafing, it is recommended that heat shrink sleeving be installedover the wire bundle between the shield termination’s (inside the connector backshell) and theconnector cable clamp.• Observe all wiring notes on interconnect wiring diagram (figures 2-2, 2-3 and 2-4).After fabricating the cables and before installing the equipment, use the interconnect diagram to verifycontinuity between each pin and its opposite end termination. Check resistance to ground between eachconnector pin. When a path to ground is detected, verify its validity. Figure A-1 P1 connector pinidentifiers has been added to assist in fabrication and continuity verification of the interconnect cable.
PreliminarySKY899Installation Manual2-17Rev. A2.6.1  Antenna CablesNOTES1. Use of any cable not meeting BFGoodrich Avionics Systems specificationsvoids all system warranties.2. If you fabricate your own cables, you must verify that the attenuation andVSWR does not exceed the specified values.3. To add strain relief and alleviate stress caused by aircraft vibration, place 4-6 inches (10.2 to 15.2 cm) of heat shrink tubing over each antenna connectorand cable.The directional antenna requires three cable assemblies; sum (Sigma Port), bit probe (Probe Port) anddifference (Delta Port). Cable attenuation for the sum and difference ports must not exceed 2.5 dB.Attenuation for the bit probe cable must not exceed 6 dB. VSWR, on cables attached to the sum, bit probe,and difference ports, must not exceed 1.5:1. (See paragraph 1.7 for antenna cable vendors andspecifications.)At the antenna, each connector has an identifying color band. To ensure the cables are connected to thecorrect port, affix the following marking at the termination points of each cable:Sum (Sigma) Port The Sum (Sigma) port is the forward antenna connector. It is marked witha blue band. Fabricate the sum antenna cable with a TNC connector ateach end. Affix a blue marking band on each connector. At the TRC, thesum port (J9) is identified with blue marking.Bit Probe Port The Bit Probe port is the center antenna connector. Fabricate the probecable with a BNC connector at each end.Difference (Delta) Port The Difference (Delta) port is the rear antenna connector. It is marked witha red band. Fabricate the difference antenna cable with a TNC connector ateach end. Affix red marking band on each connector. At the TRC, thedifference port (J11) is identified with red marking.When routing antenna cables, observe the following precautions:• All cable routing should be kept as short (do not exceed maximum cable length detailed in table 1-6) and direct as possible.• Avoid sharp bends (do not exceed maximum bend radius detailed in table 1-6).• Avoid routing cable near power sources (e.g., 400 Hz generators, trim motors, etc.) and near powerfor fluorescent lighting.• Avoid routing cable near ADF antenna cable (allow at least a 12-inch (30.5) separation).2.6.2  Audio Output CableFor audio output cable use #22 AWG (minimum) twisted shielded pairs with the shield grounded at bothends. Cable runs can be up to 30 ft., but should be as short as practicable.2.6.3  Data CablesRS-232, RS-422, and ARINC-429 data cables are #22 AWG (minimum) twisted, shielded cables. The shieldshall be grounded at both ends and at all breaks. Cable runs should be as short as practicable.

The SKY899 is a new system with the addition of a system configuration module and a newTRC899. Even though the TRC899 resembles a TRC497, uses the same antenna and mounting hardware,the external connector P1 has different pinouts and is keyed differently to prevent the possibility ofdamaging a TRC. In order to relocate pin positions use the insertion and extraction tools listed inparagraph 1.7, under sub title "Connector Installation."NOTEAll P1 connections will need to be moved from an existing pin location to anew pin location, as well as the addition of the system configuration module.Only the power and antenna connections remain the same.Some of the differences:TRC899 TRC497• 7 ARINC-429 RX channels 2 ARINC-429 RX channels• 3 ARINC-429 TX channels 1 ARINC-429 TX channel• System Configuration Module(configure system in service menu)Individual configuration pins• Heading valid, 1 input pin(low/high level selected in service menu)Heading valid, 2 input pins (low or high level)• Analog radio altimeter Not available• 18 - 32 V dc power input 11 - 34 V dc power input• ADS-B (requires mode S transponder address) Not available• Altimeter Gilham Code "D2" added(do not connect if not available)Altimeter Gilham Code "D2" not available• Lamp Outputs - above, below and oper_mode(used with alternate display)Not available• Transponder input/output Not available• Stepper (heading) not available Stepper (heading) available
PreliminarySKY899Installation Manual2-21Rev. A2.7  AIRCRAFT DISCRETE INPUTSThe aircraft discrete inputs are used to assist in determining the aircraft's phase of flight or flightcondition (e.g., on ground or in flight). Inputs are diode isolated inside the TRC, do not install isolationdiodes externally. The active or inactive state of the inputs can be high or low, they will be saved in theSystem Configuration Module during system setup using the service menu.2.7.1  Audio Inhibit (Terrain Warning System - GPWS)The audio inhibit input will sense a terrain warning alarm (i.e., GPWS, EGPWS, TAWS) and temporarilydisable the audio alert output until the terrain warning clears. The input can be either a constant flagsignal or an alternating flag output. The flag must be cleared for 5 seconds before the TRC accepts a “NOALARM” condition and restores audible alerts.NOTES1. If the aircraft is equipped with terrain warning system, it must be connectedto the TRC.2. If the aircraft is not equipped with terrain warning system, leave this inputunconnected.Audio inhibit connection:GPWS P1-342.7.2  Landing GearThis input is to be connected to the landing gear switch to sense the position of the landing gear (fixed, upor down). The switch status of this input is selected during system setup via the service menu. This inputhas three service menu options, none (fixed gear), active low (electrically ground with aircraft on theground) and active high (electrically high (+9 V to +28 V) with aircraft on the ground).Landing gear connection:GEAR P1-33If the aircraft does not have a landing gear switch (e.g., fixed-gear aircraft), leave this input unconnected.With this configuration, if a radio altimeter (analog or ARINC-429) is not installed, the system will defaultto the highest TA sensitivity level (level B) and audio TA announcements (i.e., “traffic, traffic”) will not beinhibited during takeoff and landing.2.7.3  SKYWATCH/Stormscope Mode SwitchThe SKYWATCH/Stormscope mode switch (SW1) is required only if a WX-1000 Stormscope WeatherMapping System is installed. This switch permits the flight crew to switch the display between theSKY899 and WX-1000. If a TA (Traffic Advisory) is detected while in the Stormscope mode, the display willswitch to the SKYWATCH mode. Refer to figure 2-3 for interconnect wiring information. Any generalpurpose SPST toggle switch (3 Amp @ 28 V dc) may be used. Display mode switch cable routing and lengthare not critical to system operation. Mount the switch at a location easily accessible to the pilot.SKYWATCH/Stormscope mode switch connections:SMS P1-15SMS_RET P1-232.7.4  Squat Switch (Weight-On-Wheels)This input is to be connected to the squat switch (weight-on-wheels) to sense when the aircraft is on theground. The switch status of this input is selected during system setup via the service menu. This inputhas three service menu options, none (no squat switch installed), active low (electrically ground withaircraft on the ground) and active high (electrically high (+9 V to +28 V) with aircraft on the ground).
PreliminarySKY899Installation Manual2-22Rev. ANOTEIf the aircraft is not equipped with a squat switch, it is recommended that asquat switch be installed.Squat switch connection:SQUAT P1-24If a squat switch is not available, this input could be tied to an airspeed switch inline with the pitot systemas an alternate input for the squat switch. In this configuration care should be taken to ensure the switchis set to trigger at a speed consistent with take-off and landing.On helicopter installations with skids, and a squat switch is not available, this input can be tied to thecollective switch. In this configuration care should be taken to ensure the switch is connected to provide aground when the aircraft is on the ground and open when the aircraft is airborne.If it is not possible to install a squat switch, airspeed switch, or collective switch, select none in servicemenu. With this configuration the pilot must toggle the system in and out of standby manually. Trafficwill only be displayed when the pilot switches out of the standby position.With a squat switch installed, SKYWATCH HP will automatically switch out of standby 8 to 10 secondsafter takeoff and switch back to standby 24 seconds after landing. A squat switch would also prevent thepilot from placing SKYWATCH HP in standby (i.e., pressing the →→→→STB button) while the aircraft is in-flight.2.7.5  ON/OFF Power SwitchThis input connection turns the TRC ON and OFF. Wiring of this input will vary depending upon yourspecific installation. With pin P1-4 connected to P1-5 the system will turn on. There are three possibleconfigurations discussed below:Alternate Display. A separate ON/OFF switch is required (any SPDT toggle switch rated at 3A @ 28 V dccan be used). Refer to display manufactures instructions and figure 2-4 concerning this connection.WX-1000/SKY497 Display (without WX-1000). Connect per figure 2-2.Stormscope WX-1000 Installation. This external over-ride switch (SW2) is required if a WX-1000Stormscope Weather Mapping System is installed. The override switch enables the SKYWATCH HP to bepowered-up if the WX-1000 processor has been removed for maintenance. During normal operation theswitch should remain in the NORMAL position and moved to OVERRIDE only if the WX-1000 processorhas been removed for service or if it is necessary to access the WX-1000 service menu. Connect per figure2-3Any general purpose DPDT toggle switch (3 Amp @ 28 V dc) may be used. The maintenance switch cablerouting and length are not critical to system operation. The switch can be located in the avionics bay nearthe WX-1000 processor.ON/OFF power switch connection:ON/OFF P1-4ON/OFF_RET P1-52.8  ALTERNATE DISPLAYAlternate display (ARINC-735 compatible is required for TCAS I installation) is connected to ARINC-429output channel. Refer to paragraph 2.9 for ARINC-429 output channel information.
PreliminarySKY899Installation Manual2-23Rev. A2.9  ARINC-429The ARINC-429 interface can be divided into four sections: general sensor inputs, mode S transponderinput/output, alternate display output and future input/output options. The TRC has seven receivechannels and three transmit channels that are used to accomplish the various interfaces. However, tworeceiver and two transmitter channels are not used at this time (future option). ARINC-429 labelsaccepted and transmitted are listed in tables A-3 and A-4.2.9.1  General Sensor InputsThe TRC can use four general sensor inputs: barometric altimeter, radio altimeter, magnetic heading, andGPS navigation data. Five receive channels have been designated for these inputs and will allow variouscombinations of speed and equipment types. It is also possible for multiple data inputs (barometricaltimeter, radio altimeter, magnetic heading and GPS navigation) from one source to be received on onechannel (e.g., ARINC-429 superbus). Receiver speed and equipment type must be set via the service menu.When planning the ARINC-429 interface note the following:NOTES1. The data rate for RX channels 1 and 2 must be set to the same speed(12.5 or 100 kHz).2. The data rate for RX channels 3 and 4 must be set to the same speed(12.5 or 100 kHz).3. The data rate for channel 5 is independent of the other receivers.Channel 5 can be set to 12.5 or 100 kHz.ARINC-429 General Sensor Input connections:A429RX1_A (P1-54)A429RX1_B (P1-55)A429RX2_A (P1-62)A429RX2_B (P1-63)A429RX3_A (P1-64)A429RX3_B (P1-65)A429RX4_A (P1-73)A429RX4_B (P1-74)A429RX5_A (P1-75)A429RX5_B (P1-76)2.9.2  Mode S Transponder I/O (future option)The TRC has one receive and one transmit channel designated for the mode S transponder XT & TX businterface. The receiver and transmit speed is fixed at 100 kHz. This is a future option, do not connect atthis time.Mode S Transponder XT bus connections:A429RX7_A (P1-83)A429RX7_B (P1-84)Mode S Transponder TX bus connections:A429TX2_A (P1-44)A429TX2_B (P1-45)
PreliminarySKY899Installation Manual2-24Rev. A2.9.3  Alternate Display OutputThe TRC has one transmit channel designated for alternate displays (i.e., EFIS, MFD and weather radarvia RGC250). The transmitter speed is fixed at 100 kHz. The display driver must be selected via theservice menu.

AAPPENDIX ASKY899 INTERFACESIGNAL & CABLE CHARACTERISTICSA.1 INTRODUCTIONThis appendix defines the electrical characteristics of all input/output signals to the TRC899 and the labelsfor the ARINC-429 data bus. Sufficient data is included to perform an electrical load analysis for theaircraft. The interface characteristics contained in this appendix are fully compatible with ARINCspecifications where noted. Connection information identifies connector-pin and signal names as theyappear on interconnect wiring diagram, figure A-1 shows P1 connector pin locations and signal names.NOTEExternal isolation diodes are not required and SHOULD NOT be installed.A.2 ELECTRICAL CHARACTERISTICSSIGNAL CHARACTERISTICSAltitude (Gilham Code) / These uncorrected barometric signals are Gilham code (or gray code)Encoding Altimeter Input  inputs coming from an airdata computer or encoding altimeter (seeparagraph 2.11). These 11 lines may be connected in parallel with theaircraft transponder. If the aircraft is equipped with selectable altitudeencoders, connect the altitude inputs so that SKY899 is always connectedto the selected encoder. (Reference ARINC 572-1.)NOTES1. Only one altimeter input source (gray code or ARINC-429, not both)should be connected. The altimeter input should be from the samesource that is interfaced with the transponder or at least as accurate asthat source, i.e., ± 125 ft.2. If the aircraft has switched encoders that use 28V RETURN orAIRCRAFT GROUND as reference for encoder selection, thenALT_COMMON (P1-72) should be left unconnected.3.

Refer to paragraph 2.6.1.Impedance: 50 ΩARINC-429 External Interface The SKY899 has seven ARINC-429 receivers and three transmitter(paragraph 2.9). Four of the channels are paired internally and canoperate at either low speed (12.5 kHz) or high speed (100 kHz). However,the paired channels must be set to the same speed (see tables A-1 and A-2). The transmitters operate only at high speed (100 kHz).The first ARINC-429 transmitter (A429TX1) is intended to provide thecapability to interface with alternate display device. The second and thirdARINC-429 transmitters (A429TX2 & TX3) are a future option.Five of the ARINC-429 receivers can be used to input data from otheravionics systems. The sixth and seventh receivers are not used at this time(future option).NOTES1. The radio altimeter must provide full range output between 0 and2500 feet. Not all altimeters provide this full range output. The fullrange output can sometimes be obtained as a mod to the radioaltimeter . Check with the specific altimeter manufacturer forcompatibility and availability of modification, if necessary.2. The TRC can accept Radio Altimeter input from ARINC-429 or DCanalog source. The Barometric Altitude can be ARINC-429 orGilham Code. The Magnetic Heading can be ARINC-429 or Synchro(XYZ). Select only one source for each aircraft input.3. If 429 barometric altitude is used, it should be from the same sourcethat is interfaced with the transponder or it must be at least asaccurate as that source, i.e., ± 125 ft.4. Receive channels 1 and 2 must be set to the same speed (12.5 or 100kHz). Receive channels 3 and 4 must be set to the same speed (12.5or 100 kHz). Channel 5 is independent of the other receivers andcan be to 12.5 or 100 kHz.

(If System Setup has already been done, proceed to nextstep.)5. Turn SKY899 OFF and then enter the Service Menu (see paragraph 4.4) by holding the left twobuttons (soft-keys 1 and 2) depressed as the system is turned ON.6. From the Service Menu, calibrate the TRC to the directional antenna (see paragraph 4.4.3). Ifcalibration was just done during System Setup (see paragraph 3.3.1) proceed to next step.7. Return to the Service Menu and select Information.8. From the Information menu, select Data Monitor. The Data Monitors menu will appear.9. Select each of the data monitors and verify the sensor information is correct (see paragraph 4.4.2.3):a. Change the status of the landing gear, squat switch, altitude, and heading sensors.Verify data monitors show the correct input changes (i.e., sensing of these signals).
PreliminarySKY899Installation ManualC-4Rev. Ab. If the information is not correct, the sensor has failed to communicate with the TRC. Checkoperation of the sensor and connections between the TRC and sensor.c. Select exit until you return to the Service Menu.10. Do SKY899 self test (paragraph 3.4).11. From the Service Menu, select Ground Test (see paragraph 4.4.4).12. From Ground Test menu, select Perform Ground Test.13. Verify operation of range function. Soft-key (3) is labeled to indicate the current range. Press soft-key(3) to toggle the display range between 2, 6 and 15 nm.14. Select the 6 nautical mile range.15. Verify that the system toggles through the altitude display modes. Soft-key (2) is labeled to indicatethe current mode. Press Soft-key (2) to select normal (NRM), below (BLW), and above (ABV).16. Select the NRM (normal) mode.17. Position the aircraft with the nose aligned on any 90 degree heading. Avoid areas within 250 ft ofobstructions (e.g., hangers, large aircraft, control towers, etc.) where there is a potential for multipathproblems. Locate and mark test points, every 30 degrees (i.e., at 000, 030, 060, 090, 120, 150, 180, 210,240, 270, 300, and 330 degrees with respect to the SKY899 directional antenna). Mark these points atthe same distance, approximately 100 ft, from the aircraft.18. Do the following static tests:a. Connect the TCAS-201 Flat Antenna (facing towards the test aircraft) to the antenna connector.b. At the TCAS-201 test set, press the REPLY TEST key.c. Initiate the REPLY TEST by pressing the ANTENNA push button switch or the RUN/STOPkey.NOTEThe TCAS-201 display will indicate “NO WHISPER-SHOUT SEQUENCE”.d. Verify that the SKY899 display shows an other traffic symbol (open diamond) at the 12 O'clockposition (±30 degrees), approximately 5.0 nm, in level flight, and at an altitude of 500 ft aboveown aircraft (i.e., "+05").NOTES1. If the display reflects a gross error in target bearing, check the directional antenna cablesat TRC connectors J9 (sum port) and J11 (difference port). They may be reversed. A furtherindication of this condition would be a target that moved in a counter-clockwise directionwhen the test set is moved in a clockwise direction.2. Multiple targets or a faulty bearing may result from multipath distortion(see step 2).3. During these tests, the SKY899 may detect and display other active targets.e. Repeat a, b, c, and d from each of the test points (see step 2).19. Do the following dynamic test.a. Position the ramp test set on the test point directly in front of the test aircraft (i.e.,approximately 100 ft in front of the aircraft, see step 2).b. Connect the TCAS-201 Flat Antenna (facing towards the test aircraft) to the antenna connector.c. At the TCAS-201 test set, press the SCEN key.d. Initiate the SCENARIO TEST by pressing the ANTENNA push button switch or theRUN/STOP key.
PreliminarySKY899Installation ManualC-5Rev. Ae. Verify that the display shows an "other traffic" symbol (open diamond) at the 12 o'clock position(±30 degrees) approximately 5.0 nm and in level flight. The traffic symbol should be at analtitude of 500 ft above own aircraft (i.e., "+05") and moving towards your aircraft.f. When the target approaches closer than approximately 1 nm from own aircraft, verify that thesymbol changes from an other traffic symbol (open diamond) to a traffic advisory (solid circle).NOTEThe voice message, “TRAFFIC, TRAFFIC,” will be enunciated over thecockpit audio system.g. The target, when it reaches 0.0 nm, will reverse direction and move outbound on the sameheading.NOTEThe target may momentarily drop from the display and then reappear as another traffic symbol (open diamond).20.

A varying delay time,controlled from the microprocessor, delays the replies returned to the SKY899 from as far as 14 nauticalmiles and as close as a few hundred feet. The apparent distance from the simulated intruder to theSKY899 system under test decreases as if the intruder was converging on the aircraft under test. The testset determines the altitude of the aircraft under test by interrogating the transponder using an ATCRBSinterrogation. By adding or subtracting the desired differential altitude, as selected by the front-panelscenario switch, the initial altitude of the scenario is controlled by the microprocessor. This altitude, likethe distance, is varied so that the simulated intruder converges on the aircraft’s position.1. Make sure the aircraft's transponder is in the STBY mode and the DME is turned OFF. At theaircraft's instruments, verify all compass/HSI flags are valid.NOTEAfter power up, it may take a couple of minutes for the altitude encoder toreturn a valid altitude to the transponder and SKY899.2. Turn SKY899 ON. The display will show a start-up screen similar to one shown in figure D-2. Afterstart-up screen appears, rotate the OFF/BRT switch. Verify that clockwise rotation increases displaybrightness.Figure D-2. Start-up ScreenAfter approximately thirty seconds the display will show the STANDBY screen (see figure D-3).NOTEIf the TRC has not been calibrated to the directional antenna the displaymay show a “SKY899 FAILED” message. Calibration will be done duringsystem setup.

Position the T-49C Flightline Tester on one of the test points identified in previous step.CAUTIONThe Flightline Tester is not weatherproof when the lid is open. Do not setupor operate the Flightline Tester in conditions of rain, sleet, etc.19. Setup and verify operation of the T-49C Flightline Tester with the HI/LOW power switch in the HIposition and then:a. Set the TCAS INTRUDER selector switch of the T-49C to the ATCRBS/Mode-S XPDR TESTposition and press TEST and the INTERROGATE. This will store the aircraft’s barometricaltitude in the T-49C.NOTEThe T49-C will display the pressure altitude of the aircraft under test.b. Verify that the SKY899 display shows the standby screen (figure D-3) and then press soft-key(4), labeled OPR. Select NRM mode and 6 nm range by pressing appropriate soft-keys.c. Set the TCAS INTRUDER selector switch to the ATCRBS position and the SCENARIO selectorswitch to the 0 altitude offset position. Press INTERROGATE, and when the range on thedisplay decreases to 5 NM, press TEST. This will freeze the scenario and represent a stationaryintruder aircraft 5 NM away at the same altitude as the UUT aircraft. Verify that the SKY899displays, in the direction (±30 degrees) of the T-49C, a symbol for other traffic (i.e., opendiamond) at 5 NM. Target will be displayed in level flight at own aircraft altitude (i.e., “00”displayed above the traffic symbol).NOTES1) If the display reflects a gross error in target bearing, check the SKY899directional antenna cables at TRC connectors J9 (sum port) and J11(difference port). They may be reversed. A further indication of thiscondition would be a target that moved in a counter-clockwise directionwhen the T-49C is moved in a clockwise direction.2) Multiple targets or a faulty bearing may result from multipath distortion(see step 1).3) During these tests, the SKY899 may detect and display other activetargets.4) To obtain a better line of sight, it may be necessary to elevate theantenna.d. Move the T-49C to each test point and verify that the display shows the corresponding bearingdisplacement.NOTEIt is necessary to wait a few seconds after moving to let the test target stabilizein position.20. This completes testing with the T-49C, reattach top lid of the T-49C.21. If installed, TURN ON the radio altimeter.22. This completes the post installation checkout procedure.
