3-27 ADTS542F/552F/553F/554F User ManualK0553 Revision A3.9 Manual Venting of the Aircraft Pitot and Static SystemsADTS status on power failureOn removal of power, the main output valve linking external ports Pt and Ps to the internal pressure controllers will automatically close. The aircraft pitot and static systems remain safe but with the last applied pressures now isolated and maintained in the hoses. ADTS status on restoration of powerWhen power is restored to the ADTS the normal self test routine for the ADTS will be performed and at the end of this the ADTS will exactly equalize the internal manifold pressures to match those of the external aircraft hoses and then the output valves will be reopened. This process will at all times protect the aircraft pitot and static systems from adverse pressure transients, differentials or excessive rates.When the output valves are fully opened, the normal parameter measurement screens become available from the Dashboard and full control is again available. The testing may then either continue from the same point (when the power failure occurred) or the aircraft pitot and static systems may be safely controlled back to ground pressures.Actions if power cannot be quickly restoredTwo courses of action are possible at this point:1. Leave the ADTS connected to the aircraft pitot and static systems with pipes safely isolated but maintaining trapped pressures until such time as power can be restored.2. Use the manual let-down valves on the ADTS front panel to safely bleed the trapped hose pressures back to ambient ground. This must be carried out in a way that ensures the Pt to Ps differential pressure remains at zero while the whole connected system is brought to ground pressure.Open the valves slowly while monitoring the cockpit gauges for any excessive rate of change.The order the manual let-down valves are opened is:Figure 3-19 Manual let-down ADTS542F and ADTS552FNumber of Channels Application 1st Valve open 2nd Valve open 3rd Valve open 4th Valve open2 Pitot & Static Pt to Ps (A) Ps to Atm (B) N/A N/A

3-29 ADTS542F/552F/553F/554F User ManualK0553 Revision A3.10 Example Basic Aircraft Test Operation using the ADTS542FPreparation for TestingIf unfamiliar with the features and functions of the ADTS542F then it is important for operators to read and understand the following documents before use:• Safety and Installation Guide K0554.• User Manual K0553 (this document).If the ADTS542F proposed for use has just been delivered, been stored for an extended period or the operability is unknown for any reason, then perform a standard serviceability test of the ADTS before use on aircraft. Details of this test can be found in section 6.2.Familiarise yourself with all aircraft specific test requirement s, personal and aircraft safety precautions from the manufacturer’s Aircraft Maintenance Manual (AMM).Aircraft ConnectionsFirstly, consider where to place the ADTS base unit such that it can be safely accessed by the operator but also has practical routes for piping to the aircraft ports that will not get knocked or damaged during test operations. This may be either on the hangar/apron floor or a cockpit level gantry.Any difference in height between the ADTS front panel and the aircraft ports must be configured on the ADTS as an altitude correction (see section 2.6). If working on the aircraft outdoors, the signal strength of the radio data link to the ADTS Touch will be optimised if the ADTS is placed with line of sight to the cockpit windows.Assess the hose lengths that will be required and provision either from the ADTS542F delivery kit or from local stores. The ADTS542F is supplied with low temperature red and blue flexible hoses at 3m length as standard, but longer hoses may be requested to order. A configurable label kit is provided so that Ps and Pt channel colour coding may be set in line with regional standards. Both of the standard hoses come with ready fitted AN4 size fittings suitable for the ADTS Ps and Pt output ports.The other end of each hose is open to allow users to fit hose extensions or other pressure adaptors as required.The direct connections to the aircraft Pitot and Static ports should be made using the adaptor set approved in the AMM, or using equivalents supplied by a specialist port adaptor manufacturer. We do not recommend the use of improvised connections since this can lead to excessive leakage and potential damage to the aircraft avionics systems.When all the required pipework has been connected, the ADTS should be turned on as soon as possible to allow a few minutes for it to reach a stable operating temperature. This is a safe action for the aircraft regardless of whether the ADTS Touch is connected or not at this time. No changes in pressure will be applied to the aircraft until actively requested. Make the ADTS Touch data connection to the ADTS, either by Bluetooth® data connection or cable (see section 3.2).Altimeter and Airspeed Indicator TestingLimits Protection ChecksThe ADTS will automatically power up with the HELICOPTER limits in force. This table enforces the most restricted control range on the ADTS output pressures, so this default configuration is the safest of the three predefine limit sets if working on small, low speed aircraft.
ADTS542F/552F/553F/554F User Manual 3-30K0553 Revision AConsult the AMM to check the approved maximum test ranges for Altitude, Rate of Climb, Airspeed and Mach for your aircraft. It is important to have the ADTS limits set correctly configured for the following reasons:a) Prevents operators mistakenly entering test aims which exceed the aircraft maximums.b) Provides early real time warnings that ranges and rates are being exceeded (due to Pitot Static system leak etc.).c) Will prevent inadvertent creation of excessive Mach conditions due to selection of inappropriate altitude and airspeed combinations.d) Will ensure that the ADTS can successfully reach any extended range test points as required.Consult the ADTS limits values for the three predefined tables, HELICOPTER, FIXED WING and MAX AERO in the SETTINGS menu (see section 3.6). If a suitable protective limits match cannot be found in one of the three predefined tables then choose CREATE NEW LIMITS and edit your own custom limits table name and preferred values from the offered starting values. This protected operation will require use of the Supervisor PIN code. Any attempt to enter limit values greater than the ADTS pneumatic control maximums will create a warning to the user requesting a lower value. Before attempting to create a new custom named limit, first check that there are no more than 4 existing user named tables. A maximum of 5 only are allowed, but old unused tables can be deleted as required.Leak ChecksSince the leak status of the aircraft is initially likely to be unknown, it is recommended to perform a preliminary assessment at low altitude and airspeed stimulus so as to minimise risk to the aircraft instruments, should a high rate leak be present. It is also strongly recommended to enable the ADTS “AUTO LEAK RECOVERY” function. This will automatically attempt to regain control of the aircraft pressures if the measured rates of change (leak rate) exceed 3000 feet/min or 600 knots/min.If no specific leak check procedure is described in the AMM, first select safe rates of parameter change for the Ps and Pt channels according to aircraft type. It is suggested to start with simultaneous aims of 2000 feet and 200 knots, following the procedure described for the standard equipment serviceability test described in section 6.2.Correct any leak issues found with the hose connections or aircraft systems before proceeding with further testing. The leak status of the ADTS alone may be verified using the procedures in section 6.3.Typical Aircraft Instrument Performance ChecksThe required aircraft specific procedures will be detailed in the AMM but the following generic test is provided purely as an example of how the ADTS facilities might be best utilised.The ADTS produces controlled altitudes based on the standard sea level pressure (zero feet reference) that is defined in the ICAO international standard atmosphere model. In order to correctly check the aircraft instruments for accuracy against the ADTS, it is vital that the altimeter baroscale datum adjustment is set to the same 1013.25 mbar (29.92 inHg).Systematically enter the required aims for the Ps and Pt channel from each row of the test table below. Aims may be entered either in aeronautical units or absolute/differential pressure units according to the requirements of the AMM. For each of the six test row conditions, allow the ADTS to approach and stabilise the aims until the ADTS Touch shows each measurement in green record the difference between the ADTS and the Aircraft instrument under test.
3-31 ADTS542F/552F/553F/554F User ManualK0553 Revision ABy using the ADTS Touch controls it is possible to present the Ps and Pt channel data for each of the 6 test condition rows in all of the formats shown in the table. By using the settings menu to change either the chosen pressure or aeronautical unit it is very simple to convert the displayed aims and measurement values to the desired format. Such changes can be done without turning off control, so the terminal can effectively also be used as a pressure converter/calculator when designing your aircraft test procedures.The aircraft status screen can be used to give you a very quick overview of whether the aircraft is climbing, descending or at stable altitude. If you make a mistake with your data entry, use the orange “hand” symbol to stop ramping and HOLD stable the current pressure, while you consider and correct the intended test point aim. Pressing the “hand” again will release the hold when you are ready. If the ADTS Touch loses radio link or the cable accidentally becomes severed, the ADTS will automatically enter the HOLD state after 10 seconds. If communications has not been re-established after 10 minutes, then the ADTS will automatically begin a descent to ground pressures.End of testingWhen testing is complete, use the Aircraft status screen to initiate a descent to ambient ground pressure at a safe rate. The rate may be increased or decreased if required from within this screen. To see full parameter details, simply clear the status screen view. It can be recalled at any time. If working with the ADTS .When the ADTS displays the status as AT GROUND, it is then safe to disconnect the aircraft Ps and Pt connections. The ADTS base unit will also show steady green on the rightmost aircraft status LED when in this state.Test Point Altitude (feet)Ps Pressure (mbar Abs.)Airspeed (Knots)Pt Pressure (mbar Abs.)Qc Diff.

ADTS542F/552F/553F/554F User Manual 3-32K0553 Revision A3.11 Engine Pressure Ratio (EPR)The ADTS may be used to check EPR sensors and indicators. Use Ps (static) for INLET pressure and Pt (Pitot) for OUTLET pressure.To carry out an EPR check, the display must be showing units of pressure measurement e.g. mbar, inHg.Note: Altitude correction applies to EPR values, make sure this correction does not adversely affect accuracy. The difference in height between the ADTS and the EPR sensor may be different to the altitude correction previously set for the aircraft instruments.The EPR function can be operated using one of two methods, as follows:1. Direct control of Inlet pressure and target EPR value (outlet pressure is auto-set).2.

The recommended calibration period is 12 months. If the accuracy of the system is not within the specification, carry out a calibration adjustment.4.2 PIN codes and PIN protectionThe ADTS contains some PIN protected menus. The following table lists the factory set default PIN numbers:Important noteChange these codes to prevent unauthorised access. Unauthorised access to these menus can make this system inaccurate and could, in control mode, cause excessive rates of pressure change. 4.3 Calibration processThe calibration process is PIN protected. This chapter describes the Ps and Pt sensor calibration. The “Tools”, “Calibration” “Sensor” menu contains the calibration adjustment as part of the function “Calibration check”.Note: Calibration checks must be performed from within the calibration check menu because the main Ps/Pt measure display screen Pt readings may include “Auto Zero” offset.PrecisionPrecision is a term which includes the ADTS measurement system errors of non-linearity, hysteresis and repeatability over the ADTS operating temperature range. Precision does not include errors introduced by the equipment used for calibration of the ADTS or ADTS calibration stability errors as stated on the ADTS data sheet.SettingsADTS settings Edit limits 0268Create new limits 0268Delete limits 0268Change supervisor PIN 0268ToolsCalibration (Calibrate sensors) 4321Calibration (Software update) 5487Calibration (Option configuration) 1234

It is important that the ADTS Touch clock date is checked before starting a calibration adjustment or an incorrect date may be recorded. Instructions for checking and setting the time and date can be found in section 3.6.“As found” data does not have to be recorded before an adjustment to the selected channel has been carried out. Record “as found” date as required.Preliminary operations1. Review and become familiar with the whole procedure before beginning the calibration process.2. Allow at least two hours for the ADTS to thermally stabilize after switching on and before performing any calibration routines.3. Before starting a calibration procedure carry out a leak test, see section 6.3).4. The pressure reference level of the ADTS is the top face of the front panel when the front panel is facing upwards, see also, section 2.6 “Positioning the ADTS”. In calibration check mode the ADTS sets its altitude correction to zero.Calibration checkThis procedure checks the calibration accuracy without adjusting it. It may be used either to see if the system requires a calibration or to verify performance following a calibration adjustment.1. Open the “Tools” menu, select “Calibration (Calibrate sensors), enter your PIN, select “Sensor”, “Calibration check” sub-menu showing the current values for Ps and Pt.2. Apply pressure to the selected channel to Full Scale (FS) and lowest point, repeat this process a minimum of three times.3. Ensure the standard and the ADTS are at atmospheric pressure.4. Connect your calibration standard to the Ps or Pt channel.5. Adjust the calibration standard to apply pressure to the Ps or Pt channel. Ensure that the last digit (e.g .001) of the displayed pressure is stable and free from “creep” or noise. Calculate the actual applied pressure reading to at least 4 decimal places and enter this value into the ADTS.6. The leak rate must be low enough to prevent the primary standard dead weight tester piston from moving outside the mid operating point during the calibration procedure.7. Compare the applied pressure value on the calibration standard to the value displayed on the ADTS and record the difference.8. If the recorded difference exceeds the allowable tolerance, carry out the “Calibration adjustment” procedure detailed below.9. Repeat this procedure for the other channel.Calibration adjustmentThe procedure applies known pressures to the ADTS and then entering the exact applied pressure using the ADTS Touch. After all calibration points have been entered, the ADTS automatically calculates the necessary offset (zero) and slope (span) corrections.1. Select Ps or Pt. The Ps or Pt sensor correction screen opens.2. Follow the on-screen instructions.3. Calculate the actual applied pressure reading to at least 4 decimal places and enter this value into the ADTS.
4-5 ADTS542F/552F/553F/554F User ManualK0553 Revision A4. Repeat this procedure for the other channel.The adjustment requires two pressures for each channel.
