The localizer antenna radiates a field pattern directed along the centerline of the runway towards the middle and outer markers. The antenna also furnish information outside the front course area in the form of full fly-left or full fly-right indications (CLEARANCE). All localizer installations transmit a STATION IDENTIFICATION in morse code at periodic intervals. This is a 1020 Hz tone that is keyed to form the basic station identifier. The localizer is designed to provide a signal at a minimum distance of 25 miles within +/- 10 degrees, and at a minimum distance of 17 nautical miles between +/- 10 and +/- 35 degrees from the front course line.

The cabinet and the electronics, except for RF units, are common to the LLZ and GP systems Monitor input signals Monitor Transmitter Remote Control External sensors RMS TX control Comm. ports Changeover Section NAV signals out Data and diagnostics Monitor input signals Transmitter Monitor HBK573-1 Figure3-1 ILS block diagram. The ILS cabinets can be configured for Cat I, Cat II, or Cat III requirements with no basic changes. Eight models are available: NM 7011 Single frequency LLZ NM 7012 Single frequency LLZ with hot standby monitoring (Cat III) NM 7013 Two frequency LLZ NM 7014 Two frequency LLZ with hot standby monitoring (Cat III) NM 7031 Single frequency GP NM 7032 Single frequency GP with hot standby monitoring (Cat III) NM 7033 Two frequency GP NM 7034 Two frequency GP with hot standby monitoring (Cat III) The system is based on modern technology with extensive Remote Monitoring and Maintenance capabilities, and very high reliability and integrity. To meet this objective, the monitor comparator and station control are based on digital hardware, while the RMS interface is microprocessor based. 3.2 Physical Description The cabinet contains three sections: • The electronics card cage • The change-over section • The transmitter / PA section The electronics card cage contains the RF oscillators, the LF signal generators, the monitors, SYSTEM DESCRIPTION 3-12 ©1999 Navia Aviation AS NORMARC 7011 GENERAL DESCRIPTION INSTRUMENT LANDING SYSTEM the station control, the RMS processor, and the voltage regulators. The change-over section contains coaxial relays, attenuators and phasers for the RF outputs. The transmitter / PA section contains the PA blocks including couplers etc. for each output. The cabinet is divided in two parts, with the rear part fixed to a wall, and the front part hinged to give access to interior of the cabinet. All external connections are made to the rear part of the cabinet. 3.3 Monitors The ILS has duplicated monitors with inputs for Course Line (CL), Displacement Sensitivity (DS), Near Field (NF), and Clearance (CLR) (Dual Freq. only). The signals are detected by the input stage, and then digitized. In the next block they are filtered by a Fast Fourier Transform performed by a signal processor. The results for each parameter is then compared with stored limits in a digital hardware comparator. Each of the two monitors consists of two modules. For Cat III use, Hot Standby monitoring can be added by using one additional monitor and associated RF couplers and combiners. The design of the monitors ensures a very high integrity due to the use of digital hardware for the alarm comparators and a very simple Fast Fourier filtering with a signal processor. In addition, the monitor is checked by automatic self-tests. The alarm limits are stored locally in EEPROM, and can be updated from the RMS processor, with a separate hardware write protection to ensure that the integrity is not affected by the RMS system. 3.4 Transmitters / Modulators The transmitters are duplicated, either single frequency or dual frequency. Each transmitter consists of a RF oscillator, a LF generator, and one or two PA blocks (single or dual frequency). The RF oscillator uses a synthesizer for easy frequency changes and simple logistics. The oscillator has two outputs for use in dual frequency systems. The LF generator contains the generators for 90Hz, 150Hz and 1020Hz signals, the ident keyer / sequencer and interface for DME master or slave keying. All signals are generated by division from a common clock oscillator, ensuring very stable phase relations between the modulation signals. The modulation balance, modulation sum, RF level and Ident morse code are set in this module by means of multiplying digital to analog converters. The values are stored locally in EPROM and can be updated from the RMS processor with hardware write protection. The same LF generator is used for single and dual frequency systems. 3.5 TX Control The TX control unit controls the system dependent on alarms from the monitors and inputs ©1999 Navia Aviation AS SYSTEM DESCRIPTION 3-13 GENERAL DESCRIPTION NORMARC 7011 INSTRUMENT LANDING SYSTEM from the local control, the remote control and, optionally, the RMS system. It also generate status information to the same units. The local control and status indicators are a part of the TX Control unit. All functions in the TX Control are based on digital hardware to ensure the highest integrity. 3.6 Remote Monitoring (RMS) Unit The RMS unit contains the system microprocessor. It handles storage and read-out of monitor parameters, measurements for maintenance and fault finding, and performs fault analysis to isolate faults to line replaceable modules. It is also used to set monitor limits and transmitter adjustments. The RMM handles communication to local and remote RMS computers, and in addition it handles a small display and keyboard for parameter setting and readout. 3.7 Remote Control Unit The remote control unit is used in the tower or in the technical control room. It has indicators for operating status as well as detailed warnings and an aural alarm device with reset. It can control equipment on/off and change-over, and has an Access Grant-switch to allow remote control from the RMS system. The Remote Control Unit is connected to the ILS by one telephone pair cable. 3.8 Remote Slave Panel The slave panel is connected to the remote control by a multipair wire. It is intended for use in the control tower. It has indicators for normal / warning / alarm and has an aural alarm device. in addition it can turn the equipment on and off, and has an aural alarm reset. Optionally a slave panel with remote control functionality can be delivered. 3.9 Remote Maintenance Monitoring (RMM) The NM7000 series has a built-in Remote Maintenance Monitoring system. This system consists of the RMS system, remote PC terminals with the RMM program installed, and the local keyboard/display. Figure 3-2 illustrates the RMM/RMS systems SYSTEM DESCRIPTION 3-14 ©1999 Navia Aviation AS NORMARC 7011 GENERAL DESCRIPTION INSTRUMENT LANDING SYSTEM RMM program RMM program RMM program Modem Modem Modem Modem Local Remote 1 RMS data bus Local parameter storages Maintenance data bus Local measuring points RMS hardware RMS system RMS core program Remote 2 Local Keyboard/ Display NM70xx HBK 598-1 RMM system Figure3-2 The NM 7000 series RMM/RMS systems. The centre of the RMS system is a CPU with the RMS core program. The RMS collects measurements and diagnostic data, and makes them available to the user. The collected information allows easy and cost effective maintenance, fault finding and routine reporting. In addition, system settings are distributed and parameter readings are collected via the RMS/ CPU. External personal computers are used for a user-friendly interface to the RMM system. The equipment has three serial output ports, typically used to connect a local PC, a PC in the airport technical equipment room, and a modem for connection to a central maintenance facility. ©1999 Navia Aviation AS SYSTEM DESCRIPTION 3-15 GENERAL DESCRIPTION NORMARC 7011 INSTRUMENT LANDING SYSTEM The local keyboard/display allow readings and control through an LCD display and a sevenbutton keypad. This gives access to the RMM functionality without the need for a PC. 3.9.1 RMM Access Access to the RMM system is controlled by multiple hardware and software access controls. One password is required for each access level, i.e. one password for level 1, two for level 2 and three for level 3. Optional hardware controls may inhibit writing in the upper access levels. Access level 1 • Readout of all the monitor values, warning and alarm limits. • Readout of all the maintenance values and warning limits. • Readout of all the delays. • Readout of all the monitor DDM offsets. Access level 2 • TX1 and TX2: 90/150 Hz on/off. • TX1 and TX2: morse normal, continuous, TST or off. • TX1 and TX2: test-signal 90 Hz or 150 Hz dominance on/off. • Diagnostics. Access level 3 • Settings of all the monitor warning and alarm limits. • Settings of all the maintenance warning limits. • Settings of all the delays. • Settings of all the monitor DDM offsets. 3.9.2 Local Keyboard/Display Functions Through a menu-based interface all main commands, adjustments and monitor limits are accessible from the front panel keypad and LCD display.
