Conventions and abbreviations used in this manual are also given. 1.1Introduction This is an overview of Normarc's NM 7050 ILS marker beacons systems. 1.1.1ILS Overview A complete Instrument Landing System comprises: •A LOCALIZER SYSTEM, producing a radio course to furnish lateral guidance to the airport runway. • A GLIDE PATH SYSTEM, producing a radio course to furnish vertical guidance down the correct descent angle to the runway. • MARKER BEACONS, to provide accurate radio fixes along the approach course. The layout of a typical ILS airport installation is shown below. Figure 1-1Typical ILS airport installation 1.1.2Marker Beacons Overview The complete ILS marker beacons system comprises: • A Marker Beacon transmitter/monitor cabinet • A Marker Beacon antenna • A remote control • An Remote Maintenance Monitor (RMM) program to be installed on a PC • Optional slave panel • Optional backup battery Localizer 110 MHz Glide Path 330 MHz Marker Beacon 75MHz 3° HBK547-1 USER MANUAL 1-2 21464-5 NORMARC 7050 MARKER BEACON GENERAL INFORMATION©1999 Navia Aviation AS Figure 1-2 Marker beacon block diagram 1.1.3Marker Beacons Description The marker beacons are located vertically beneath the localizer course line at distance 150m (inner marker), 1km (middle marker) and 7km (outer marker) from the runway threshold. The beacons radiate a 75MHz radio signal with an audio Morse code. The Morse code and modulation frequency differ for the outer, middle and inner marker. Outer marker transmits dash code 400Hz, middle marker transmits dash dot code 1300Hz and inner marker dot code 3000Hz. 1.2Product Type Numbers The Normarc product numbering system is based on the following three levels: •System • Assembly • Module Systems have type numbers starting with NM, for example NM7050. Systems consist of assemblies, modules and parts. Assemblies have type numbers consisting of three letters, a three- or four- digit number and a letter, for example CAA 1370A. CAA is an abbreviation of CA binet Assembly, 1370 is a run- ning number, and the last letter is the variant designator. Assemblies can consist of assem- blies, modules and parts.

MO is an abbreviation of MO nitor, 1374 is a running number, and the last letter is the variant designator. Modules consist of parts. 1.3Abbreviations AC:Alternating Current ADC:Analog to Digital Converter AGC:Automatic Gain Control CPU:Central Processing Unit DAC:Digital to Analog Converter DC:Direct Current DM:Depth of Modulation EEPROM:Electrically Erasable Programmable Read Only Memory EMC:Electro Magnetic Compatibility EMI:Electro Magnetic Interference EPROM:Erasable Programmable Read Only Memory FIFO:First In First Out FPGA:Field Programmable Gate Array I/F:Inter Face ILS:Instrument Landing System IM:Inner Marker LED:Light Emitting Diode LF:Low Frequency LRU:Line Replaceable Unit MCU:Monitor Combiner Unit MM:Middle Marker NAV:NAVigation signals NF:Near Field OM:Outer Marker PC:Personal Computer RAM:Random Access Memory RF:Radio Frequency RMM:Remote Maintenance Monitor RMS:Remote Monitoring System ROM:Read Only Memory RTC:Real Time Clock SC:Station Control SRAM:Static Random Access Memory STB:STandBy SW:Soft Ware TX:Transmitter USER MANUAL 1-4 21464-5 NORMARC 7050 MARKER BEACON GENERAL INFORMATION©1999 Navia Aviation AS ©1999 Navia Aviation AS21464-5Physical organisation USER MANUALNORMARC 7050 MARKER BEACON 2-1 2Physical organisation This chapter describes the physical outline of the NM 7050 2.1Configurations 2.1.1Module and Assembly Location The figures on the following pages show the locations of the modules in the main cabinet.

It is essential for the MB to function, that the cards are placed in these locations. If your MB is configured with only one plugin board of each type, they must be placed in the number one locations. The backplane is however , marked with notifications of where each boards place is.. ΤThe electronic devices inside NM 7050 are sensitive to Electro Static Discharge (ESD).
