R A. MMR
R (1) External description
R (Ref. Fig. 004)
R The face of the MMR is fitted with a handle, two attaching parts, a
R TEST pushbutton switch and three LEDs. The LRU STATUS LED has two
R colors (red/green).
R The three LEDs have the following name, color and function:

R 1EFF : 051-099, 1 34-36-00Page 14 1 1 Config-2 May 01/05 1 1 1CES 1

R  - LRU STATUS (red) indicates that an internal fault is detected 
R  during the front panel self-test sequence 
R  - LRU STATUS (green) indicates that no internal fault is detected 
R  during the front panel self-test sequence 
R  - CONTROL FAIL (red) indicates that no control input is available 
R  during the test sequence. 
R  - ANT FAIL (red) indicates that a failed antenna is detected during 
R  the test sequence. 
R  The back of the MMR is equipped with one ARINC 600 size one 
R  connector, which includes three plugs: 
R  - Top Plug (TP): connection with the GPS antenna 
R  - Middle Plug (MP): service interconnection 
R  - Bottom Plug (BP): connection with the power supply circuit, and the 
R  LOC and G/S coaxial interconnections. 
R  (2) Internal description 
R  (Ref. Fig. 005) 
R  The MMR consists of four parts: 
R  - the power supply unit 
R  - the ILS receiver 
R  - the GPS receiver 
R  - the system processor unit. 
R  The primary function of the MMR is to receive and process ILS and GPS 
R  signals. The ILS receiver and the GPS receiver make up two of the 
R  subassemblies. The ILS signals, including both localizer and 
R  glideslope, are used to determine flight path deviations during 
R  precision approach and landing, and are supplied to the aircraft 
R  flight control and instrument systems. These deviations are based on 
R  radio frequency signals that the unit receives from a ground-based 
R  instrument landing system. 
R  The GPS receiver simultaneously tracks signals from up to twelve GPS 
R  satellites. The signals are processed to generate a three-dimensional 
R  position and a precise time. The receiver generates an estimate of 
R  the positional accuracy provided. An integrity alert is activated if 
R  an unannounced satellite malfunction is detected. The receiver has 
R  the capability of excluding satellites that are malfunctioning. 
R  The system processor card has the functions that follow: 
R  - output position and deviation data to other aircraft systems, 
R  - receive ILS frequency selections,
