CHAPTER 3 AVIONICS

TM 55-6930-212-10 CHAPTER 3 AVIONICS 3-1. GENERAL. 3-2. Avionics equipment is simulated under computer control, using actual aircraft panel hardware, backed up by applicable analog and digital processing and driver circuitry. Operation of most panel controls and indicators is simulated to show actual equipment functions. (Table 3-1 lists the avionics systems simulated.) Table 3-1. Avionics Equipment Simulated Nomenclature Type of system AN/APN-209 Radar Altimeter AN/ASN-128 Doppler Navigation Set AN/ARC-102 HF Radio Set AN/ASN-43 Gyromagnetic Compass Set C-6533/ARC Interphone AN/ARC-186(2) VHF AM/FM Comm and Homing AN/ARC-164 UHF Comm AN/ARN-89 LF-ADF AN/ARN-123 VHF NAV, ILS, and Marker Beacons AN/APX-100 Transponder System (IFF not simulated) AN/APR-39 Radar Warning Set AN/ALQ-156 Missile Detector Set M-130 Flare Dispenser 3-3. COMMUNICATIONS EQUIPMENT . 3-4. During training, the instructor can communicate with or monitor the trainees by using the appropriate IOS controls: a. The RADIO OVERRIDE control permits communication from instructor to trainee no matter how the radio control is set. b. The STUD MON control permits the instructor to monitor all trainee conversation no matter how the radio control is set. c. The VHF, COMM/NAV, FM, and UHF controls permit the instructor to act as the ground communications transmitter, using the trainee receiver. Since no line-of-sight (LOS) or range limit is applied to COMM networks, the instructor must check the appropriateness of the frequency selected before transmitting. d. The ICS control permits the instructor to communicate over the simulated aircraft ICS network when performing flight engineer functions. e. The telephone intercom connects the IOS with the computer room and the pump room. 3-1/(3-2 blank)
