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.)

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.
