Radio-Communication and ADF/VOR Systems

Radio-communication and radar antennas are installed under the forward section of the fuselage.

Note: This section differs from the original X-15 manual to conform to the operation of the radio-communication and navigation equipment available in the simulator.

The VHF, ADF and VOR radio-communication and navigation systems installed on the X-15A-2 SE addon enable the pilot to transmit and receive voice transmissions and to obtain visual course reference on the (optional) radio-magnetic indicator (RMI).

The system operates on a main channel and an auxiliary channel. During normal operation, the VHF transmitter and main receiver ("MAIN") are used with a VHF antenna for communication, and the auxiliary receiver ("AUX") is used with the ADF antenna for automatic direction finding (ADF) on the RMI. The system also provides VHF omni-directional radio range (VOR) navigation on the RMI and a second transceiver for voice transmissions.

The system has a dual power supply, which gives the equipment continuous operation if one of the power sources fails. The main power source for the system is the three-phase AC and the 28-volt DC systems, and protection is afforded by circuit breakers.
