3/9/2024 0 Comments Full scale vor localizer 5 25Marker beacon audio generally associated with an ILS, must be source selected by the NAV A or B audio selector switches located on the audio control panel. A 30 Hz tone will also be present in the marker beacon audio output. Proper operation of the marker beacon assembly is indicated when all three marker indicators are displayed on the EADI. The marker beacon assembly is tested automatically when the self- test is actuated and either a VOR or localizer frequency is selected. The VIR-32 will return to normal operation after approximately 15 seconds, even if the TEST switch is held. After approximately 3 seconds, the flags will go out of view, the HSI course deviation bar will deflect right approximately 2/3 of full scale and the glide slope pointer will deflect down approximately 2/3 of full scale. HSI - NAV and GS (glide slope) flags will come into view. TEST switch (NAV control unit) - Depress and hold. Also, a signal on the frequency will not interfere with the self-test. NOTE A specific frequency is not required for the test. Tuning knobs ( NAV control unit) - Select a localizer frequency. (2) ILS (Localizer and Glide Slope) Self- Test. The bearing pointers will indicate approximately a 0-degree magnetic bearing. After approximately 2 seconds the flag will go out of view, the HIS course deviation bar will approximately center, and a TO indication will appear. ![]() Course knob (HSI) - Rotate until course pointer indicates approximately 0 degrees. Double-needle bearing pointer source selector switch (display controller, fig. Single-needle bearing pointer source selector switch (display controller, fig.
