3.8.8 Flight Check
CAUTION
Be sure to check all aircraft control movements before flight is attempted
to insure that the wiring harness does not touch any moving part. Verify
proper operation of the marker beacon during a flight test under VFR
conditions.
Perform a flight test after installing the unit to ensure satisfactory performance of the audio and marker
beacon receiver functions. Verify proper operation of the marker lamps and marker audio, including the
marker audio mute function. Check proper operation of the sensitivity selection, using the SENS key, by
flying towards the outer marker (OM) position initially using HI sensitivity. When the OM audio is just
barely audible in the headset, switching to LO sensitivity should reduce or eliminate the audio.
This completes the in-aircraft post installation checkout.
