Localizer interference
Hi All,
I have another issue with Bell 412EP. The localizer deviation bar oscillates about one bar thickness from the center. The situation is worse if ILS approach is made to cross-wind and the autopilot turns the RC to compensate the wind (the RC is approaching the runway nose slightly sideways) .
The VOR/LOC antenna is in the tailboom ("the thick handles beside both sides"). Would this be issue with the antenna as the loc deviation oscilaltion seem to be strong enough that the autopilot starts to make corrections in roll channel causing the whole rotorcraft to swing. The autopilot is SPZ-7600 (3-axis & dual FD) and the navigation radio is Garmin GTN750. Antennas are original from 1996.
