What considerations / restrictions are there for installing the KTA-870 / KMH-880 Traffic Advisory Systems on fixed landing gear aircraft?
For installation of the KTA-870 and KMH-880 systems onto aircraft with fixed landing gear, only a bottom monopole L-band antenna can be equipped. The landing gear discrete must be strapped to the retracted position. The bearing from a bottom directional antenna (KA-815) is invalidated when landing gear is extended, Therefore, the bearing of aircraft tracked with the bottom antenna is always invalidated on a fixed landing gear aircraft.
