- A fixed radius turn is defined differently in en-route and on terminal procedures. In the former, which is known as a fixed radius transition (FRT), a fixed radius value is associated with a waypoint, and the area navigation system is required to fly by that waypoint using the same turn radius regardless of the aircraft ground speed. In the latter case, the ground track is defined in the database with a waypoint at the start and end of the turn and the leg type specified as a radius to fix (RF) leg. In both cases the turn is a fixed circular track over the ground with tangential inbound and outbound legs. The area navigation system monitors cross-track error during the turn and provides guidance to maintain the circular track. RF and FRT functionality are not available on many older RNAV systems.
