AUTOPILOT COUPLED OPERATION
The KLN 89B may be coupled to the KAP 140 autopilot by first
selecting GPS on the NA VlGPS switch. Manual selection of the
desired track on the pilot's DG heading bug is required to provide
course datum to the KAP 140 autopilot. (Frequent course datum
changes may be necessary, such as in the case of flying a DME
arc.) The autopilot approach mode (APR) should be used when
conducting a coupled GPS approach.
NOTE
Select HOG mode for DME arc intercepts. NAV or APR
coupled DME arc intercepts can result in excessive
overshoots (aggravated by high ground speeds and/or
intercepts from inside the arc) .
