Autopilot sentence "type B", cross-track error, bearings and heading towards destination waypoint. This is a fixed form of the APA sentence with some ambiguities removed.

Note: Some autopilots, Robertson in particular, misinterpret "bearing from origin to destination" as "bearing from present position to destination".

Example:
$GPAPB,A,A,0.10,R,N,V,V,011,M,DEST,011,M,011,M*82
