then pressing the NAV GPS button on the GPS-NAV
CONTROL box located above the Attitude Indicator and
then pressing NAV on the autopilot.
The 1/2 BK function should be used when desired to prevent
excessive banking during tracking operations, especially
when close to a VOR as in station passage. The autopilot
automatically utilizes this function once established on a
LOC course in both NAV and APR modes, although the
1/2 BK button will not be illuminated.
