Course Reversals (Procedure Turn)
If a course reversal is required, the pilot must set the required outbound course
on the HSI and select HOLD mode with the GPS SEQ switch prior to crossing
the FAF outbound. The GNC300 will then provide the appropriate course
guidance outbound from the fix. Upon starting the course reversal (procedure
turn outbound), the pilot must set the charted inbound approach course on the
HSI. When intercepting the approach course inbound, the pilot must set the
GPS SEQ switch to AUTO. The GNC300 will provide guidance inbound to the
FAF on the course which was set on the HSI at the time the GPS SEQ switch
was changed from HOLD to AUTO.
NOTE: It is important that the GPS SEQ switch be
changed from HOLD to AUTO after the HSI course
pointer is set to the inbound approach course. For GPS
approach activation to occur, the GPS SEQ switch must
be set to AUTO prior to crossing the FAF inbound.
Approach Vectoring
The approach route loaded when an approach is selected includes all of the
normal approach segments. Normally, the first approach waypoint encountered
is the IAF. If ATC is providing vectoring on the approach, any waypoint on the
approach may be manually selected as the first waypoint of use. If, for example,
ATC provides vectors to the final approach course, the FAF should be selected
as the first approach waypoint to use. When informed by ATC that you are
being provided vectors to the final approach course, select the FAF by placing
the cursor over that waypoint on the RTE page, and pressing the DIRECT TO
key followed by the ENT key. The GPS SEQ switch must be placed in the
HOLD position, and the HSI course pointer used to select the inbound final
approach course. Upon intercepting the inbound final approach course, place
the GPS SEQ switch in the AUTO position.
