Approach GPSS Operation
When the autopilot is directed by GPSS, there are few
considerations when flying an approach.
·
GPSS information will not be provided after you
pass the MAP. You need to follow the directions
published on the approach plate.
·
When directed to the MAHP, use the Direct-To
function. GPSS information will now once again
be provided to the autopilot.
·
Certain waypoints within an approach may be
coded as “Fly-over” waypoints. Fly-over
waypoints must be overflown before starting your
turn to the next waypoint. A turn anticipation
curve will not be drawn for these Fly-over
waypoints. The GPSS information from your
Apollo GX will handle this automatically.
GPSS Rules
There a few rules for providing valid GPSS
information to your autopilot. Your autopilot should
indicate when GPSS information is valid/invalid.
Refer to your autopilot operating instructions for
details.
