Turn anticipation will not be available when
sequencing is on Hold; for the MAP or MAHP of an
approach; or for the “flyover” waypoints in an
approach.
Wind and Turn Anticipation
The graphic Turn Anticipation curve drawn on the
map display is based on your current ground speed.
Once you enter the turn, the graphic curve is no
longer updated. You may need to increase or decrease
your standard rate turn to compensate for wind. If
your installation includes a GPSS autopilot interface,
the Apollo GX will monitor your progress throughout
the turn and send corrections to the autopilot. Wind
conditions requiring steeper than maximum bank
angles may result in overshooting the new course line.
GPSS GPS Steering (GPSS) information is provided by
your Apollo GX when setup with a properly installed
autopilot. An autopilot guided by information from
your Apollo GX will be more accurate, faster
responding, and smoother than using a CDI. GPSS
works with the Flight Plan and Turn Anticipation
features to have your avionic equipment do more of
the work for you.
Standard GPSS Operation
Operating your Apollo GX with an autopilot is
simple:
1) Select a waypoint or flight plan in the Apollo GX.
2) Select GPSS mode on the autopilot or on the
HDG/GPSS selector switch (see your autopilot
operating instructions).
3) Fly. Your Apollo GX will direct the autopilot.
