T-6A INSTRUMENT NAVIGATION
If the FAWP is not the Active WPT, the pilots must cycle back to
the FAWP and push "DIRECT TO" followed by "ENT."
Within the 2 NM gate, the KLN 900 verifies the aircraft's heading,
position and RAIM. If the parameters are met, the system
"activates" the approach and the CDI scale factor smoothly
changes to + 0.3 NM full deflection.
11. At the FAWP, conduct the 6 Ts and verify a green GPS annunciator.
12. Upon reaching the MAWP, if the runway is not in sight or the aircraft is not in a position to
make a safe landing, execute the MAP.
The GPS system will not automatically sequence to any waypoints
required to execute the missed approach procedure. Automatic
sequencing will cease at the MAP. If a missed approach is
required, the pilot must manually sequence the system to the
MAWP. Press the "DIRECT TO" key followed by the "ENTER"
key; the default WPT will be the MAWP defined in the procedure.
Once cleared to a holding fix, use the "DIRECT TO" function of the GPS to highlight, select and
enter the holding fix as the active waypoint in the active flight plan (FPL 0). Ensure the system
is in LEG mode and proceed direct to the fix. The LEG mode provides the direct course routing
to the active waypoint from the aircraft's present position at the time the "DIRECT TO" function
Prior to arriving at the holding fix, select OBS mode and dial in the holding course. Once at the
holding fix, enter the holding pattern using normal entry procedures. Make sure the holding fix
is still the active waypoint. If not, select (from FPL 0) and re-enter the holding fix as the active
waypoint. Selection of OBS mode prior to arriving at the holding fix is necessary in order to
disable automatic waypoint sequencing. The selection of OBS mode also allows the aircrew to
dial in the holding course on the CDI. The holding course is best visible on the SuperNAV 5
page and it is recommended the holding pattern be conducted with this page displayed on the
GPS HOLDING PROCEDURES
Ensure the holding fix is the active WPT.
Ensure LEG mode selected while proceeding enroute to the holding fix.
