T-6A INSTRUMENT NAVIGATION
The pilot should not descend below the MDA prior to reaching the
VDP and acquiring the necessary visual reference
Slowing to 120 KIAS and/or transitioning to BAC when more than 4 NM from the FAF.
2. Failure to direct the transition to BAC and/or completing the Before Landing Checklist
prior to the FAF.
Failure to make altitude warnings.
Failure to provide navigation inputs to the IP to maintain FAC.
Not making necessary inputs to the IP to maintain the aircraft at MDA.
Failure to ask the IP if he requires a missed approach review.
Failure to report at the MAP and/or direct the missed approach, when required.
RADAR VECTORS TO FINAL
Radar vectors to FAC is a procedure used by Approach Control to increase the arrival rate of
aircraft at airports and to establish aircraft on the FAC through the most expeditious routes
consistent with traffic situations. This approach is flown at 200 KIAS. When being radar
vectored, you more than likely will not join the approach at the IAF.
Although this routing does expedite arrival at your destination, it has one characteristic of which
you should be aware - the lack of published minimum altitudes until joining a segment of the
published approach. Approach Control has the responsibility for ensuring terrain clearance
while vectoring you for the approach. This is done through the use of Minimum Vectoring
Altitude (MVA) charts superimposed on radar displays. However, the pilot who wishes to
double-check the controller must depend largely upon the MSA published on the approach plate
and a constant awareness of his own position. Keep in mind, however, the MVA and the MSA
will not necessarily be the same altitude.
Good sense dictates you never fully relinquish the responsibility for terrain clearance to an
outside agency. Maintain geographic positional awareness and cross-check terrain clearance
altitude by using all available radio NAVAIDs. Never blindly follow vectors from a controller!
Be aware of what lies ahead on your assigned heading. If in doubt as to the appropriateness of a
given instruction, make an inquiry.
A request for radar vectors to the FAC may be initiated, or may be issued by Approach Control
with the aircrew's consent.
