T-6A INSTRUMENT NAVIGATION
1. There are different techniques for the descent to MDA. One
is to maintain a gradual descent similar to the glideslope. Another
is to descend at a higher rate and arrive at the MDA sooner. The
goal of both is to arrive at the MDA with enough time to visually
acquire the runway environment prior to getting to the MAP.
2. Some approaches have progressively lower stepdown
altitudes. Level off at each stepdown altitude until the indicated
DME point, and then continue descent until the next stepdown
altitude or MDA. Be sure you are using the correct minimums for
the runway in use. When directing a descent, student should direct
the IP to descend to the first altitude that must be maintained, then
state any additional altitude restrictions that apply.
TWIST. Set the FAC in the CDI. Intercept and track the FAC.
TALK. Give the voice report, if requested (ensure you have made any required
frequency change). Report 200 feet prior to any level off altitude and report MDA to
When not in radar contact, a voice report is required when leaving
FAF inbound on final approach (non-precision approach) or when
leaving the OM or fix used in lieu of the OM inbound on final
approach (precision approach).
Ensure the pilot levels off at the MDA. Do not allow descent below the MDA.
If the pilot descends below the MDA, direct an immediate climb to the MDA ("climb to 680
Provide heading, altitude, and airspeed inputs to the pilot as required to maintain 120 KIAS
on the FAC at the MDA.
At the MAP: Report "At the MAP" and ask your IP if the field is in sight. If the field is in
sight and the aircraft is in a position to make a safe landing, descent below the MDA is
authorized. If both conditions are not met, direct the IP to execute a missed approach.
The pilot should not descend below the MDA prior to reaching the
VDP and acquiring the necessary visual reference
