T-6B PRIMARY INSTRUMENT NAVIGATION CHAPTER NINE
Vector onto Base: “Navy 123, fly heading 040.”
2. Slow toward 150 KIAS.
a. Upon making the turn to base, set 10-25% torque, allow the aircraft to slow. If a
descent or more rapid deceleration is required, a lower power setting or the use of the
speed brake may be needed.
b. Descend when directed by ATC.
Dogleg: On a dogleg to final, ATC will normally give clearance for the approach. Most
clearances follow a standard format. For example:
“Navy 123, fly heading 090, maintain 2000’ until established, cleared for the ILS
Runway 13 Approach at Corpus Christi International.”
On final:
3. As the CDI comes alive, turn onto final in order to capture the inbound course.
4. When established on final and within 5 NM of the FAF, configure to BAC.
Methods for determining when within 5 NM of the FAF
a. DME (not all ILS approaches provide DME)
b. GPS waypoint
c. Established at the published glideslope intercept altitude and the glideslope indication
is “alive” (green diamond starts to move down from the top of the glideslope case).
d. Controller radar identification
Alternate Method: Set descent power (24%) prior to configuring to BAC, configure to BAC
based on glidslope intercept (1 ½ to 1 dot). This will allow the pilot to make few and small
power changes from the final approach fix in.
5. At glideslope intercept, set power to 24% and descend on glideslope.
NOTE
In the case of a strong headwind/tailwind, more/less power may be
required.
6. Corrections for glideslope should be made with power; corrections for airspeed should be
made with pitch attitude. Of course, these two performance indicators affect each other. For
example, if below glide slope by a half dot and 10 KIAS fast, the proper correction would be to
trim nose up until on speed while crosschecking glideslope.
