CHAPTER EIGHT T-6B PRIMARY INSTRUMENT NAVIGATION
Procedure. The following procedures assume that you arrived at the IAF, MINIM, and cleared
for the STARKVILLE/OKTIBBEHA VOR or GPS–B straight–in approach (Figure 8-15).
1. At the IAF (Using an enroute feeder fix that is identified as either “NO PT” or “IAF” –
such as “MINIM”):
a. TIME – Not required.
b. TURN – Turn in shortest direction to intercept the initial approach course (258º).
c. TIME – If required.
8-24 TERMINAL PROCEDURES
NOTE
When distance from the IAF to the Final Approach Fix is
excessive (i.e., more than 5 NM), cruise airspeed should be
maintained and landing configuration delayed until within 5 NM of
the FAF. If DME is not available, the time required to fly to a
point within 5 NM can be estimated at a rate of 3.0 miles per
minute if flying at 180 KIAS. In this example, approximately 6
minutes are required to proceed to a point within 5 NM of the FAF.
(24 – 5 = 19 NM; 19 / 3 = 6+20 minutes). Timing is not required
if DME is available, but should be used as a backup in case DME
fails.
d. TRANSITION
i. If a descent is required, establish the aircraft on course, and then use terminal
descent procedures to descend to the altitude specified (1900’) and level-off at
normal cruise airspeed.
When within 5 miles of the FAF:
ii. Make a level or descending transition to BAC.
e. TWIST
i. Twist the initial approach course (IAC) into the CDI (258º).
ii Turn to intercept the initial approach course. Track inbound to the FAF.
f. TALK – Give the appropriate voice report if required.
2. Comply with any altitude restrictions on the approach.
3. Once established inbound, comply with the remainder of the Low Altitude Instrument
Approach Procedures.
