Procedure. The following procedures assume that you arrived at the IAF, MINIM, at
normal cruise airspeed (no prior holding), and cleared for the STARKVILLE/OKTIBBEHA VOR
or GPSB straightin approach (Figure 669).
At the IAF (Using an enroute feeder fix that is identified as either "NO PT" or "IAF"
such as "MINIM"):
TIME Not required.
TURN Turn in shortest direction to intercept the initial approach course
TIME If required.
When distance from the IAF to the Final Approach Fix is excessive,
i.e., more than 5 NM, cruise airspeed should be maintained and
BAC procedure 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 2.5 miles per minute if flying at 150 knots. In
this example, approximately eight minutes are required to proceed
to a point within 5 NM of the FAF. (24 5 = 19 NM; 19 / 2.5 = 8
minutes). Timing is not required if DME is available, but should be
used as a backup in case DME fails.
If a descent is required, establish the aircraft on course (step "v") and then
use terminal descent procedures to descend to the altitude specified (1900
feet) and level off at normal cruise airspeed.
When within 5 miles of the FAF:
Make a level or descending transition to BAC.
Twist the initial approach course (IAC) into the IND350 (258º).
Turn to intercept the initial approach course. Track inbound to the FAF.
TALK Give the appropriate voice report if required.
Comply with any altitude restrictions on the approach.
