T-6A INSTRUMENT NAVIGATION
IAF that may or may not be aligned with the FAC. These approaches sometimes have IAFs
located on the airway (including IAFs located on an arc) to simplify the transition from the
enroute phase to the terminal phase of flight without having to execute a procedure turn type
A straight-in procedure does not mean the approach must be
completed with a straight-in landing or made to straight-in landing
Generally, there are 2 differences in straight-in approaches:
Approaches that have the IAF aligned with the FAC (Figure 5-9).
2. Approaches that do not have the IAF aligned with the FAC, or an IAF used on an airway to
feed aircraft directly to the FAF without executing a procedure turn (Figure 5-16). The term
NoPT designated along a track arrow (thick arrow), originating from an enroute feeder fix
(Figure 5-15) or a feeder NAVAID identified as IAF designates the use of straight-in procedures.
The absence of the NoPT designation at the enroute feeder fix or
IAF for a feeder NAVAID indicates the feeder fix or NAVAID is
solely used to direct the aircraft to an IAF along a designated track
and altitude. If cleared for an approach while tracking inbound to
the IAF from a feeder fix (thin arrow, NOT designated NoPT or
IAF), you may descend to the altitude depicted along the feeder or
IAF crossing altitude whichever is higher. Upon arrival at the IAF,
perform the appropriate approach procedures. Straight-in
approaches may display an arrival holding pattern at the IAF.
TACAN or VOR/DME is usually required since the IAF, stepdown
fixes, and FAF is determined by DME.
The following procedures assume you arrive at the IAF, MIMIM, at normal cruise airspeed (no
prior holding), at 3000 feet, and are cleared for the STARKVILLE/OKTIBBEHA VOR-B.
At the IAF, execute the 6 Ts:
TIME. Not required.
TURN. Direct a turn in the shortest direction to intercept the initial approach course.
