T-6A INSTRUMENT NAVIGATION
1. Leading the Turn at the IAF. When clearance for the approach is issued, ATC expects an
immediate turn in the shortest direction to intercept the initial approach course upon reaching the
IAF. Clearance for the approach does not include clearance for the holding airspace. However,
normal lead points may be used to intercept the course (Case A, Figure 5-17). If you are
approaching the IAF on an acute angle (Case B, Figure 5-17), you may need to maneuver the
aircraft for a more favorable alignment prior to starting the approach.
In the terminal area, all turns onto or off of arcs and inside the IAF
shall be led in order to maintain the desired track/course.
Proceed direct to IAF

Proceed direct to the IAF

If "hitting the IAF" at an acute angle, with a requirement for over a 90° turn onto the initial
approach course or arc, maneuvering airspace is recommended.
Maneuvering airspace is airspace used to allow the aircraft to provide favorable alignment onto
the initial and intermediate approach course.
If maneuvering is desired, first obtain clearance from ATC since clearance for the approach
does not include clearance for use of holding or maneuvering airspace. ATC may assign an area
and boundary for the maneuver (i.e., "Maneuver NW of IAF between 10-12 DME"...)
