CHAPTER FIVE

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.

NOTE

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

Figure 5-17 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"...)
