FIG 5

−4−10

TAA with Left and Right Base Areas Eliminated

7.

Just as the underlying “T” approach proce-

dure may be modified in shape, the TAA may contain

modifications to the defined area shapes and sizes.

Some areas may even be eliminated, with other areas

expanded as needed. FIG 5−4−10 is an example of a

design limitation where a course reversal is necessary

when approaching the IF (IAF) from certain

directions due to the amount of turn required at the IF

(IAF). Design criteria require a course reversal

whenever this turn exceeds 120 degrees. In this

generalized example, pilots approaching on a bearing

TO the IF (IAF) from 300

_ clockwise through 060_

are expected to execute a course reversal. The term

“NoPT” will be annotated on the boundary of the

TAA icon for the other portion of the TAA.
