restrictions for the intended approach. These are listed in the

approach plates, AP1, IFR supplement, and current NOTAMs.

2. The T-6A is an Approach Category B aircraft based on

approach speed of 91 KIAS or more, but less than 121 KIAS.

CIRCLING MINIMUMS

Published circling minimums provide a 300-foot obstacle clearance when pilots remain within

the appropriate area of protection (Figure 5-21).

Pilots should remain at or above the circling altitude until the aircraft is continuously in a

position from which a descent to a landing on the intended runway can be made at a normal rate

of descent using normal maneuvers. Circling may require maneuvering at low altitude, at low

airspeed, and in marginal weather conditions. Aircrew must use sound judgment, have an in-

depth knowledge of their capabilities, and fully understand the aircraft's performance to

determine the exact circle maneuver to use. The IP should brief division of responsibilities

during circling maneuvers (i.e., the IP will keep the runway in sight and the student will monitor

instruments, especially the altimeter.)

Figures 5-22 and 5-23 illustrate suggested patterns that may be flown. Choose a pattern that best

suits the situation.
