So exactly what numbers should we stick to for our category D aircraft?
800-2, no lower than 800aal, until in a position to begin a
normal descent for landing, and...no more than two miles from the runway (threshold) of intending landing, during the circling maneuver.
This is precisely what the FAA inspector expects to see during a type check in the category D airplane, or simulator.
It's all in the FAA Inspectors Handbook.
Call in at an FAA Flight Standards District Office if you would like to see for yourself.
