Then the slow ship elects to do a NAVEX for a circuit
Frustrating, indeed .. and, generally, quite unnecessary.
Many years ago, I did some work on Ralph Capponi's 685. He cut out payment for the engineering in a circuit session off 17 at EN .. with the climb performance, near empty, didn't need to go outside the aerodrome boundary .. poor old Ralph in the RHS couldn't see the aerodrome most of the time.
