Am I just getting old, or have the rules changed?
Departing the circuit don't you extend one leg, or climb to 500' above the circuit height and are 3NM+ away before turning contrary to the circuit direction.
This bloke flying to Benalla levelled off at 1200 MSL - with Mangalore's elevation of 450MSL - so 200' lower than he should be just for a circuit, cleared the survey aircraft and then set course for Benalla requiring 60* turn contrary to the circuit direction while still at 1200MSL and presumably, still inside the circuit area!
And the flying school tries to put it back on the survey aircraft because "he didn't call like they normally do"? How about teaching your students to communicate with non-standard aircraft instead of delaying their responses or not talking at all.
