Should I write to Capt Goodwin
Apologies to bring this up again Nobby but max AOB is not necessarily 15 to 20, infact on both my current ac and my previous ac my max AOB was 45 degrees whilst in the circuit.
The limiting factor on your angle of bank used in the circuit is speed at which you will stall. This speed increases as you increase AOB and therefore load as such different types of aircraft will have different approach speeds and stall speeds. I suspect therefore that your information is specific to your type of aircraft and similar.
A much clearer explanation of this relationship is given on one of the fatal accident threads from the weekend.
What's certainly true is that if your instructor tells you that you are not to exceed 20 degrees AOB in the circuit then don't.
As pointed out, diagrams 1 and 3 are correct for military circuits. I would add that the join in 3 could be made at any point along that deadside track to fit in with traffic and expedite recovery.
