Before you do anything just ask him "Shall I do (so and so) now, sir?"!
E.g "Shall I call for taxi now?"
"Shall I take off now?"
etc - you get the drift
Then you get on the approach get very low and say "Shall I put on power now, sir"
Exasperated instructor now blows his cool and says "No mate let's crash instead!" (Expletives deleted)
Another good way to annoy your instructor is to forget everything you were taught on the previous lesson. You know the sort of thing, you did Stalling Part One last time and you are now on Stalling Part Two and you behave as though you have never heard of the HASELL checks before!
