Ok
Point taken about the biz jet.
You stated that a PPL would find themself in a spiral dive. Don't think that would happen with an instructor on board. But admittadly you were thinking that he/she had no instruments. To see the instruments, they have a 2 cell maglite welded between thier head and headset frame. Not as un-comfortable as it sounds.
Patronising jibes: you did imply that i was hour building at the expense of the student. So yes, your right, not very constructive.
I am open to all ideas, hence why i teach a few things that are not strictly worded around the syllabus so that in un-usual circumstances a pilot can stay calm and get on with the job. I absolutely insist that a night student/pilot goes off with full tanks, even round the circuit. That's not listed in the syllabus anywhere. I also teach that if they are going cross country to land away, they always file an IFR flight plan. Again, not in the syllabus but a good idea.
Spinning is not compulsory in the PPL syllabus, but i still insist they have stall spin awareness and can recover from one.
I am sure that as an FI you teach the same.
