If one of my customers wants me to do something that I don't feel like doing I can say no. If I want to buy a flight from a club which they don't offer they can say no. Simple as that.
Yep absolutely right.
But you are making up rules as to them being able to dictate what goes in the revalidation flight, which they can't.
You can count ANY flight of 1hr or more as the required flight. You show me a school that will refuse a 1hr training flight where the pilot just wishes to fly in a straight line for 30 minutes out and a straight line back as PUT. The signing of the licence is a separate issue and it is not down to the examiner signing the licence to investigate the flight, they just ensure the regs have been met. Pure and simple.
