The way I was told is, the pilot/PUT agrees with the instructor what the training flight will consist of ie: PFL, stall practice, general handling/spin recovery/avoidance, zone transit radio procedures, navigation, etc. If the pilot wanted an hour on touch & go practice into a short grass strip in a tailwheel a/c then a suitably qualified instructor would be required.
The main thing here is that the content of the training flight is up to the pilot not the instructor. In this case I opted to let the instructor decide, general handling, PFL, stall etc.
