Thank you for the feedback. I will explain a bit more......
Our Club has bought (about £7k) a sim with projector etc. to give a facility when our weather is not good enough to fly. The running costs should not be high (electrics, projector bulbs, upgrades, etc) but we would like EVERYONE to get the benefit.
I think much of the benefit will be using it with instruction - even if it can't be logged it should help people to learn.
The question is what is reasonable to charge:-
A) for the use of the sim (I thought £25 per hour or £100 annually for unlimited use.
B) for the instructor. They are spending the time with the student and although it cannot be logged they should be paid. Some of our instructors think FOC, some £10 per hour, some full charge £25 - £30.
