Another question; I note most clubs rent out planes per hour, usually on a brakes on / brakes off basis. What is the normal situation if you want a plane for a couple of days; do you still only pay for actual flying time, or do they charge you per hour for time the aircraft is away from base as well?
As mrmum says. They might for example want to be paid for a minium of three hours on a Saturday or Sunday, whether you fly them or not, but impose no minimum on a weekday when they'd have had an idle aircraft anyway.
The only times I've taken an aircraft for a whole day from a club with a 3 hour weekend rule they haven't actually charged me for any more than the 2hr 45 flying I actually did.
