Hours charged = rotors turning?
A quick question:
As self-fly-hire and lessons are charged at an hourly rate and measured by the Hobbs meter, how is the meter driven? Is it by the rotor mast turning, or turning under power with clutch engaged?
If it's the former, then in a heli with no rotor brake, that's quite a cost. If it takes approx 4 minutes for a Schwietzer 300's rotors to stop turning, that's £3000 over the length of 150 hours training to CPL, where you're just sat doing nothing waiting to get out! Am I right?
