Sozjot, thanks for the tip. Tried it today tho' and the roof mounted airconditioning unit stopped (and when I looked back later all the tyres were gone)
Seriously though, we wouldn't normally leave the brake on "park" after stopping the show as in our case the heat goes into the tail rotor shaft and main gearbox. However, if there's a very strong wind blowing we might choose to re-apply it.
