Remember the mantra Gerry "Pitch up, throttle back" When increasing power advance the pitch lever first When reducing power throttle lever first. The object of the excercise is always to avoid overspeeding the engine, so adding power, you need to give the engine more work to do by coarsening the pitch, before advanceing the throttle (adding energy) Similarly to reduce power, (top of climb) you need to reduce the energy input before giving the engine less work to do. Some VP aircraft like the 182 I have flown on occasion you cannot overspeed the engine, on others it is all too easy. No doubt the Maestro will have a lot more to add about the whys and wherefores.. :-)) Peter
