On a recurrent S76 simulator course, 36 minutes gets you to the point of having the engines running and launching off on your first traffic pattern. We do cover all the engine starting issues during that 36 minutes. You might be surprised how many students leave an engine running without oil pressure, until it doesn't want to run any more. Reset. Try again. The economics of that learning point in the simulator alone are far more economical than making the same mistake in your real helicopter.
