Operation with the engine at maximum boost should be limited to
•  prop at fine to prevent overstressing the engine.
•  prop at course to prevent overstressing the engine.
•  prop at windmill to prevent overstressing the engine.

Storklubba asking:
•  While the question and answer is not wrong, the wording seems ambigious. "Maximum boost" is not a very technical term, and a simple (overspeed) clarification behind overstressing would be good. When i read this question i think that maximum boost means maximum power, and with the propeller at coarse you would be extracting more power from the engine therefore possibly "overstressing" it. I offcourse understand the answer they are looking for is coursing off the blade to not overspeed the engine and prop at high power. Am i missing something?
