1. The fixed-pitch propeller is used when low weight, simplicity, and low cost are desired and is ideal for neither climb nor cruise.
2. Constant speed propellers:
3. A feathering propeller is a constant-speed unit that can rotate the blades until they are nearly aligned with the relative wind.
4. Constant speed propellers:
5. Nicks and scratches on the propeller blade less than 1/8 inch deep are not significant enough to weaken the blade and maintenance can be deferred.
6. The best way to reposition the airplane when it is parked is to:
7. The root cause of mechanically induced accidents is almost always neglect.
8. A governor failure on either a multi- or single-engine aircraft will cause overspeed.
9. In the unfortunate event of a gear-up landing, at the first sound of the prop hitting the runway, the pilot should:
10. Propellers must be overhauled:
