The advantages of an in flight adjustable or a constant speed propeller are generally seen as the top speed of the aircraft increases. The increase in speed makes the difference in the desired blade pitch for takeoff and cruise greater. A fixed pitch propeller is a compromise between the two extremes. You must, however, weigh the advantages of an adjustable propeller against the cost, reliability, and any other factors that come to bare. An adjustable propeller would, in theory, give you a shorter takeoff roll, a better climb rate, and a higher cruise speed, but at what cost? Larry Flesner
