The perils of PIO;

Wind Tunnel

Its an age-old duality: stability versus maneuverability. Many factors go into developing and building any aircraft, and the designers choices will affect a pilots workload, for good or ill. Among the topics discussed are trim, pitch stability and yaw stability;

Wind Tunnel

The author discusses the theory and effect of constant-speed propellers on piston-engine airplane performance, and compares fixed-pitch versus constant-speed props, effect on thrust HP and propulsion, the comprises involved in choosing a prop, how props perform in various conditions and phases of flight, how variable-pitch props work, and why a constant-speed prop is the best choice for high-performance aircraft.
