53Maneuvering speed — In aviation, maneuvering speed is the maximum speed where full, abrupt control movement in the pitch axis will result in an aerodynamic stall of the aircraft prior to exceeding the design load limit. It has been widely misunderstood that flight… …
54flutter — A vibration caused by the combined effects of the changes in pressure distribution over the surface of airfoils as the angle of attack is altered and the elastic forces set up by the distortion of the structure itself. In the worst cases, there… …
55load factor — i. The ratio of a specified load to the total weight of the aircraft. The specified load is expressed in terms of aerodynamic forces or ground or water reaction. Aerodynamically, it is the ratio of the total lift to the weight. The load factor is …
