The root-mean-square values of rigid-airframe responses and tail-load responses were calculated at five flight conditions, and the behavior of these responses was observed in two autopilot modes: pitch-attitude-hold mode and altitude-control mode. It was found that pitch attitude and altitude can be controlled by the simple autopilot with acceptable or no increases in tail loads.Aerodynamic loadsnasatAtmospheric turbulencenasatAutomatic pilot (Airplanes)AirplanesHandling characteristicsAirplanesTail surfacesAerodynamic loadAerodynamic loadfastAirplanesHandling characteristicsfastAirplanesTail surfacesfastAtmospheric turbulencefastAutomatic pilot (Airplanes)fastAerodynamic loads.Atmospheric turbulence.Automatic pilot (Airplanes)AirplanesHandling characteristics.AirplanesTail surfaces.Aerodynamic load.Aerodynamic load.AirplanesHandling characteristics.AirplanesTail surfaces.Atmospheric turbulence.Automatic pilot (Airplanes)Perry Boyd1389770United States.National Aeronautics and Space Administration,Langley Research Center.ABCABCAD#OCLCEOCLCQOCLCOOCLCFOCLCQGPOBOOK9910716544203321The effects of an autopilot on airplane responses to turbulence with emphasis on tail loads3510622UNINA
