초록

The takeoff weight of an aircraft is computed from measures of the thrust of the engines and the forward acceleration of the aircraft detected over a time period when such acceleration is at a maximum following brake release on the runway. A major variable that must be considered is the coefficient of rolling friction of the landing gear of the particular aircraft involved and other factors inducing ground roll drag. The present invention calculated this variable as a function of engine thrust and manifest weight for each takeoff of the aircraft and upda...
