Abstract : The paper is intended to show that it is possible to obtain the more important aerodynamic coefficients from a limited number of simple flight tests, and this enables an assessment to be made of the performance and handling qualities of an aircraft at the prototype stage. The tests are limited to small movements of the aircraft and control surfaces, and the coefficients, being assumed to be constant, are functions only of Mach number. An example is discussed of the determination of the aerodynamic coefficients of an aircraft with conventional flying controls, i.e. separate ailerons, elevators and rudder. (Author)
