Abstract

Particularly for structural purposes, it is important to obtain accurate measurements of the normal acceleration at the Center of Gravity of an aircraft. For most airliners and fighters, the g-sensors are located away from the Center of Gravity (C.G.). Theoretical mechanics shows that, depending on the distance between the g-sensor and the C.G., aircraft angular rates and accelerations will induce a difference between the actual normal acceleration at the C.G. and the normal acceleration indicated by the g-sensor. A method was devised to correct the normal acceleration indicated by the gsensor so as to obtain the actual normal acceleration at the aircraft C.G. Based on the method presented in this paper, tests were conducted on the B737-800 simulator and the corrections determined by the method were compared with the test data obtained from the simulator.
