Abstract�� To solve the stability adjustment problem of pilot-seat system after ejecting from fight plane cabin, a new electronics equipment which can measure the combined center of gravity of pilot-seat system was designed and manufactured, a new pitching-progressive measure and calculate technique was founded, and the combined center of gravity of 294 pilots were measured. It shows that the new equipment is accurate and reliable, the technique is efficient and convenient, and they are both universal. The equipment and technique have been applied in the design and manufacture of ejection seat. It is proved that the precision is improved 10 times, while the efficiency 3 times.
Keywords�� ejection seats   aircraft pilots   measurements   stability   center of gravity
