Abstract

PURPOSE: To correctly correct effects on airframe characteristics during flight by determining a position of a center of gravity of an airframe during flight based on airframe gravity center change quantity by in-tank fuel condition change, and airframe gravity center change quantity based on a dropping or throwing signal for articles loaded on the airframe. CONSTITUTION: As acceleration is generated by motion of an airframe, a liquid level signal form a liquid level detector 4 provided on each fuel tank is not indicating correct fuel quantity. A relational expression to determine fuel quantity in a fuel tank and a center of gravity based on a form of the fuel tank, a direction of mixed force acceleration, a liquid level signal, etc., is formed and stored in a memory in a computer 13. A direction of the mixed force acceleration is operated based on outputs of an axial direction acceleration gauge 9 and a vertical direction acceleration gauge 10, and the relation expression is referred to based on result of operation and the liquid level signal to operate weight and a gravity center of each fuel tank 1. When dropping or throwing of articles loaded on the airframe is detected by a detector 11, a position of a center of gravity of the whole airframe is operated, and result of operation is supplied to a flight control system.
