- sensing oil level in the tank;
sensing acceleration of the aircraft;
sensing rates of change in orientation of the aircraft;
calculating the acceleration of the tank by a processor using sensed acceleration of the aircraft and sensed rates of change in orientation of the aircraft; and
calculating the oil quantity in the tank by compensating the sensed oil level to account for the acceleration of the tank.

Abstract
A system and method for accurately calculating the oil quantity and oil consumption rate of an aircraft engine detects the level of oil in an oil tank, calculates the oil quantity in the oil tank by compensating for the acceleration of the aircraft, as well as changes in the pitch, yaw and roll of the aircraft. The oil consumption rate of the aircraft is also calculated by calculating the oil quantity at different times, and dividing the difference in oil quantity by the difference in times. The percentage change in oil consumption of the aircraft engine is also calculated. The oil quantity and oil consumption rate can be reported during and after the aircraft'"'"'s flight.
