Abstract
An example method for in-flight determination of a gross weight of an aircraft includes causing an aircraft to perform a first flight operation defined by a first airspeed that is substantially constant and a descent rate that is substantially constant, determining the first airspeed and a first thrust that caused the aircraft to perform the first flight operation, the first thrust being substantially constant during the first flight operation, causing the aircraft to perform a second flight operation defined by a second airspeed that is substantially constant and a descent rate that is substantially constant, determining the second airspeed and a second thrust that caused the aircraft to perform the second flight operation, the second thrust being substantially constant during the second flight operation, and using the first thrust, the second thrust, the first airspeed, and the second airspeed to determine the gross weight of the aircraft.
