Abstract:
1. A method comprising: receiving a strut length and a weight for each of respective ones of a first plurality of gears of a first aircraft; for each one of the first plurality of gears of the first aircraft, determining an arm length based on the respective received strut length and a relationship between strut length and arm length for a respective corresponding gear of a second aircraft having a second plurality of gears corresponding in a one to one fashion to the first plurality of gears; determining a total moment of gravity of the first aircraft based on the weight for each of respective ones of the first plurality of gears, an attitude of the first aircraft, the first plurality of determined arm lengths, and a relationship between the center of gravity of the second aircraft and respective arm lengths for each of the second plurality of gears of the second aircraft; determining a center of gravity based on the total moment; and determining a mean aerodynamic chord of the first aircraft based on the first plurality of determined arm lengths and a relationship between the center of gravity of the second aircraft and respective arm lengths for each of the second plurality of gears of the second aircraft.
