Fuselage Center of Gravity X-Location as function of Overall Fuselage Length

The X-location of the fuselage CG are given as follows,

distances are given as a fraction of the fuselage length:

Single Engine Tractors: 0.32- 0.35

Single Engine Pusher: 0.45 - 0.48

Propeller Driven Twins: 0.38 - 0.40 (tractors on wing)

Propeller Driven Twins: 0.50 - 0.53 (pushers on wing)

Jet Transports: 0.42 - 0.45 (wing mounted engines)

Jet Transports: 0.47 - 0.50 (rear fuselage mounted engines)

Fighters: 0.45 (engines buried in the fuselage)

Note : Do not count the propeller spinner in fuselage or nacelle length!
