An airplane with a mean-aerodynamic chord of 6ft. when fully ‘loaded’ with 100 passengers, each carrying 20lb baggage, has a static margin of 0.15. the total weight of the aircraft is 20,000lb. determine the change in the static margin if the each passenger carries an additional 20lb of baggage. make the following assumptions: the total baggage is treated as point-mass and is always located at 24ft. behind the neutral point; the only ‘extra’ weight is the additional baggage.
