What basic equation is used in all Weight & Balance problems?
Weight(W) x Arm(A) = Moment(M)

Center of Gravity = Moment/Weight
Define Center of Gravity
The theoretical point of balance, the mass center of the aircraft.
Describe 10 performance characteristics that are adversely affected when an aircraft has been overloaded.
Higher takeoff speed
Longer takeoff run
Reduced rate & angle of climb
Lower Maximum altitude
Shorter range
Reduced cruising speed
Reduced maneuverability
Higher stalling speed
Higher landing speed
Longer landing roll
Excessive weight on nose wheel.
Distribution of pressures acting on the wing is controlled by what?
The angle of attack of the wing.
Give 4 characteristics of a forward center of gravity.
Higher stall speed
Slower cruise speed
More stable
Greater back elevator pressure.
What is the basic equation used to determine the center of gravity?
Divide Total Moments by Total Weight
∑Moments / ∑Weight
Give 3 characteristics of an aft center of gravity.
Lower stall speed
Higher cruise speed
Less stable - stall & spin recovery more difficult
If weight & balance of aircraft has changed due to change of equipment, what are the owners' responsibilities?
Must ensure maintenance personnel have made appropriate entries in aircraft records, where repairs and modifications have been made. Use Major Repairs & Alterations (FAA Form 337).
