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).
