29 Φεβ 2016 · The two primary ways that weight and balance measurements are determined are by physically weighing the aircraft and by mathematically calculating based on additions or subtractions to the previous weight. The former is performed by maintenance personnel and forms the empty weight and CG for any given aircraft.
The center of gravity (CG) of an aircraft is the point over which the aircraft would balance. [1] Its position is calculated after supporting the aircraft on at least two sets of weighing scales or load cells and noting the weight shown on each set of scales or load cells.
15 Ιουλ 2024 · An airplane in flight can be maneuvered by the pilot using the aerodynamic control surfaces; the elevator, rudder, or ailerons. As the control surfaces change the amount of force that each surface generates, the aircraft rotates about a point called the center of gravity.
Given the fact that none of the existing conceptual design-level cg estimation procedures has the degree of responsiveness and accuracy required for MDO applications, a new approach is formulated to provide a reliable range of cg locations that is better suited for MDO applications.
The subject of Weight and Balance covers at least four distinct procedures: weighing an aircraft, calculating its empty weight and centre of gravity (CG), establishing the worst forward and aft CG loading cases according to an appropriate design code and calculating weights and centres of gravity for an actual flight.
Procedures for the preparation and the actual weighing of an aircraft are described, as are the methods of determining the location of the empty-weight center of gravity (EWCG) relative to both the datum and the mean aerodynamic chord (MAC).
Center of Gravity (C.G.) location can have the single greatest influence on how an airplane handles in the air. Changing the C.G. can make a previously poor handling plane fly great, or turn an otherwise great airplane into a chore to fly.
