It is usually quoted as a percentage of the Mean Aerodynamic Chord.
3.
For all tests, the center of gravity of the model was at either 14.5 % of Mean Aerodynamic Chord ( MAC ) or 25.5 % of MAC.
4.
The OPTINS Namelist defines the reference parameters for the aircraft . The theoretical wing area, mean aerodynamic chord, and wing span are input along with a parameter defining the surface roughness of the aircraft.
5.
In aircraft analysis, static margin is defined as the distance between the center of gravity and the neutral point of the aircraft, expressed as a percentage of the mean aerodynamic chord of the wing.
6.
In larger aircraft, weight and balance is often expressed as a percentage of mean aerodynamic chord, or MAC . For example, assume the leading edge of the MAC is 62 inches aft of the datum.
7.
Staff of the Department of Civil Aviation calculated the most likely position of the centre of gravity on the fatal flight and found it was about 3.3 % of Mean Aerodynamic Chord behind the rear limit . { { # tag : ref | The position of passengers and cargo was not known precisely.
8.
The Chief Pilot of " Queensland Airlines " told the inquest he did not believe the accident was caused by incorrect loading of the aircraft . He said the load sheet showed the aircraft's centre of gravity was at 39.2 % of Mean Aerodynamic Chord and therefore only slightly outside the approved limit.
9.
If a general MAC is not given but a LeMAC ( leading edge mean aerodynamic chord ) and a TeMAC ( trailing edge mean aerodynamic chord ) are given ( both of which would be referenced as an arm measured out from the datum line ) then your MAC can be found by finding the difference between your LeMAC and your TeMAC.
10.
If a general MAC is not given but a LeMAC ( leading edge mean aerodynamic chord ) and a TeMAC ( trailing edge mean aerodynamic chord ) are given ( both of which would be referenced as an arm measured out from the datum line ) then your MAC can be found by finding the difference between your LeMAC and your TeMAC.
