- What does %MAC mean? - Aviation Stack Exchange
A document said that the optimum CG position is from 13% MAC to 33% MAC I'd like to know what that means, and what would this look like on an actual plane
- How does a commercial airliner measure its weight mass? - Aviation . . .
The MAC is a portion of the wing, delimited by LeMAC (leading, 0%) and TeMAC (trailing, 100%) The CG must be located in the MAC In large aircraft, center of gravity limitations and the actual center of gravity are often expressed in terms of %MAC (on the roll axis, similar limits exist on the two other axis)

Pilots, dispatchers or load masters will calculate the weight and balance with respect to the aircraft datum Unfortunately, we need to point the numbers are in reference to (datum) to be changed to the front of the wing called leading edge mean aerodynamic chord (LEMAC) There is also a trailing edge mean aerodynamic chord (TEMAC) that is calculated TEMAC - LEMAC = Wing width
- weight and balance - Aviation Stack Exchange
Find the position of the centre of gravity in % of the MAC (mean aerodynamic chord) if the distance from the datum to the LEMC (leading edge of mean chord) is 13 meters, the distance to the TEMC (
- What is the physical meaning of Mean Aerodynamic Chord?
The mean aerodynamic chord is only identical to the mean chord for rectangular wings For tapered wings it is slightly longer Why? Because the mean aerodynamic chord is the mean chord of a rectangular wing that has the same pitch characteristics as the "real" wing Pitch characteristics need to include pitch damping, and pitch damping grows with the square of the local chord That is why the
- aircraft design - Aviation Stack Exchange
The rest of the airframe would need to be factored into computing the aircraft center of gravity and its relationship to your spar, but generally 25% LEMAC, (Leading Edge of the Mean Aerodynamic Chord) is a good starting point As a point of reference, the acceptable CG range of the C-130 Hercules is 15 to 30% LEMAC
- weight and balance - Aviation Stack Exchange
With a swept wing aircraft (specifically a MiG-25 I am modelling) where is the root chord taken from to calculate the location of CG? Is it the root chord of the wing (where it attaches to the fuse
- What is the loading diagram for a C-130J? - Aviation Stack Exchange
For a quick answer though, you are mixing up two variants of the -J The -30 is a stretch, and those are the numbers you found Flight station 737 is at the ramp on a short model The -30 is 200" longer however The mean aerodynamic chord of c-130 any variant or model is 164 5" Leading edge to MAC of a stubble is 487 4" -30 LEMAC is 687 4"
