MAC
Mean Aerodynamic Chord
MACH NUMBER
Ratio of airspeed to the local speed of sound (Mach 1 is the speed of sound under current atmospheric conditions); Symbols: M; ...
MAC - Military Airlift Command (USAF).
MACH NUMBER - Named after the Austrian physicist Ernst Mach, a means of recording the speed of a body as a ratio of the speed of sound in the same ambient conditions.
The MAC of an elliptical wing is 85% of the root chord and is located at 53% of
the half wingspan from the root chord.
The AC location for biplanes with positive stagger (top wing ahead of the bottom
wing), is found according to the drawing below.

Mean Aerodynamic Chord (MAC) A specific chord line of a tapered wing. At the mean aerodynamic chord, the center of pressure has the same aerodynamic force, position, and area as it does on the rest of the wing.
in percent of MAC. Let us assume that the weight and balance calculations have found the C.G. to be 66 inches aft of the balance datum line and the leading edge of the MAC to be 55 inches aft of the same reference (Fig. 3). The C.G.
* The area of a wing is the product of the wing span and the Mean Aerodynamic Chord (MAC). The mean aerodynamic chord is an imaginary chord line that is derived from the length of the chord line at various locations of the wing.
