WING PLANE and HORIZONTAL with the aeroplane in an unbanked, level condition.

Taper ratio is the ratio of:

the root chord to the tip chord.

TR: Root Chord to TIP CHORD

The aspect ratio of the wing is:

the ratio between the WING SPAN and the MEAN GEOMETRIC CHORD.

AR is the ratio WING SPAN : MEAN GEOMETRIC CHORD.

The Mean Aerodynamic Chord (MAC) for a given wing of any planform is
