Determine the aspect ratio of a wing with the following dimensions.

Span: 56 ft
Maximum wing thickness: 6 inches
Mean wing thickness: 5 inches
Mean chord: 7 ft

  • A

    8

  • B

    9.3

  • C

    11.2

  • D

    134.4

The Aspect Ratio (AR) describes how long a wing is relative to its chord. Mathematically this is:

  • AR = b/c

Where:

  • b: the wingspan
  • c: the average chord

In this case, AR = 56 ÷ 7 = 8
