Now the higher the aspect ratio the greater should be the efficiency. The aspect ratio of the planes was six to one, instead of about three to one, as in their second glider. The War in the Air; Vol. 1 Walter Raleigh. An aspect ratio of 10:1 or even 12:1 should be used if possible. Scientists call this proportion of the spread to the depth the aspect ratio of planes. This is a very important consideration in the designing of an aeroplane, because aspect ratio is a factor in the speed.
