What reading level is The Airplane a Practical Discussion of the Principles of Airplane Flight book?
To quickly assess the difficulty of the text, read a short excerpt:
Fig. 87 shows the distribution of pressure on the two planes of a biplane. It will be noted that the negative pressure on the top surface of the lower plane is much less than the corresponding nega- tive pressure on the top surface of the upper plane. This of course means a decrease in lift. This decrease may be made less (i) by increasing the gap between the planes; (2) by giving the planes a stagger so that the upper plane is in advance of the lower, as in Fig. 88; and (3) by increasing the a...spect ratio and thus decreasing the chord.
Fig. 87. Distribution of pressure on a biplane. Negative pressure on upper surface of lower wing is much reduced by interference with the upper wing.

On account of the interference between the planes of a biplane, both lift and L fD ratio are reduced. This reduction becomes less as the gap is increased, as shown by the following table from National Physical Laboratory data for dn inci- dence of 6; little is gained, however, by making the gap greater than the chord.
