To quickly assess the difficulty of the text, read a short excerpt:
20 further shows that when the pitch ratio is less than 0-8 the highest point of the power-plant curve lies to the left of the aeroplane curve. It only lies to the right of it when the pitch ratio is equal to or greater than 0-9. If the pitch ratio were 0-85, the highest point of the power- plant curve would just touch the aeroplane curve, and would hence correspond to normal flight. * Attention is, however, drawn to the remarks at the bottom of p. 74. 86 . FLIGHT WITHOUT FORMULA In Chapter IV.... It was shown that the highest point of the power-plant curve corresponds the propeller being supposedly well adapted to the motor to a rotational velocity of 1200 revolutions per minute, the normal number of revolutions at which it develops full power. If, there- fore, this highest point lies to the left of the aeroplane curve, the motor is turning at over 1200 revolutions per minute when the aeroplane is flying at normal speed. On the other hand, if the highest point lies to the right of the aeroplane curve, in normal flight the motor will be running at under 1200 revolutions per minute.
