s in Equation (5a), if =0.400. h is negative if altitude is lost and positive if altitude is gained. Figure 6 is a working diagram based on Equation (6) and the assumption that T = 0 when V=2Vm. This diagram shows how the high speed is affected by a failure to maintain a true horizontal flight path… … Change in maximum speed, per cent Fig. 6.—Effect of a slight inclination of the flight path on the maximum speed of airplanes. The value of (L/D) at high speed may readily be determined for any airplane for which the maximum horizontal velocity Vm} brake horsepower (B.HP.), propeller efficiency i??…
