nd 150 miles per hour was found. It was In order to obtain these dive angles in the flight tests, assumed that the correction for the diving conditions a curve of the elevation of the sun against time was plotted, and a pointer on the dive-angle indicator was was also 2 percent. From data obtained… … Figure 1.—The FGC-4 airplane. was to be started. Continuous records of indicated air The method employed consisted of deducting the speed, engine speed, air temperature, and barometric calculated induced drag from the total drag, which had pressure were taken throughout all the dives. been…
