- Summary
-
A flight investigation was conducted to define the minimum flying speed for a large, subsonic jet transport by using three techniques: (1) the Federal Aviation Regulations (FAR) Part 25 demonstration technique; (2) a flight-path 1-g-break technique; and (3) a constantrate- of-climb technique. The effect of thrust on minimum speed is analyzed. Results indicate that the flight-path 1-g-break technique was the best overall technique. The constant-rate-of-climb technique, or minimum level -flight speed, though highly affected by the deceleration dynamics of the maneuver, was found to be an acceptable alternate for the 1-g-break technique. The FAR demonstration technique, when analyzed by two current analysis methods, was found to yield the least conservative results. However, if the analysis were based on actual airplane maximum lift capability, the technique would yield acceptable results.--P. [i].
