I took off from Runway 34L at 169,800 pounds gross weight, rotated at 1.8 degrees per second, and lifted off at a pitch attitude of 6.5 degree glideslope, high density altitude, and an approach speed of 150 knots, all of which put our nominal descent rate very close to the book maximum of 1,000 ft/min.

2: What effect does high density altitude have on the efficiency of a UA propeller? Density altitude does not affect propeller efficiency. gross weight is reduced. 2: A stall occurs when the smooth airflow over the unmanned airplane’s wing is disrupted and the lift degenerates rapidly.

The POH lists landing distances for specific gross weights. Smaller aircraft may only have short field landing distances for maximum gross weight. Temperature An increase in temperature will increase the density altitude. A high density altitude decreases the performance of the engine and the wing.

Meaningful weight conservation comes from the elimination of a spar overlap a two-piece wing would require plus the one-piece design is easier to build accurately. The airfoil is a Harry Riblett shape, giving modernized flow separation on the leading edge for a soft stall yet with good lift and drag performance.
