Stall speed increases in proportion to the square root of the load factor. Thus, with a load factor of 4, an aircraft will stall at a speed which is double the normal stall speed.

The maximum endurance condition is obtained at the point of minimum power required since this would require the lowest fuel flow or battery to keep the sUAS in steady, level flight. Maximum range condition occurs where the proportion between speed and power required is greatest.

Referencing Appendix 1, Figure 2, use the following steps: 1. Enter the chart at a 30 degree angle of bank and proceed upward to the curved reference line. From the point of intersection, move to the left side of the chart and read an approximate load factor of 1.2 Gs. 2. Multiply the aircraft weight by the load factor: 33 x 1.2 = 39.6 lbs. Or, working from the table: 33 x 1.154 (load factor) = 38.1 lbs.

The manufacturer is the best source of performance data and information, if available.

The purpose of the rudder is to control yaw. Answer (B) is incorrect because the ailerons control bank. Answer (C) is incorrect because pitch is controlled by the elevator.
