§3.115 Specific conditions.

In conditions set forth in this section, within the speeds specified, the stable slope of stick force versus speed curve shall be such that nay substantial change in speed is clearly perceptible to the pilot through a resulting change in stick force. (a) Landing. The stick force curve shall have a stable slope and the stick force shall not exceed 40 lbs. at any speed between 1.1 Vs1 and 1.3 Vs1 with: (1) Wing flaps in the landing position, (2) The landing gear extended, curve shall (3) Maximum weight, (4) Throttles closed on all engines, [(5) Airplanes of more than 6,000 pounds maximum weight trimmed at 1.4 Vs1 , and airplanes of 6,000 pounds or less maximum weight trimmed at 1.5 Vs1.] (b) Climb. The stick force curve shall have a stable slope at all speeds between 1.2 Vs1 and 1.6 Vs1 with: (1) Wing flaps retracted, (2) Landing gear retracted, (3) Maximum weight, (4) 75 percent of maximum continuous power, (5) The airplane trimmed at 1.4 Vs1. (c) Cruising. (1) Between 1.3 Vs1 and the maximum permissible speed, the stick force curve shall have a stable slope at all speeds obtainable with a stick force not in excess of 40 pounds with: (i) Landing gear retracted, (ii) Wing flaps retracted, (iii) Maximum weight, (iv) 75 percent of maximum continuous power, (v) The airplane trimmed for level flight with 75 percent of the maximum continuous power. (2) Same as subparagraph (1) of this paragraph, except that the landing gear shall be extended and the level flight trim speed need not be exceeded.
