CS 22.777 Cockpit controls ED Decision 2003/13/RM (a) Each cockpit control must be located to provide convenient operation, and to prevent confusion and inadvertent operation. (See [AMC 22.777(a)](#_DxCrossRefBm2056272243)) (b) The controls must be located and arranged so that the pilot, when strapped in his seat, has full and unrestricted movement of each control without interference from either his clothing (including winter clothing) or from the cockpit structure. The pilot must be able to operate all the controls necessary for the safe operation of the aeroplane from the seat designated to be used for solo flying. (c) In sailplanes with dual controls it must be possible to operate the following secondary controls from each of the two pilots’ seats – (1) release mechanism; (2) air brakes; (3) wing-flaps; (4) trim; (5) opening and jettisoning device of the canopy; (6) throttle lever. (See [AMC 22.777(c)](#_DxCrossRefBm2056272242)) (d) Controls must maintain any desired position without requiring constant attention by the pilot(s), and must not tend to creep under system loads or vibration. A means of adjusting the freedom of operation of the throttle control during flight to achieve this must be provided. Controls must have adequate strength to withstand the loads without failure or excessive deflection. (See [AMC 22.777(d)](#_DxCrossRefBm2056272241))
