CS 25.1302 Installed systems and equipment for use by the flight crew ED Decision 2007/010/R (See [AMC 25.1302](#_DxCrossRefBm1709821572).) This paragraph applies to installed equipment intended for flight-crew members’ use in the operation of the aeroplane from their normally seated positions on the flight deck. This installed equipment must be shown, individually and in combination with other such equipment, to be designed so that qualified flight-crew members trained in its use can safely perform their tasks associated with its intended function by meeting the following requirements: (a) Flight deck controls must be installed to allow accomplishment of these tasks and information necessary to accomplish these tasks must be provided. (b) Flight deck controls and information intended for flight crew use must: (1) Be presented in a clear and unambiguous form, at resolution and precision appropriate to the task. (2) Be accessible and usable by the flight crew in a manner consistent with the urgency, frequency, and duration of their tasks, and (3) Enable flight crew awareness, if awareness is required for safe operation, of the effects on the aeroplane or systems resulting from flight crew actions. (c) Operationally-relevant behaviour of the installed equipment must be: (1) Predictable and unambiguous, and (2) Designed to enable the flight crew to intervene in a manner appropriate to the task. (d) To the extent practicable, installed equipment must enable the flight crew to manage errors resulting from the kinds of flight crew interactions with the equipment that can be reasonably expected in service, assuming the flight crew is acting in good faith. This sub-paragraph (d) does not apply to skill-related errors associated with manual control of the aeroplane. [Amdt 25/3]
