CS 25.1302 Installed systems and equipment for use by the flight crew
ED Decision 2007/010/R
(See AMC 25.1302.)
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.
