This advisory circular (AC) provides guidance for the design and methods of compliance for installed equipment on transport airplanes intended for use by the flightcrew. The guidance provided by this AC is intended to minimize the occurrence of design-related errors by the flightcrew and to enable the flightcrew to detect and manage errors that do occur. This AC provides recommendations for the design and evaluation of controls, displays, system behavior, and system integration that are all part of human factors considerations.

a. This Advisory Circular (AC) publishes needed changes to the existing AC material as a
result of a safety-focused study.

b. This change revises existing material in 9 sections.

c. The change number and the date of the changed material are shown at the top of each
page. The vertical lines in the right or left margin indicates the beginning and end of each change.
Pages that have different page numbers, but no text changes, will retain the previous heading
information.

d. This AC does not change regulatory requirements and does not authorize changes in, or
deviations from, regulatory requirements. This AC establishes an acceptable means, but not the
only means, of compliance. Since the guidance material presented in this AC is not regulatory,
terms having a mandatory definition, such as “shall” and “must,” etc., as used in this AC, apply
either to the reiteration of a regulation itself, or to an applicant who chooses to follow a prescribed method of compliance without deviation.
