Minimum Performance Standard for Airborne Multipurpose Electronic Displays AS8034C

This SAE Aerospace Standard (AS) specifies minimum performance standards for all types of electronic displays and electronic display systems that are intended for use in the flight deck by the flight crew in all 14 CFR Part 23, 25, 27, and 29 aircraft. The requirements and recommendations in this document are intended to apply to all installed electronic displays and electronic display systems including those that have a touch screen interface within the flight deck, regardless of intended function, criticality, or location within the flight deck, but may also be used for non-installed electronic displays. This document provides baseline requirements and recommendations (see 2.3 for definitions of “shall” and “should”). This document primarily addresses hardware requirements, such as electrical, mechanical, optical, and environmental. It does not address system specific functions. It does not contain an exhaustive or comprehensive list of requirements for specific systems or functions, such as TCAS, ADS-B, GPS, weather, or shared display considerations (e.g., when should alerts be inhibited on a display system that simultaneously depicts navigation data integrated with terrain data or traffic alerting). This document is intended to be used in combination with other guidance material contained in current system specific, TSOs, Advisory Circulars (ACs), and other Federal Aviation Administration (FAA)-approved guidance material.

The requirements and recommendations in this document are intended to apply to, but are not limited to, the following types of display functions:

Electronic displays can include one or more of the following interconnected components. Other configurations are possible.

Head up displays are out of scope for this document. The minimum performance standards for head up displays are provided in AS8055A.

NOTE: This document is expected to be used by the FAA as the basic requirement for a Technical Standard Order (TSO) for multipurpose electronic displays. While not required, ARP1874 and ARP4067 give recommended means, but not the only means, of compliance to this standard for CRT based displays. In addition, while not required, ARP4256 gives recommended means, but not the only means, of compliance to this standard for Part 25 LCD displays. That document is subject to change to keep pace with experience and technical advances. A similar document for Part 23 aircraft does not exist at this time, however these documents may be used as the basis for electronic displays intended to be installed in Part 23, 27, and 29 aircraft, realizing that additional requirements may also apply.
