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 flightcrew 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 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 section 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 original AS8034 document specified minimum performance standards for Electronic Displays which, at the time of publication, included only Cathode Ray Tube (CRT) displays. The AS8034A revision updated the minimum performance standards to include specific performance standards for Liquid Crystal Displays (LCD) not covered in the originally published document. The current revision, AS8034B, contains clarification on the scope of applicable types of electronic displays, updated references as well as specific updates to the general minimum performance standards for electronic displays identified in Section 3, specific performance standards for LCDs in Section 4.5, and some clarification to CRT specific minimum performance standards in Section 4.4. This document was developed by the SAE A-4 Electronic Display committee and supersedes AS8034 and AS8034A.
