Electronic Flight Instrument System (EFIS) Displays
This SAE Aerospace Standard (AS) specifies minimum performance standards for Electronic Flight Information System (EFIS) displays that are head-down and intended for use in the flight deck by the flight crew in all 14 CFR Part 23, 25, 27, and 29 aircraft. This document is expected to be used by multiple regulatory agencies as the basic requirement for a technical standard order for EFIS displays.
Historically, FAA Technical Standard Orders (TSOs) and associated industry Minimum Operational Performance Specifications (MOPS) were developed to address sensor and indicator requirements for single functions, such as airspeed, altitude, or fuel flow. In contrast, modern Electronic Flight Instrument System (EFIS) displays normally present indications for multiple functions, but do not normally include the sensor. Until now, a MOPS did not exist to address the operational/functional requirements for such an EFIS display.
Requirements for this type of EFIS typically consist of a few requirements for each function, drawn from many TSOs and associated MOPS. As a result, TSO applications for EFIS displays have multiple deviations to many TSOs and may include incomplete TSO authorizations. This document is intended to facilitate EFIS TSO authorizations by addressing only the EFIS display requirements for a broad set of aircraft functions.
This document provides criteria for EFIS displays that are intended for use in the flight deck by the flight crew in aircraft to include, but not limited to, Title 14 CFR Part 23, 25, 27, and 29.
