scope:

This SAE Aerospace Recommended Practice (ARP) contains methods used to measure the optical performance of airborne electronic flat panel display (FPD) systems. The methods described are specific to the direct view, liquid crystal matrix (x-y addressable) display technology used on aircraft flight decks. The focus of this document is on active matrix, liquid crystal displays (LCD). The majority of the procedures can be applied to other display technologies, however, it is cautioned that some techniques need to be tailored to different display technologies.

The document covers monochrome and color LCD operation in the transmissive mode within the visual spectrum (the wavelength range of 380 to 780 nm). These procedures are adaptable to reflective and transflective displays paying special attention to the source illumination geometry.

Photometric and colorimetric measurement procedures for airborne direct view CRT (cathode ray tube) displays are found in ARP1782. Optical measurement procedures for airborne head up displays (HUDs) can be found in ARP5287.

Generally, the procedures describe manual single point measurements. The individual procedures may be readily incorporated into automated testing equipment (ATE) or other automated environments. This also includes, but is not limited to Fourier scopes and video imaging devices.

This report is published by SAE to advance the state of technical and engineering sciences. The use of this Technical Report is entirely voluntary, and its applicability and suitability for any particular use, including any patent infringement arising therefrom, is the sole responsibility of the user.

Purpose

This document is intended as a guide toward standard measurement practices in support of ARP4256 and AS8034 but is not limited to its requirements.

The use of this document is not as a basis for legal regulation. The purpose of ARP4260 is to provide display measurement procedures and is referenced in:

ARP4256, Design Objectives for Liquid Crystal Displays for Part 25 (Transport) Aircraft,

AS8034, Minimum Performance Standard for Airborne Multipurpose Electronic Displays, FAA AC 25-11 A,

Electronic Flight Deck Displays, FAA TSO-C113, Airborne Multipurpose Electronic Displays,

FAA ANM-03-111-18, Policy Statement on the Installation of Transport Category Airplane Flightdeck Liquid Crystal Displays.

AC 25-11 and TSO-C113 call out AS8034. AS8034 and ARP4256 refer to ARP4260. ANM-03-111-18 calls out ARP4256.

Appendix B provides a cross reference between the ARP4256 and AS8034 requirements and ARP4260 test procedures. Sections 2 and 3 cover background for general procedures and equipment setups.

Section 4 provides the specific test procedures for the parameters.
