The SAE Aerospace Recommended Practice (ARP) contains methods used to measure the optical performance of airborne 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), however, the majority of the procedures can be applied to other 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. 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 document defines three classes of tests. Each class of test is applicable to the different phases of a products life (e.g., engineering development (Class 1), production/quality assurance (Class 2) and service/flight readiness (Class 3)). The test requirements for each of these phases differ and hence the test procedures for each test class may differ. Each procedure in this document is Class 1 unless otherwise stated
