This ARP describes methods for measuring the visual performance of direct view cathode ray tube displays used in aircraft flight decks and cockpits. Procedures may vary depending upon the type of display (for example, monochrome, color shadowmask, beam index, etc.), but all types are considered.

Purpose:

This ARP describes the methods to be used in measuring those performance characteristics important for color and luminance use in direct view airborne electronic display systems.

Field of Application:

This ARP defines three classes of tests. Each class of test is applicable to the different phases of a product's life: for example, engineering development (Class 1), production/quality assurance (Class 2), and field service or 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 ARP is Class 1 unless otherwise stated.
