2、ATEMENT A: Approved for public release; distribution is unlimited. Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-HDBK-87213A (USAF) FORWARD This handbook is approved for use by the Department of the Air Force and is available for use by all Dep
3、artments and Agencies of the Department of Defense. This revision updates MIL-HDBK-87213 to incorporate new information related to flat panel matrix displays and incorporates references to VESA FPDM 2.0, along with other refinements. The original MIL-HDBK-87213 replaced an Air Force Guide Specificat
4、ion (AFGS) on displays and another on aircraft instruments. The first section (Controls and Displays Segment Requirements) of this handbook is closely related to the controls and displays requirements in the Joint Services Specification Guide on Avionics Systems. The rest of this document covers req
5、uirements applicable to the basic elements of an aircraft control and display (and instrument) subsystem. Appendix A contains historical reference material taken from the AFGS on aircraft instruments, which dealt mainly with electromechanical instruments. Although many of the issues covered there ar
6、e now the subject of symbology standards (see MIL-STD-1787), the history of how it was done on mechanical instruments (which many current pilots learned to fly with) can be very valuable. This document no longer contains the specification sections of the old guide specifications. It does include mos
7、t of the material from the old guide specification handbooks, including most of the sample specification paragraphs. This material has been updated to include new technical information and lessons learned, and to eliminate references to military specifications and standards that controlled design of
8、 equipment rather than dealing only with performance requirements. Comments, suggestions, or questions on this document should be addressed to ASC/ENOI, 2530 Loop Road West, Wright-Patterson AFB OH 45433-7101 or emailed to Engineering.Standardswpafb.af.mil.

This handbook provides sample specification paragraphs, ratio
38、nale, guidance, and lessons learned that are useful in the development of the primary flight displays and mission avionics controls and displays subsystem for an aircraft. This includes Head-Up Displays (HUDs), Helmet-Mounted Displays (HMDs), and Multi-Function Displays (MFDs), used for presentation
39、 of graphics as well as display of television (TV), forward looking infrared (FLIR), and radar video, and the associated electronic display generation equipment. Rationale paragraphs explain the reason for specifying each parameter. Guidance paragraphs explain what values are normally used and why.
40、Lessons learned paragraphs serve as a historical information repository for this technical area. 1.2 Use. This handbook cannot be used as a contractual document. Sample specification paragraphs within this document should be completed using the information in the guidance and lessons learned paragra
41、phs, and may be used in a contract-peculiar item development specification, subsystem specification, or system specification. 1.3 Structure. This document is arranged to cover topics as they are normally covered in display equipment specifications. The tiered numbering scheme commonly found in gover
42、nment documents is used with one major exception, each topic is covered as a package. The rationale, guidance, and lessons learned paragraphs follow the sample specification paragraph, and the corresponding section 4 (Verification) paragraph follows immediately after the section 3 (Requirement) pack

In the event that deviation from the guidance herein results in improvement of system performance, reduced life cycle cost, or reduced development cost, or where the requirements of this specification result in com
44、promise in operational capability, the user is encouraged to deviate, with careful 1 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-HDBK-87213A (USAF) consideration of all system tradeoffs. Such deviations should be brought to the attention of t
