Scope
This report has been compiled by the Landing Gear Systems Terminology Panel of SAE Committee A-5 (Aerospace Landing Gear Systems). It represents an effort to gather together those terms commonly used within the discipline. Some terms are of course common to other disciplines as well. Others, however, are unique in form and/or meaning to the landing gear discipline. The need has been noted to set these terms down and provide a standard definition in order that communication within the discipline may be conducted with a common understanding. Full use has been made of available published information, and a list of references is provided. See also References (a) to (e).
Terms listed are usually applicable to a general functional area of landing gear disciplines. These general functional areas include; landing impact, directional ground control, velocity control (acceleration, retardation, and arrestment), structural support, ground flotation, and ground maintenance. In the listing of terms and definitions, each term is followed by a code in parenthesis which indicates which basic functional area or major component to which the term is most applicable.
Codes indicating basic functional area or major component are as follows:
-
a

Rationale
AIR1489 Revision C was created to add pertinent terminology related to electrically actuated braking systems. The new terminology reflects the definitions established in the applicable specifications including AIR5937 and AS5663. Several other minor typographical modifications were also added to Revision C.

Issuing Committee
A-5 Aerospace Landing Gear Systems Committee
The A-5 Committee addresses all facets of aerospace landing gears: design, maintenance and in-service experience. It publishes Aerospace Information Reports (AIR), Aerospace Recommended Practices (ARP) and Aerospace Standards (AS) for use throughout the industry. These documents provide current design information, recommended design practices and design standards for landing gear systems. A-5 also provides a forum for presentations on current technology and technical interchanges needed by each engineer to stay abreast of a fast moving field.
A-5 is comprised of three subcommittees: Wheels & Brakes (A-5A), Landing Gear, Struts and Couplings (A-5B) and Tires (A-5C). A-5 is an assemblage of top landing gear engineers from throughout the industry and the world including customers and commercial users. The committees form and modify the various specifications and standards for both military and commercial applications. Benefits from committee participation are knowledge, customer responses and first-hand input into tomorrow's specifications.Reference

* Redlines comparisons are available for those standards listed in the Revision History that contain a radio button. A redline comparison of the current version against a revision is accomplished by selecting the radio button next to the standard and then selecting 'compare'. At this time, Redline versions only exist for some AMS standards. SAE will continue to add redline versioning with ongoing updates to SAE MOBILUS.
