Title:Aircraft Nosewheel Steering/Centering Systems
Issuing Committee:A-5b Gears, Struts And Couplings Committee
Scope: The intent of this AIR is twofold: 1) to present a descriptive summary of aircraft nosewheel steering and centering systems and 2) to provide a discussion of problems encountered and 'lessons learned' by various airplane manufacturers and users. This document covers both military aircraft (land-based and ship-based) and commercial aircraft. It is intended that the document be continually updated as new aircraft and/or new 'lessons learned' become available.
