This Aerospace Information Report relates considerations for design test procedures and test data evaluation for qualification of tire spray deflection devices.
This Aerospace Recommended Practice (ARP) provides recommended methods for measuring performance of skid control systems. It includes test items and equipment.
This document covers recommendations for the application of existing qualified and approved in-service fixed wing aircraft tires, wheels and brakes to military and commercial rotorcraft. NOTE: This document does not address the use of radial tires due to insufficient data to support their approved use on rotorcraft, see paragraph 4.3.14 for specific impact on ground resonance.
The static mechanical stiffness properties of aircraft tires are fundamental to any computation of wheel and landing gear shimmy characteristics, and are important guides in anti-skid system and aircraft wheel design. While the mechanical stiffness properties of aircraft tires are frequency sensitive, the static or low frequency values are important because they are the ones most easily obtained by laboratory testing and are most commonly found in literature. The following recommended methods for measurement of such properties are believed to represent practices which will give reliable and repeatable measurements, either at one facility or among different facilities, using equipment which is commonly available in most tire testing installations.
This SAE Aerospace Information Report (AIR) provides an overview of the tire properties, strut properties, damper properties, and other landing gear mechanical properties that contribute to shimmy stability and are required for shimmy analysis. A variety of analysis techniques and assumptions are presented.
This SAE Aerospace Recommended Practice (ARP) is intended to document the process of landing gear system development. This document includes landing gear system development plans for commercial/military, fixed wing, and rotary wing air vehicles.
This SAE Aerospace Information Report (AIR) discusses past and present approaches for monitoring the landing gear structure and shock absorber (servicing), opportunities for corrosion detection, methods for transient overload detection, techniques for measuring the forces seen by the landing gear structure, and methods for determining the fatigue state of the landing gear structure. Landing gear tire condition and tire pressure monitoring are detailed in ARP6225, AIR4830, and ARP6137, respectively. Aircraft Brake Temperature Monitoring Systems (BTMS) are detailed in AS1145.
The purpose of this Aerospace Information Report is to provide the industry with methodologies for measuring tire/wheel gear alignment and the range of acceptable alignment settings for various types of non-military landing gear. This AIR will focus on the general aviation, corporate, and regional aircraft landing gear but could have applicability to commercial aircraft.
This SAE Aerospace Information Report (AIR) will review new landing gear (engine off) taxi system technologies currently being developed by various companies and describe the basic design concepts and potential benefits and issues. This AIR will identify the associated systems that could be affected by this new technology. The document will review basic design and operational requirements, failure modes and identify system certification requirements that may need to be addressed. The technology is evolving as this paper is being written and the data present is currently up to date as of 2015.
This document discusses the work done by the U.S. Army Corps of Engineers and the Waterways Experiment Station (WES) in support of SAE A-5 Committee activity on Aerospace Landing Gear Systems. It is an example of how seemingly unrelated disciplines can be combined effectively for the eventual benefit of the overall aircraft system, where that system includes the total airfield environment in which the aircraft must operate. In summary, this AIR documents the history of aircraft flotation analysis as it involves WES and the SAE.

This SAE Aerospace Information Report (AIR) provides information on landing gear operation in cold temperature environments. It covers all operational aspects during ground handling, takeoff, and landing. It includes effects on tires, brakes, shock struts, seals, and actuators.
The purpose of this document is to provide a listing for current commercial and military aircraft landing gear systems and their types and manufacturers. Data has been provided for the following commercial aircraft types; wide body jet airliners, narrow body jet airliners, and turboprop/commuter aircraft and the following military aircraft types; fighter, bomber, cargo, attack, surveillance, tanker and helicopter categories. The aircraft that have been included in this document are in operational service either with airlines, business, cargo or military operators. No information is presented for aircraft that are currently being developed or that are not in extensive usage. This document will provide an informational reference for landing gear engineers to access when evaluating other gear and aircraft systems. Future revisions of this document will add aircraft as they enter into service.
