Product Code:SAE ARP5569
Title:Landing Gear Retraction / Extension Systems
Issuing Committee:A-5 Aerospace Landing Gear Systems Committee
Scope: This Aerospace Recommended Practice (ARP) will cover normal and emergency landing gear retraction/extension systems. This includes all equipment necessary for the control and sensing of the components used for raising and lowering the gear, up-locking and down-locking the gear, opening and closing the associated landing gear doors, and any latching of this equipment. The document will provide recommended practices for the use of conventional technologies and for those newer technologies now coming into use. It will include the regulatory and other safety requirements for these systems together with recommendations for; sequencing and timing, sensor selection, and failure monitoring of both normal and emergency operation and the support of maintenance and test needs.
