3.1 This practice is written to preclude damage or injury to property and personnel in the event of an unplanned landing by an unmanned aircraft at an airfield not equipped or trained to handle that type of aircraft and to prevent unintentional damage to the aircraft once it lands. It is intended for use by unmanned aircraft equipment designers, procedures developers, and ground personnel.

1.1 This practice identifies and describes equipage and procedures for safely handling unmanned aircraft forced to recover at alternate or diversionary airfields where personnel trained in recovering that type of aircraft may not be present. It is intended to apply to fixed-wing unmanned aircraft conducting non-visual line-of-sight operations. It is intended to establish common locations, labeling, and functions of equipment necessary to safely power down the aircraft without damaging it and common procedures for untrained personnel to follow to contact the owner of the aircraft. It addresses mission planning procedures, automated functions, and manual functions/handling procedures in the preflight, in-flight, and post-flight phases, respectively.

1.2 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
