Location of an Aircraft in Distress Repository (LADR)

  • ​What is LADR?  * Click HERE to access the LADR 

The Location of an Aircraft in Distress Repository (LADR) enables operators to meet the requirements of Annex 6 — Operation of Aircraft, Part I — International Commercial Air Transport — Aeroplanes, Chapter 6, 6.18.3 to make position information of a flight in distress available to appropriate organizations, as established by the State of the Operator, while also meeting the expectation from the search and rescue (SAR) community that such information will be held in a single place such that information from different autonomous distress tracking (ADT) systems would be collected together, thereby facilitating quick access to the last known position of the aircraft. 


There will be three main categories of LADR stakeholders. An individual entity may fit into one or more of the above stakeholders (e.g. an airline may be a LADR contributor and also a LADR data user).
  • LADR administrator;
  • LADR contributors (data providers to LADR) inclusive of the developmental submitter, (4.1.2 refers); 
  • LADR data users (data consumers to LADR).
