ICAO Annex 12
Ian W
Recommend you look at my post No. 8089 that was written way back on March 25, 2014. There is not much wrong or lacking with the ICAO procedures (i.e. Annex 12) for locating missing aircraft - they just need to be followed in a timely manner. My post described the various steps and actions to be taken once an aircraft appears to be missing. This was clearly not done by several involved parties - in particular, the various Malaysian authorities. The Annex certainly does not intend for S & R organizations to wait for the aircraft to reach its endurance before initiating a search. Those in commercial aviation with responsibilities associated with S & R need to gen up on Annex 12 and keep a copy handy at their work stations.
