Would have been. How long does "immediately" take in your experience? I appreciate your familiarity with ICAO standards and with air traffic control. That doesn't answer the question originally posed.
Search and Rescue action, mandated by ICAO, is usually devolved to military units since the states involved will not usually want to maintain specialised civil aircraft for this task. hence the military air forces in KL and vietnam would be in the loop immediately followed by those of other surrounding atccs.
Again, how long does "immediately" take in your experience?
It is likely that Lumpur Radar on 132.6 who was controlling 370 at the handover point, would have been looking at a feed from Khota Bharu radar whose cover stretches almost to the vietnamese coast.
Aye.
meanwhile HCM's radar cover reached at least to the handover point if their report of observing a turnback is correct, so I think 370 was not out of radar cover at any time.
OK. This explains HCM contacting Maylaysian POC when they didn't get a check in.
this would have considerably shortened any uncertainty time. look up incerfa/alerfa/detresfa... all will be revealed in the accident report and not before, at least to us onlookers and the media.
Am familiar with those terms, thanks.
