From post #658 (abc/Reuters news story)
Groups representing relatives of those on board say that's a good thing
Voice 370 called on the new government to review all matters related to MH370.
"We urge the new government to include as part of its agenda in the next 100 days … a further investigation and inquiry into any act or omission across the entire spectrum of operations that may have impaired tracking, search, rescue and recovery," a statement released by the group said.
Ganesan Nethi, a lawyer who had represented the families of victims from MH370, said the approach the new Malaysian Government was taking was a "heartening and refreshing change".
Really hope that the above request from the Voice 370 Group on further investigation and inquiry into acts or omissions that may have impaired tracking, search, rescue and recovery is actioned by authorities because there are aspects of the Malaysian investigation which seem incomplete. For instance there is the ATC transcript from K.L Centre including both the air/ground communications and the co-ordination communications, but there is no such transcript of the Vietnamese ATC air/ground Comms or co-ordination.
There seemed to be some kind of confusion between the K.L side and the Vietnam side on whose job it was to raise the alert.In the context of “possible search areas” this is of enormous consequence. In the ordinary course of ATC operations communications checks with an aircraft are commenced 3 minutes after a scheduled missed call and a SAR phase is declared immediately the safety of an aircraft is in doubt according to 3 levels of apprehension with distress phase being the highest.
The K.L transcript shows communications checks did not commence until 20 odd minutes after the missed scheduled call, and the Distress Phase wasn’t declared until some 5+ hours after the missed call. Search and rescue action cannot be commenced until a distress phase is declared.
When a flight is not in normal communications and is also lost on radar then unless there is solid evidence to the contrary in 99% of cases the comm checks and sar phase are declared very quickly. So a 5hr gap in SAR phase declaration when talking about jet ground speeds of 1000km/hr impacts on the likely success of search and rescue action.
Always struck me as rather odd that apart from a few newspaper stories quoting some of the transcript back at the time (supervisors asleep etc) of it’s release, nothing more was ever made of the SAR Alerting function ATC is responsible for.
