A few pages back, the Indonesian SAR briefing states the following time line:
5.36 Airbus A320 flight 8501 departs Juanda
6.12 contacts Jakarta, requests weather deviation to left of M635 Airway and
climb to FL380
6.16 still observed on radar
6.17 radar contact lost, only ADS-B signal remained.
6.18 all contact lost
Some posters wonder why no distress call was made. The priority of the pilot is to fly the aircraft and if time permits, to call a mayday. Clearly, time did not permit.
Even though it was daylight, the aircraft may have been IMC, the weather radar in the cockpit inadequate, so difficult to dodge what appears to be horrendous CB embedded enroute. How likely is it that if correct measures were taken by the Captain to fly safely through what is common weather in these latitudes, that the aircraft would have broken up?
