#MS804 ACARS update & comments

+MS804 #EGYPTAIR MS804 - ACARS update & comment:



ACARS report (reproduced at the end of this article) received from Aviation Herald http://avherald.com/h?article=4987fb09&opt=0 :

which reports are automatically transmitted by the aircraft via satellite shows various alerts prior to aircraft transponder going off. Most serious is Smoke in the Avionics bay and Smoke in Lavatory near cockpit which could have come from the Avionics bay.
This could explain why the Aircraft did not respond to Greek ATC and did not transmit any emergency message prior to its rapid descent. A fire in the avionics bay could have destroyed the avionics and affected the flight computers. ...

The cause of the fire is not known. It could have come from a device placed there by a member of the technical staff who could have accessed the bay at one of the airports the aircraft called at.
The fire could have been caused by some other technical fault with the wiring or equipment in the Avionics bay.
This info excludes a traditional explosive bomb, although does not rule out terrorism altogether. It probably also excludes the pilots or on board crew. The avionics bay on the A320 can only be accessed from outside the aircraft using a hatch when its on the ground.
It does not rule out the possiblity of pilot error in reaction to the fire. E.g. the fire would have caused alarms in the cocpit to go off and would have affected the flight computers flying the aircraft on autopilot.
Assuming the fire was not too serious, the pilots would need to have switched off the autopilot & to have attempted to ascertain whether they were able to still fly manually. At night, and at high alitutude, one has to ensure that the aircraft does not stall. In AF447 the pilots failed in this respect. I explain all of this in my free eBook

#MS 804 Egyptair flight. Initial views

#MS804 INITIAL COMMENTS - S G WALTHER

 

+Egyptair  Flight 804 High Altitude "crash".

13 04 CAT  UPDATE Greek authorities report plane made sudden swerves, dropped by 22000 feet and & spun before disappearance

Potential Causes:

1 Terrorist Act. (e.g.. bomb)
2 Catastrophic Technical failure (e.g. with rudder or other control surface
3 Fire
4 Unlawful act from pilot or someone else as is most likely the case with MH370 and was the case with the Germanwings crash.
5 Pilot Error usually in concert with simultaneous less serious technical problem e.g.. allowing the aircraft to stall (AF 447)

...

In AF 447 an iced-up pitot tube which measures air speed failed and caused the on board computer to send warning messages. The pilots allowed themselves to become overwhelmed by these warning messages, failed to fly a perfectly flyable plane properly, and allowed it to stall. Another example of such a high altitude stall caused by pilot error is recent Air Asia crash.

STRANGE THAT NO WRECKAGE HAS BEEN FOUND

Egypt Air crash. Strange that no wreckage has been found in three or so hours since first light despite being in Med - an area with heavy traffic incl fishing vessels, commercial vessels, passenger vessels etc.
In fact its so busy, that its odd no-one seems to have seen or heard anything at the time.

It is of course remotely possible that there is no wreckage because  a "Hudson" type landing occurred and that the plane went down intact. But one has to remember that the Hudson was a river, which is usually quite flat.

At sea, even if the pilot was able to attempt to do the same, history has shown that some part of the aircraft, often an engine, touches the sea before the other and the aircraft then violently cartwheels around that part and breaks up. E.g.  Ethiopian Air Crash near the Seychelles.

EERIE SIMILARITY TO MH 370??
Also: the aircraft apparently disappeared after signing off from Greek Air Traffic Control. There is no indication as yet that the aircraft completed the handover to Egyptian ATC before it disappeared. Have a look at my window of opportunity theory regarding MH370. Link below.

UPDATE 12:54 CAT  It seems now that aircraft failed to respond to Greek ATC shortly before it was supposed to be handed off to Egyptian ATC. It disappeared from radar shortly after entering Egyptian airspace.

QUESTION: WHY AFTER AF 447 & MH370 are we still unable to find missing airliners quickly???? When will we learn??
