Re: Malaysia Airlines Flight 370

@Mav, no commercial airliner is allowed to fly in the US without a full airworthy certificate and this is only granted after extensive trials.

Boeing's first fly-by-wire airliner, it has computer-mediated controls; it is also the first entirely computer-designed commercial aircraft.

As it was one of the first fly-by-wire aircraft this would have made the testing more rigorous.
I think I read somewhere that it had to go even more testing because being a 2 engined aircraft it had to satisfy the FAA it was capable of flying the Atlantic on one engine if needed.

Re: Malaysia Airlines Flight 370

If it was the battery would they not have had time to send out a distress signal ?
Very tragic situation, hard to imagine how friends and relatives of those people who were on the aircraft must feel.

Re: Malaysia Airlines Flight 370

It could be a catastrophic engine failure, explosion or terrorist attack.
Since a passenger's passport has been stolen it leans more towards a terrorist attack.

Re: Malaysia Airlines Flight 370

if it was explosive there would be a wide debris field, far more likely someone tapped into the avionics and forced the plane into a nose dive straight down whilst cutting off all comms options through the on-board computer.
flybywire should never be used for passenger carrying planes because of its vulnerabilities to such actions, its always going ot be a problem when you introduce a single point of failure into a system that its weakness will be exploited by those bent of mayhem and destruction, time will tell exactly what it was that caused the problem (assuming they care enough to find and reconstruct everything)

Re: Malaysia Airlines Flight 370

Worth reading the pilots analysis on the whole scenario - while not always accurate, it can make some interesting reading as many of them fly these types of planes.

Re: Malaysia Airlines Flight 370

with a water depth of less than 100m its shocking that the fuselage hasn't been discovered, a slick of up to 15 miles length has been "reported" yet no actual sightings after more than 24h hours in the drink, something very hinky in the whole thing, I wonder if this is going to end up the same as a certain American airlines flight that was blown out of the sky by the US navy.....

Re: Malaysia Airlines Flight 370

This is unlikely to be a major system failure. All systems on board are duplicated and some triplicated.
It is beginning to look very much like a terrorist attack.

Re: Malaysia Airlines Flight 370

This was reported some hours ago.
Quote
Way too early to speculate but the majority of the passengers were Chinese about 160 of the 230 passengers. The Chinese have been experiencing relentless terrorist attacks from the Uyghur people from Xinjiang in the far Western China. The most recent attack was a bloody machete wielding mob who hacked up 30 plus people in Kunming, China a whole separate region in Southern, China. There have also occurred almost monthly police confrontations and terrorist attacks in Xinjiang. An attempted terrorist hijacking was also carried out last year in Xinjiang on an E-175
but the crew did a valiant job in getting the aircraft on the ground expeditiously and the passengers and crew fought off the attackers. Many of these terrorist attacks go unpublished and are unknown mostly outside of China.

There was also an attack at Beijing Railway Station last week when 29 people died. Also all airports in China have been on full security alert for a while. This is definitely looking like terrorism.

I would have thought that a pilot could  over ride any computerised system and take control of the aircraft .

Re: Malaysia Airlines Flight 370

My stepson flys 777 out of Heathrow.
There are always loads of speculation when an a/c is lost.  
I feel for all the relatives involved and hope they find out what happened soon.

It's been over 24 hours, if it were a terrorist attack surely somebody would have admitted to it it by now.

not when the entire aircraft is controlled through the computer, so long as someone gains access to a maint port inside the passenger cabin (there are 5 of them in a 777) and is hard linked to the IEEE system they can theoretically control the entire aircraft from a portable computer....
all the avionics are linked to the computer, the power supply buss's can be deactivated through the computer (and a clever attacker would disable comms before taking control of the system to prevent the manual bypass from being possible) its the only way that the aircraft would of ceased spitting out all comms (including SPI) especially when you consider that tracking stuff is done automatically from the tail end antenna.
but as has been pointed out if it were an actual attack (unless its a proof of concept attack) then you would expect whichever loony group to have ben making press conferences about it (Al Jazeera carried confirmation from Taliban high command less than 5 minutes after the first plane hit the twin towers) that there is nothing would indicate an avionic malfunction is more likely the cause (possibly just a cct breaker tripped and cascade failure from that point on) disabling comms and flight control, certainly if there was a 15km twin oil slick (500m apart) that would indicate the plane had sunk as a whole and in far deeper water than the reported max depth of 100m (which could be why there having such trouble locating the wreck) time will tell although in all cases of aviation mishap's faster is always better

Re: Malaysia Airlines Flight 370

UPDATE- it's been reported that the plane attempted to turn back after it lost contact but is still unverified
A post from Malaysia Airlines on Facebook has said that a passenger on another flight has spotted debris of MH370 but it's still unknown.

Re: Malaysia Airlines Flight 370

One report has also increased the number of passengers flying on stolen passports to 4.  Why were they allowed to board in the first place?
