Flight 370

[StevenRB45]

No electric, no autopilot surely?

Passenger jets are aerodynamically stable, so give it a calm day steady throttles and it would happily continue for until something disturbed it or no fuel.

There was a case concerning the golfer payne Stewart in a private jet where the passengers and crew were dead 20 minutes or so after take of due to loss of cabin pressure and the plane few across the USA before crashing once the fuel ran out, although the autopilot was on in that case.

I have been advised that aliens have it cloaked somewhere

But again are the engines not computer controlled and without electric they would fail?

It's been a while since I took much interest in plane design but i'm under the impression on passenger jets all major flight systems must have built in redundancy, so that any single failure of a system cannot lead to the plane being downed.
For example the A320 back in the 80s had no fewer than 6 flight control computers operating on a majority vote system so effectively any command in put went past a committee and if one disagreed it got shut down. You then can have 3 seperate hydraulic systems all doing the same thing and anyone of which is sufficient to fly. If your hydraulic pumps or generators go then then have basically windmills they drop into the slip stream to generate enough to get by.
You would assume as well that any systems that lose control input are not designed to shut down immediately, considering lighting strikes happen 1000s of times a year and can cause big problems for your electrical system.

So are we saying under no circumstances is it possible for all electric to be switched off or go off and even if it did it would still fly?

Wouldn't go that far, my point was more that if one electrical system should fail the chances are there would be a back up.

But I'm talking complete electrical failure as in no electric for whatever reason, it's the only conclusion I've come to

 

[StevenRB45]

Well they do say anything that's not physically impossible is a certainty (eventually).

 

[Gavv8]

The story about the engine telemetry being received for four hours after the plane went missing isn't going away, personally I think information is being withheld...for whatever reason.

 

[Alsatian1]

I agree, I think its possible that the crew were some how "incapacitated" maybe due to loss of oxygen or something but the plane carried on flying. As we all know planes can fly on there own for a long time without the aid of a pilot - indeed I think this scenario actually happened a few years ago with the loss of all lives

I think this was in Athens with a helios airways flight from Cyprus? Remember seeing it on air crash investigation once. At the time caused a lot of mystery and jets were scrambled due to potentially being a terrorist attack. In the end I think it was lack of oxygen knocked out all the passenger's and crew, as the jet pilots could see people asleep in their seats. Plane eventually crashed in some hills outside Athens.

This latest plane incident is rather more mysterious though, I agree with the conspiritists and think there is something more to it.

 

[Caravadossi]

But I'm talking complete electrical failure ...

Total elec loss was sorted some 50+ years back.
The RAF lost a few Vulcan B1 due to total elec failure that led to re-thinking the B2 systems. Each main engine provides elec power, plus auxiliary units (e.g. the drop-down airstream gen. mentioned above, as does the Boeing 777), a (Rover built) gas turbine engine, batteries.

[Ulpian]

Even my old UNO never had Total electrical failure, so I don't believe mechanical error can be blamed. It was a nutter.

 

[IJK]

I think its been hijacked and its landed somewhere. Be it Chinese defectors or Somalia pirates. I don't suppose they'll ever find it.

Im leaning towards this too , just wondering what it will be used for ? act of terrorism ?

 

[Numptey]

It's full of Fiat Panda Spares and is being taken to the midlands as they are so rare

 

[dave]

News is saying it was diverted by some one on board.... didn't say that wasn't an alien though.

 

[Ulpian]

It's still speculation. The security agencies apparently know more, but as yet they aren't letting on.

This is quite a mystery, and along with the nightmare in the Ukraine it makes current affairs rather gripping. Unfortunately.

I'm actually watching the news for a change and better than the current affairs on Eastenders which I have to watch once a week with my 93 year old nan. Seems once a week is enough though as nothing seems to change from week to week, same ****e happens. Only the brain dead must watch these types of program's

 

[Ulpian]

Agreed.

 

[custard]

If thats the case then it would have been a landing like the hudson river, they'd have got out into life rafts and been seen by now.

If it crashed and they all died on impact there would be debris strewn about.

I still think there is a lot more to this than meets the eye.

Assuming those onboard were concious.
