AF447 Plane Accident

[GommeInc]

This is quite shocking, when I first heard it didn't sound too bad. The BBC or some expert mentioned that the plane had enough gliding time to probably come safely into the water - which made me wonder why a RyanAir flight pretty much dropped vertically when it's engines cut out, but that's another story. It would be interesting to know what happened, not in a sick way though

Thanks, I was reading everything after that date on wikipedia and couldn't find anything which was more .

Haha yeah, I did that a few nights ago too. I'm actually surprised it has been nearly a decade since a large loss of life really.

Thats sad and like why did they not sent out a mayday or whatever its called or is there nothing on planes that helps people locate hem

RIP to those people!

Crews usually declare an emergency by repeating mayday three times (well that is the standard procedure but some crews just state mayday once because they have the emergency to concentrate on - most notably the US Airways flight which ditched successfully into the River Hudson). However, how do we know the crew had time to declare an emergency? Maybe they were caught off guard? Maybe the plane disintegrated leaving them no chance to declare an emergency? Perhaps the flight was hijacked and thus the crew were unable to communicate with ATC in fear of being murdered?

Who knows? The fact is, we don't know yet and we probably won't know for a long time.

Gliding time is based on a number of factors too and a gliding ratio is usually available in the SOPs.

First of, don't assume on what has happened to the flight. No one knows for sure what the hell happened. They do know a number of faults occurred about 14 minutes after last contact with ATC. This is because Air France and most other airlines will have a system that sends a message to the Maintenance base that a fault has a occurred so they know what needs fixing/replacing or whatever.

Why the hell can't I assume. Everyone is. :rolleyes:

If it's a double engine failure a plane can glide for about 30 minutes, if I'm right, so surely the pilot would have had time. Don't know why the thought of lightning because planes are designed to be hit by lighting. Could have just had a complete and utter systems failure and gone straight down into the Atlantic.

I also forgot to mention the following. Yes planes are designed to fly in storms with ease and planes can be hit by lighting strikes all the time and it doesn't end up going off radar or crashing. Although, this seems to of been a very bad storm of some kind which could mean the lightning may of been a lot more stronger or just unusual or whatever at the time. Which caused the flight AF 447 to have problems on board. Fires on aircraft is a no no, so if a fire has happened, then there's one of the big clues. Although, once they found the black boxes. That's when the real answers come out.

Why the hell can't I assume. Everyone is.

I wasn't aiming it at you, I'm just saying it . Sorry about that.

how are divers meant to find black boxes in the middle of the atlantic anyway?

[Sammeth.]

They have locator beacons :8

Black boxes are designed to send out a signal, homing beacon if you want to call it that once they hit water. It does this for so many days, I forgot the number. It is a very hard job, since the size of that ocean is HUGE. They will have to get specialised equipment in to try and help them. They may even have to call in a mini-submarine to go and get them. All depends, I hope to god they are able to find them and get them without any problems.

i was watching something and it said they give of a signal fr 30days or somthing.

correct me if i am wrong

Yeah that number rings a bell in my head. Its about 30 days.

Yeah, I don't know really. There's been a hell of a lot of speculation and not many answers. I'm hopeful the investigators will find the answers soon enough, just a matter of time and money really.

I think some sources have said that the ocean depth can reach 14000ft, so if that's how far the FDR and CVR have sunk to, then it will be a difficult recovery. The South African Airways 747 which went down a couple of decades ago over in the Indian Ocean was within waters as deep as 16000ft.
