Bloody hell. I have dreams sometimes where I see a plane falling out of the sky like that and I wake up all stressed thinking it's ok it doesn't happen like that in real life

I have that dream too from time to time. Needless to say, not one of my favourites.

It's weird, I'm never on it, I can just see it happen and it makes me feel proper sick

In the absence if the news thread, as someone on here appears frightened of debate, plane down in Brazil. 

 

Video seems to show an odd crash. Flat direct vertical spin. Rudder failure?

I have no idea. On your first point, have you read Mark's post on the matter?

[StanSP]

Oh my word. That's horrific

It’s absolutely sickening watching something like that… it’s hard to imagine a more terrifying last minute of someone’s life…

Nope, didn't know there was a whole new forum. Which, obvs, I now know. 

 

My comment you replied to I popped in the aircraft porn (great thread for mini avgeeks like me) ....hence the technical question about possible rudder failure

Of course - I was just trying to inform you without causing an argument.

Looks like an aerodynamic stall which could have been for a number of reasons.

You can glide out of a stall though, right? 

 

Must be a loss of control / loss of systems to be unable to pull out of that

Depends on the stall and the situation, though Line-X will know more specific details than I about that.

Some are irrecoverable. You can't spiral without a stall, but you could be right. it may have been induced by a problem in the cockpit or the control surfaces, or possibly a build up of ice.

I've read about the ice. Probs a very silly question, but planes at 30000ft+ fly routinely at -50c .....including over the arctic, Alaska, Siberia etc. how on earth could ice prove so problematic?

Much more of an issue for propellor driven aircraft than jets that fly at those altitudes, IIRC. Icing has sadly been the end of a lot of aircraft.

Glad I found this out AFTER regularly flying on Flybe!

For ice to form there needs to be moisture. I can’t remember the exact parameters, but if there’s visible moisture (clouds) and the OAT (outside air temp is below 15c) then anti-ice systems should be armed. The OAT of 15c is on the ground though, so it’s if you’re taking off in those conditions. Similar rules would be applied when descending through moisture at low temperatures.

 

Somewhere like Brazil, they’d have to contend with ice from storms. If there’s cumulonimbus towering over 30,000ft with dense precipitation on radar, then they’re climbing over them or giving it a wide berth. Any plane would get battered by this kind of weather so they tend to avoid them at all costs.

One the day of the crash there was intense icing around 17000, the altitude the aircraft was flying. The ATR 42/72 has had major problems in the past with wing icing and to try and resolve this problem ATR extended the icing boots so they extended much further along the leading edge of the wings..
