oh God, what's going on?
Low visibility was reported, but they have EGPWS on board.
Too much time has passed already. But let's hope for the better. At least for the survivors.
EGPWS is a wonderful tool for situational awareness, but it cannot help when the terrain elevation change exceeds aircraft climb capability.
In a situation where he was descending in a turn, it's conceivable he turned toward higher terrain. A second concern is that, depending how fast he was descending, he couldn't transition from a descent to a climb fast enough, losing several hundred more feet before beginning a climb.
My thoughts and prayers are with those onboard and their families.The "keep my tail out of trouble" disclaimer: Though I work in the airline industry, anything I post on here is my own speculation or opinion. Nothing I post is to be construed as "official" information from any air carrier or any other entity.

The large-scale search has been suspended until Thursday morning. Ground operation in the probable site of the crash will continue at night.Air crashes don't just happen... www.aircrash.ucoz.net

In many countries, ATC is responsible for TRAFFIC separation only, not TERRAIN separation, thus they can clear you down to whatever altitude you ask for assuming there is no traffic. They expect the pilot to maintain his own terrain clearance.

It seems unreal to me that a modern airliner can crash into the side of a mountain? Wouldn't I know that mountain was there if I had my phone on with gps on and google maps going?
Shouldn't there be something a little better than that technology for a passener plane?

1. It doesn't stop us getting into dangerous altitudes and...
2. Once there, it doesn't open the throttles and pull up out of danger.
You can have all the high tech gear in the world available but if the pilot doesn't respond appropriately or the aircraft no longer has the performance to get out of trouble then that's it.....you're toast !
This incident certainly looks like a CFIT situation. The crash site indicates powered flight into the near vertical wall of the mountain. It must have been one hell of an impact as reports say that the deceased have been reduced to small parts.
May those lost RIP.Last edited by brianw999; 2012-05-10, 08:42.If it 'ain't broken........ Don't try to mend it !

Originally posted by Aviation HeraldThe coordinator of the rescue operation said, that the aircraft appeared relatively intact from the air however has received substantial damage after leaving a trail away from the crater down the slope
Witnesses report dense fog at the time. The crash apparently happened about 1.5km from the point of last transmission, so only seconds later. CFIT would be the most obvious theory. Is is possible that this aircraft did not have GPS and EGWPS installed and/or functional at the time? Is this a case of you-get-what-you=pay-for? How does this happen to a 21st-century GPS-equipped jet piloted by a Capt with 10,000 hours? Once again, I'm miffed.
