Runway Extension Results In Mud Slide At CRW

To say the runway is not affected is being optimistic. At the edge of the overrun area the soil bank is more or less vertical. This bank is on the verge of collapse. A safe distance away from the edge, would roughly be a line starting from the bottom of the bank and rising at 30 degrees to the horiz...

RE: Air Asia QZ8501 SUB To SIN Crash - Part 14

I don't think the fact that the co-pilot had less experience has anything to do with it. Both pilots were passed as fit to fly the aircraft, therefore even with very few hours any pilot should be able to handle any control situation. The bit about both ELAC's being switched off: according to the sch...

If Aluminium has a density of say 4 times water.
then underwater the weight is only 3, due to the buoyancy effect of water.
But unfortunately , when you lift the thing out, the missing extra ton/m3 comes back to break your rope.

RE: Air Asia QZ8501 SUB To SIN Crash - Part 13

Pihero,: thanks for all the useful input. Just a question? As a pilot, you have to maintain altitude in your airway but to what accuracy.? what I am getting at, can you reduce the forces on the aircraft by riding up and downdrafts or do you absolutely have to stick to your required altitude. Obvious...

Quoting Pihero: reply 63: The increase in energy you stated is correct if taken relative to ground level.(which is not moving) The increase in energy will be the updraft acting on the airplane as an external force. but if you take as your reference frame the moving updraft air mass with the aircraft...

RE: Air Asia QZ8501 SUB To SIN Crash - Part 13

My take on the different debris positions. Looking at the photos of debris brought up so far. the airplane hit the water slightly nose up and a bit left wing down in a pancake landing. Looking at forces at work here: the most mass is in the middle 2/3 of the fuselage. That means that the projecting ...

RE: Air Asia QZ8501 SUB To SIN Crash - Part 12

Looking at the blue illustration of the track: It would be interesting to know what happened between points 2 and 3. From what I could read up, the data on the recorder is sampled a few times per second. The constantly reducing speed , whether the plane was going up or down, seems to indicate loss o...

RE: Air Asia QZ8501 SUB To SIN Crash - Part 11

Thanks all for the interesting replies on what makes data recorders work. there seems to be 2 opinions here, break up when hitting sea, or in flight break up. the first has now been more or less confirmed. I would add the possibility of control surface damage when encountering bad weather , followed...

RE: Air Asia QZ8501 SUB To SIN Crash - Part 11

First post here.
I have a question: do the data recorders stop working when power is lost or do they have on board batteries to keep them going?
the reason I ask is because if the aircraft lost power at some altitude, will the recorders keep going down to sea level?
