Preliminary Findings Suggest Pilot Error in Air France Crash
The pilots of an Air France jet that crashed into the Atlantic Ocean two years ago apparently became distracted with faulty airspeed indicators and failed to properly deal with other vital systems, including adjusting engine thrust, according to people familiar with preliminary findings from the plane's recorders. The final moments inside the cockpit of the twin-engine Airbus A330, these people said, indicates the pilots seemingly were confused by alarms they received from various automated… (online.wsj.com) Más...Sort type: [Top] [Newest]

I agree with you in regards on blaming the pilots, so quickly.. Though like I've said before on another blog here in this site[you where there], I can understand that there was a good probability the Pilots did error at some point, but at the end I STILL STAND FIRM, that it was more than likley SECONDARY, to all hell that was breaking out in the cockpit, and I am kind of getting the paranoid sense of the great posibility that BEA, AF, AirBus, even though the later 2 did not say anything this time is trying to smooth the pilot thing, so they can PLANT the blame on the Pilots and, leave to one side the A/C, [scapegoating]???> thats my impression
In regards to Sonar>>>>>I dont't know never really thought about it and ant the same time could sonar, I have a couple of questions, 1. Does sonar have the range, and 2. i know Sonar is affected by water densities, and it cannot penetrate sometimes, would this be the same being in the air??, Dunno, you bring an interesting point though

Robert why not use GPS as a secondary source for airspeed, at least in bracketing within a certain safety range as I know it could be a second or so behind the actual speed but would have certainly helped the pilots focus on control. Here I go projecting what I believe the events that led to this crash after this info: 1 Capt. out of cockpit. 2 multipliable pitot tube malfunction.3 disconnect of auto throttles 4 pilots preoccupation with all the various alarms and warning lights.5 plane inters an unnoticed stall-recover scenario. 6. airplane either enters into an unrecoverable dive or a flat spin. Two factors that will be addressed will be Capt stays in cockpit when in serious weather and training for pilots to be retained to.....FLY THE PLANE FIRST
GPS is useless for airspeed indication because the air itself is moving sometimes over a hundred knots, and that's without even considering wind shear. Wind shear confounds things by adding some chaos to the wind speed, and consequently the air speed.
By the way, when i mentioned sonar, I didn't necessarily mean a typical sonar mechanism. Perhaps I should have said a sonic system, since sonar implies something more specific. I hadn't considered moisture content of the air. I'll have to think about that. While it would make a difference, I'm not sure by how much. If there is enough moisture that it's rain, radar would pick it up. If ice, well, then you have other problems.

Victor you are right it only gives ground speed. I stand corrected, but and there is always a but, if it was monitored by the pilots it could have been used for bracketing thus kept them out of a stall. If the readings were say 490 kts over the ground then at least you would have some reference info when the pitot's failed instead of none. I also think that had the capt. been in the cockpit and the auto throttles had disengaged he would have known from experience the approx. locations to set the throttles at for continues safe flight something only experience and skill gives you
A couple of big questions, could the pilots fly the plane when the automatic systems are in the way? How much manual control is possible in these fly-by-wire aircraft? Could the pilots override the auto thrust systems when the sensors are partially disabled?
As far as blaming the pilots goes, aren't we a bit premature for that, especially if, elsewhere in the article, it states they didn't get training for this circumstance?
