If the runway length they used was too short then it wouldn\x92t have got that high before descending again.

that\x92s not a Boeing procedure. The RTO case is more limiting so if you can take off you can retract the gear straight away.

Main panel. And the handle is a rubber wheel. The flap lever is shaped like a flap. But that hasn\x92t stopped it happening multiple times in the past. The yellow and red lines on the speed tape will start to converge and should be an indication to PF. On all Boeing / Airbus that\x92s it\x92s happened on the pilots have recovered by re selcting flaps. Selecting F1 will save you. It\x92s a Boeing procedure written in the manual.

It\x92s obviously producing plenty of thrust as it rotates from the dust. It would take longer than that for the aircraft to lose lift if the flaps were retracted instead of the gear. It take a while for them to run.

Aerodynamically it would fit with taking off without flaps - normal rotation and climb until clear of ground effect at around 200ft at which point the lift would drop a lot. It\x92s not a single engine failure as no sign of yaw.

Nonsense. Please don\x92t post things as fact that are just speculation.

Boeing and the AAIB only arrived at the scene this morning. Black boxes were recovered on Friday.

This is a rare good piece of journalism. A good summary of how the accident investigation will proceed. Anyone thinking it will be solved in the next few days should probably read this first. The what went wrong is usually established before the how. Subjects: None |

Sorry if this has been covered in the previous 1 million posts, but do we know if the training captain or trainee was handling the takeoff? The one thing that does change at V1 is PF\x92s hand comes off the thrust levers and joins the other hand on the control column. How long until people then put their hand back on the thrust levers varies a lot. Especially if turbulent or there is a perception of difficult handling ie) engine failure which often delays it. If your hand is on the thrust lever then should be able to feel them moving - unless gripping them so firmly it over rides the clutches.
Oh, and the FDRs haven\x92t been read yet as they were damaged in the fire. Subjects (links are to this post in the relevant subject page so that this post can be seen in context): Engine Failure (All) V1 |

For what it's worth, if the fuel control switches were rapidly cycled as per the dual engine failure memory actions, the engines should both have restarted and recovered full thrust within a matter of seconds. This is part of the certification and Rolls Royce publish the procedure (unofficially) as a last-ditch attempt to recover an engine that's experiencing a locked-in surge condition.

No, not easily. Need to be done separately. Unless done from the jump seat with 2 hands.

Boeing will try to blame the operator, and the operator / country will try and blame Boeing. It goes back to USA litigation culture. Whoever is seen to be at fault is on the hook for a multi million or billion dollar lawsuit. Plus national pride, corporate reputations.

One thing that I remember from when I was a simulator TRI/TRE on a Boeing was that as an instructor you get very used to operating critical
switches rapidly without following any procedure, in order to set the sim up for a single engine landing etc. When I was then line flying next I had to guard against doing the same thing in the real aircraft.

Theory alert : If you don\x92t have, or delete the cruise altitude in the FMC the aircraft will command a level off at 400ft, with the thrust levers reducing thrust significantly (I\x92ve seen it in the sim and happened at least once for real to my operator). It\x92s easy to do when loading the descent winds if you hit the wrong button. Could this have been confused with a loss of thrust?
And I would say the cut off switches do make a fairly unique click when being moved - I can hear it in my head as I write this! Subjects (links are to this post in the relevant subject page so that this post can be seen in context): Fuel (All) Fuel Cutoff Switches |
