BA 747 crew commended for escaping near-stall on take-off
South Africa's Civil Aviation Authority has praised the airmanship of British Airways Boeing 747-400 pilots who battled to prevent a low-altitude stall after the leading-edge slats unexpectedly retracted during lift-off from Johannesburg. (www.flightglobal.com) Más...Sort type: [Top] [Newest]
Well, unlike Airbus panel, where there is actually notion of the flap's current position and the position that crews choose, there is only one plane in the Boeing that has that kind of gauge: B777 and only plane with external camera, used for taxing. If I am remembering correctly, B747's slats are supposed to retract when the reverse is engaged. Cabin Crews said that the engine gauge showed two of the engines, engaged in reverse, which it means the computer did the right thing, pulling up its slats. One I am concerned is that why reverser was engaged when the plane took off....
I think the only thing we should concern ourselves with is not weather the pilots had cockpit or visual evidence of what was happening to the slats, but that the imminent stall of the massive aircraft on its take off-roll was handled safely and correctly..Its for the CAA and the Aircraft manufacturers to debate the wisdom of Fly by Wire.
I was a mechanic on 747-400's in the early 90's and I thought there were flap/slat position indicators displayed on a CRT with a pictoral display of the aircraft. Maybe it was on a maintenance page of the EICAS.

Why is this so? Better yet, why can't a $250 million aircraft provide video of external flight control and undercarriage componenets?
