Did anyone see the documentary on Discovery channel which featured an Air France Airbus jumbo jet crash epidemic? I'll cite the narrow parameters the
pilots of these craft were facing as their instruments malfunctioned, as portrayed in this television feature.
The pilots were shown in animated form, inside the cockpit. One guy handled the controls while a thousand beeping buzzers sounded. The co-pilot was
busy thumbing through a manual. The pilots had NO WAY of guessing or knowing airplane speed, since the pitons were iced up with super cooled moisture
(ice). The host repeatedly mentioned that the plane MUST be kept within a 10-15 knot envelope or else the plane would stall, period.
Apparently the pilots couldn't deduce anything from engine rpm, or thrust levels. The show made it look futile for the pilots to do anything but pray.
Statistics seem to agree as a whole bunch of these crashes happened.
I kept thinking about that envelope. Too slow? Stall, lose altitude. Too fast? Lose altitude. There was no mistaking this wording. This jet must stay
between 450-460 knots or it will begin to stall. The actual knot figure may have been 300, or even 500 knots, in which the airbus is supposed to be
stable~it doesn't matter. What matters is that without experience, great experience, most pilots are not going to be able to perform exceptional above
specs speed maneuvers.
The pilots in the Airbus documentary were forced to fly blind, while being misinformed by all instruments in the system. Since they had no visual
reference (storm over water at night) and no way to guess how fast they were going, they went down. Did the pilots even know how to calculate airspeed
by looking at thrust or engine output? I should think they would have been able to do so, and fly. Maybe it's not taught at flight school. Too bad the
terrorists that made combat quality turns at record speeds while hitting bullseye's seemed to have thoroughly mastered all aspects of veteran level
Now, if this is true for other jets, this envelope that must be adhered to, doesn't that just add to the difficulty the alleged terrorists crack
pilots must have endured?
So, as to the TV documentary~~~all these jumbo jet airbus models crashed, and eventually a computer model gathered enough data to point at the
airspeed pitons being iced up, a poor design that allowed supercooling. I think it's odd that a system would be so ill-designed as to mislead every
system. If I watch the show once more, I will listen for the narrative that mentions the narrow airspeed envelope.
