NTSB and Rudders
Reply to WINO post 600.
OK, I say again. Wind shear, from turbulence, across the
openings of the Pitot-Static System can cause low pressures which can induce erroneous flight instrument readings. Turbulence can also induce aircraft attitude transitions, (ask Captain Goode about his aircraft's attitude gyrations.) These triggers can induce instinctive pilot flight control inputs that may result in aircraft upset accidents! e.g., NWA 705, EgyptAir 990, SilkAir MI185, etc.,etc. (Reference to EgyptAir 990 accident)
I know the world has changed but the laws of physics have not. The B707 or the 767 still accelerate at the rate of G! Instantaneously! The Captain called for engine shut down after the aircraft was indicating .99 Mach! Incidently, the elevators did not split until after the .99 Mach point! (EgyptAir 990 accident)
This is the first time, in almost 100 years of flight, that we are aware of, that an aircraft has entered the core of a vortex behind a fully loaded B747 at climb power. (AA 587)
A little knowledge can be dangerous, but too much reliance on book learning can lead to obfuscation! Remember the basics!
