It's clear....

Thank you, desitter.

I have seen some members here with an almost childlike faith in the sfwe and control logic.

From an old, grizzled pilot that flew the very first fully FBW system in a design that was statically unstable below 0.91 M, and had to deal with the computer logic and such, I am becoming deeply concerned.

- loss of basic airmanship
- confusing warning display chirps, flashing lights, changes in the basic displays, reversion to "laws" after "laws".

We old dinosaurs were very concerned about the raw nuggets that came to us. They were the Atari generation, and adapted to the computers easily. We were concerned that they would lose their basic pilot skills because the jet was so easy to fly at the edge of the envelope. So we kept harping upon basic aero principles and showing how the jet WOULD NOT PROTECT YOU ALL THE TIME!!! Gasp! Beam me up!

I do not see this with our current crop of heavy pilots, and it scares the hell outta me.

Trust me, a completely FBW system is not a simple electric connection to the control surfaces. Even the Airbus reversion modes are using yaw, pitch and roll inoputs to limit the control surfaces. And they should in most cases.

What I don't see is a simple reversion sequence and the use of "standby gains" for aero data that is determined BY THE COMPUTERS to be unreliable.
