Salute!
Well, mister 42 and Fizz and others. Thanks for the reminder for those just checking in and those who do noit yet understand the intent and implementation of the MCAS - software and electrical wiring.
How many times must we here and Boeing and FAA and others have to point out [ the purpose of] the MCAS software kludge with its control over a very powerful aerodynamic feature, and then bypassing the older trim stab electrical switches, and then not telling the pilots and then..... GASP!!!
The damned feature was implemented to increase back stick control force at high AoA. PERIOD!! Sure, I don't want the stick getting lighter when I increase AoA close to the stall. But the cert requirement states that the pressure must increase as we get to the stall AoA. Apparently, Boeing couldn't do it aerodynamically without lottsa testing and mods and ...... So we got this half- ice kludge doofer and nobody knew about it.
Gums sends...
