Salute!

Some interesting thots Gordon and Grounded.

Mods cut off the Tech Log, But I'll post here and save the draft if this thread continues to be political and managment stuff and no serious tech discussion.

There could be more aero characteristics than the AoA vs stick force gradient. Yeah, it's nice to have the same "feel" as other planes ( not just the 737, although many Airbus planes do not have any such "feel"). The beast must be very "slippery", huh? By that I mean little "speed" stability. Checking out in Cessnas, Chipmunks, Champs, etc. , we old farts and many newbies learned the effects of changes in AoA upon control forces, and that speed can make it harder or easier to move the controls.

Somewhere along the line Boeing added STS, and the system doesn't seem to be an aerodynamic feature, but a sfwe feature that also does not seem to be directly AoA dependent, just speed. So why not implement something like MCAS and let the basic plane aero design alone? Hmmm....

Gums ponders....
