Control/trim law bias for AoA or speed

Thanks Turbine for the 777 poop.

Seems Boeing likes a plane that trims for speed/AoA versus one gee corrected for attitude/climb angle. And the pilot has to command a different trim speed/AoA if I read the data correctly. No automatic THS to maintain commanded gee.

Interesting that pulling/pushing the stick ( stick/yoke, what the hell) against the trim setting has increased force. So there is an artificial force feedback, huh?

I was also impressed with a fairly simple reversion sequence when the primary laws go away.

The stall protection implementation also seems very intuitive to pilots that did not grow up learning to "monitor" the Airbus system do its thing. Hmmmmm.....

Again, thanks Turbine.
