Control law reversion, etc

@ Phoenix.......

Good video links.

The point about "direct" is that the computers still bias your control stick deflection or pressure using some math function.

Is one degree of stick deflection equal one degree of elevator deflection? If not, what is the ratio?

Is ten pounds of stick force about like we used to feel with the fully hydraulic systems ( no mechanical linkages, just hydraulic pressure to move an actuator) that used pneumatic and spring doofers to provide a bit of feel. And BTW, are the stick movements at the same pressure regardless of how many degrees they move?

I have no problem with the test pilots using some DIRECT implentation initially, then going to the NORMAL mode. But I have no idea of the gains or control input ratios to control surface movement or even how fast they move ( rate of surface movement).

Hooray for Bombardier. I like their approach.

But I still wannna see some charts and graphs.
