Salute!

Well, Bill, in the ‘bus, you trim to get the stick back to neutral and relieve whatever pressure those springs exert. So you are trimming off the load.
in the Viper ( not sure about Raptor or Stubby) there was only an eighth of an inch of movement and the computers used actual stick force for the commands. Was not hard to trim for the gee you felt in your butt! Heh heh. For those lacking “feel” the HUD showed instantaneous gee down to the tenth. Our first impression back in 1979 was the thing was a cross between an Atari game and a 1950’s Link trainer. But make no mistake, we trimmed and we trimmed as folks have since the Red Baron days.

My contacts in the ‘bus and Viper community claim that switching back and forth is a piece of cake, with the ‘bus not needing much trim at all, but no problem with a stick not mechanically connected to the elevator

I still want someone to explain how Airbus gets certed without any “increase in force with increase in AoA”, huh? Is it because the Boeing still has a mechanical connection to the elevator?
