Viper is Fly by Wire and its stick senses force to control surfaces (rudder too if computer decides).

Now, what about rudder pedals, when you apply rudder pedals are they hooked to computer (FBW) or hydraulically linked to rudder.

Rudder, nose wheel steering and brakes are all controlled electrically by computers. Electrical signals from transducers connected to the pedals are translated by the computers which sends signals to the different systems. There are no mechanical linkages at all from the rudder pedals.

Salute!

Rudder pedals move about a half an inch - linear transducers.

Unless FLCS laws have changed, they input direct rudder position, not yaw angle or yaw rate.

This was really neat for troops like me with short legs, or for the gals. Older planes had rudder pedals that moved 6 or 8 inches or a foot! So I had to squirm in the seat to get enuf rudder for a severe crosswing landing.

The Viper rudder pedals could be moved in and out so much that a 6'6" basketball player and a short squirt like me could have them just where we needed.

Gums...

And they are adjustable too...just pull out the handle next to the eyeball vent and move them fore and aft.

A kid came thru Klamath Falls once that stood about 6'8"-ish. He had to put the pedals to the mechanical stop to keep his knees from hitting the tops of the tunnels. Laughing

The pedals also shared what seemed like a common pivot point but may have been some other mechanical setup. When you stepped on 'em the foot you pushed with moved slightly inboard, vice other pedals that moved linearly fore and aft like Gums mentioned.
