damping / clamping
(SLF speaking) I notice on the Cessna 172 the rudder is externally clamped to (I guess) prevent damage to rudder or mechanical linkages back to the pedals. Does this mean any more sophisticated type with hydraulics relies on this residual pressure (as described by Clandestino) to damp the movement? Do these systems retain sufficient pressure after sitting idle for an extended period?
thnks.
