Rudder position data
No never knew that that was recorded.
I avoided the bus and none of the six types I flew had that capability.
But it posses another question in that is there rudder pedal feedback from what the rudder is doing?
This was the case on a couple of aircraft I flew but not on the VC10 which is the kite I declared a May day on. We were in the dark as to why the aircraft was in self destruct mode and it was only when I switched the autopilot off to see if I could control it as a last resort that I realised it was a run away damper.
My previous aircraft one could feel what was being commanded through the controls.
