Failures in Feedback Systems
Hi,
I learned from CJ, on the Concorde YD was slightly disturbed when HF radio was transmitting. Yaw Damper is a good example of a "closed loop" feedback System.
EMI/EMC aspects caused this problems later solved, i guess through shielding, etc.
PF was inside the loop after A/P and A/THR dropped.
As i understand, his "inputs" came from the displays ahead of him and from other "inputs" like noise, G, etc.
His actions with SS were clearly inadequate specially near the "corner". For example, roll.
Question:
His initial "pitch up", the ones that put the A/C in the zoom climb could be justified by a set of erratic "inputs" he saw?
The change of speed to alt could be a "based" decision (acting thinking to be under imminent risk) and putting the plane above REC MAX?
