MG I was just genuinely interested to know what part of PoF the MfB does not know?
That's ok, just waiting to see if it was serious question. I was QHIing at Middle Wallop when the BERP blades were introduced on the Lynx. I noticed that if you trimmed the aircraft for a, say, 5 degree turn to the right, if you let go of the cyclic, the bank angle would continue to increase. If you did it to the left, it stayed where it was.
On a list to Boscombe, I asked the TP about it and that was his answer.
