AoA etc.

RE: CONF iture #514
I believe the numbers produced by HN39 for the AoA make more sense, I would be interested to know how he did estimate them ?
The numbers are based on the relation between Liftcoëfficient and AoA which I derived from FDR data on an unvoluntary pitch-down/pitch-up maneuver of an A330 in flight QF72 as reported by the australian ATSB. Unfortunately the report does not provide the weight of the airplane and the ambient temperature at the time of the upset, which are essential parameters for this derivation. I have mailed a request for these data to the ATSB but got no reply. The derivation is based on my best estimate for these two numbers and I would be most grateful to anybody having more accurate information.

regards,
HN39
