It was a 1-11.
Matt, thanks for transcribing that paragraph, although it leaves me slightly confused as to what DP was trying to say. Perhaps if he had inserted the italic words in the text it would have been clearer:
"Although the tail experiences an increasing negative incidence due to downwash with increase in attitude this increase is always 'beaten' by the decreasing negative incidence due to the physical change in attitude."
I guess the original quote by vish (assuming that DP was confused on definitions) is D P's way to lead up to the need to limit 'incidence' (AoA) by means of stick pushers? On its own it made no sense, since 'incidence' (AoA) is a 'valuable parameter' in any stall, is it not?
