.........and if I may enter the fray, I am constantly concerned by the alacrity with which folks will go for 'wet figures' when the first of the drizzle arrives - appearing to ignore the definition of 'wet' - thinking that it is all that straightforward and perhaps not realising what a big ask it is - especially if you are r/w or obstacle limited.
Maybe I'm just old fashioned having been brought up on twin turboprops whose performance OEI was 'interesting' to say the least!
OS, I don't get the point you are making about the OEI acceleration being 'less than 10% of normal'; I understand precisely where you are going in that Para, but not that specific figure. Please could you elaborate for me? Many thanks.
Cheers
