Mention of a type might be useful, but I will assume you mean Boeing types. Have you thought what the tailplane is doing when you rotate? There are compressibility effects as you sweep the tail near to the ground, and also you are blanking the tailplane behind the flapped wing. An extra pull is needed. Not something I would think DC9/BAC1-11/Tridents suffered from. Mentioning that amazing CAT3b aeroplane, why doesn't someone tell us how marvellous it was?
