Manual Calculation for TO Pitch Attitude Target
Was reading an old thread about a 747 accident and came across this interesting quote.....
"During rotation you normally aim for about 15 degr pitch attitude, and as soon as you get airborne follow the FD and shoot for V2 +10.
Initial pitch attitude out of a field elevation of ±5000' with this kind of weight (and derated) would be around 13 degr I would guess. With a full rated TO it would be higher, then the 16-17 degr you mention could be right. Perhaps they don't use derated TO's for safety reasons there, I don't know. I've never been there and wouldn't mind if it stayed that way. On the Classic we used to calculate the initial pitch attitude, but on the -400 you just go for 15 degr and then follow the FD."
I have ever heard of an aircraft where the initial pitch attitude was manually calculated. Has anyone else seen this on other aircraft?
