Sorry Cpdude, I don't think I read your reply properly before my last post (too early in the morning). I'm suprised that an "overpowered" A/C like a B744 can't get to 3000' without having to accelerate to VREF+50 first. Didn't realise about the flap5 thing. What's your normal T/O flap setting?
I'm sure the SID requirement to climb asap to 3000' is not a noise issue but is a traffic conflict one. Hope you miss all those lighties in summer!!
