Straight after take off it would climb at around 160 knots at around 18 degrees pitch, not sure what rate this gives but its probably around 2 - 3000 feet per minute initially.After noise abatement (3000agl)accelerate to 250 or 300-ish depending.Generally climbing at around 2000fpm once clean, a bit more when light.
Not familiar with Manchester recently but it used to be a Conga departure I think, via Honiley to pick up a LHR STAR.BA boys can get specific here,I don't know.
Descent is normally also between 2 and 3000fpm at around 280kts but wind up the speed and use speedbrake easily gives 6000fpm-ish initially.
Cheers
