Actually you can accelerate to normal cruising speed AT ten thousand feet. The restriction is below, in other words, it excludes ten thousand. I've done a few short routes in jet and we'd climb to ten thousand, level off, then accelerate to a speed often just below the barber pole. I've exceeded 250 any number of times within maybe three thousand feet of the ground.
Happiness is not seeing another trite Ste. Maarten photo all week long.

Quoting Justplanecrazy (Reply 3): if there is a 250 knt speed restriction below 10,000 feet then why on the ITVV B737 Stansted-Lisbon video is the pilot flying at 275 IAS at 8,000 feet?
Simple, in a number of places in Europe, U.K. for sure and I've seen it in Gr. the controller will issue a "no speed restriction" clearance giving the crew the option of a high speed climb, or descent for that matter. Flying into CDG I've NEVER seen the option and in fact usually get slowed to 250 kts up around FL180! Departing CDG the SIDS state 250 below FL100 unless authorized by ATC. I departed there one night heavy and Vclean was 290kts and CDG dept. got a little irritated until I explained that was as slow as we could go then she just said "please tell me in the future". "OOOOOOKay"
Quoting CosmicCruiser (Reply 7): No just an MD-11 at high gross wgt. Vclean is normally 287-289kts at high to max gross wgt.
After a high weight takeoff on the MD-11 the pilot usually has to keep the slats extended until FL100, and only then accelerate to Vclean and retract the slats, unless ATC allows him to accelerate beyond 250kts at lower altitudes.

Perhaps you worded that a little wrong. We would advise dept. on the initial contact that we would be climbing at xxxkts (a very common situation in a heavy jet on a long leg and at most all int'l arpts it isn't a req'd call) and they already know or will accomodate you and then you clean up on schedule. Any prob will result in a small vector but keeping the slats out until fl100 would be the last thing I would want to do....CC
