Hello to all;Is the speed limit of 250kts below 10000 ft only apply when you are going to land or this is also at taking off, when you need to go as fast as you can to get as much altitude as fast as you can?Thank you.

The speed of 250kts is applied to all traffic operating below 10,000ft. Above 10,000 you can accelerate to whatever you need. Also at some airports, within their airspace, speeds may be mantained to 200kts.

and don't forget IN CONTROLLED AIRSPACE. in uncontrolled do whatever ya like

At London, Heathrow (EGLL) speed is controlled from departure from the stack (280 knots) and stepped down during the approach to 160 knots before clearance for finals. In quiet moments however, first thing in the morning and late at night (there are no overnight jet operations at Heathrow) the controller might say

Hello to all;I will kept my speed as per regulation. Thank you for your time.See ya later;Miguel

well also keep in mind that while flying under a shelf of Class B airspace its 200kts max per regulations.Kilstorm

Incidentally, to climb as fast as you can as quick as possible is probably not the best way. Check your aircraft`s POH for best rate of climb speed. 70Kts in a Tomahawk (with me in it) maxxes out at about 600 fpm on a cold dry day at sea level. 80Kts its not so good..CheersLungs

Not really to apply in FS, since it's an ATC restriction, for EMERGENCIES (and the controllers shuffling everything out of the path) these restrictions are usually disregarded.But this incompetent FS2K2 ATC does not even have emergencies... or some reaction to transponder 7700...Hope that will be better in some future version.Torsten

Hi,There are special circumstances in which the 250 below 10000 does not apply. Mostly due to aircraft performance, a gross weight 747 will be cleared to 280 knots and Concorde is cleared to 300 knots after takeoff.Cheers,JohnBoeing 727/737 Mechanic

Only on a BGI (Barbados) do you get an unrestricted climb on Concorde: -Reheats off at 500R, flight rating at 1000QFE and Max climb power up to VMO. London you have to follow a noise abatement procedure, adding increments of power as you climb. Also you slow to 250kts holding speed at Ockham when 7nm inbound, rather than at the SLP. JFK is quite complicated - always playing about with the throttles - but you won't usually get the clearance to accelerate to VMO below 5000ft. Inbound flights start to slow up to 250kts when within 12nm of land.Andy

Hi Andy,Thanks for the info. I was answering the original post in general terms in relation to departures and gross weight. 90% of the time Concorde will be cleared to VMO below 10000 ft but as you say will most likely be restricted below 5000 ft due to noise abatement and departure procedures.As for the 747, no Captain will accept a speed restriction below 280 knots for a gross weight bird below 10000 ft on departure.
