Speed below 10,000ft
Hi All,
Just a quick question please.
When under 10,000ft is it a requirement that an aircrafts speed must be 250kts or under , but my main question can you go over 250kts under this Flight level

Yes you may if you are in Class A, B airspace i.e controlled airspace if in anything else then 250kts max below 10000ft, unless you are military then its no supersonics over land.
It has been a while since i looked at Airlaw issues, please correct me if i am wrong.
Also there is no class B in the UK.

as a day to day rule 250kts maximum bellow FL100/10,000’ unless you have radar control, in which case you can go as fast as you like as long as you get permission from your friendly air traffic controller

The 250kts speed limit does not apply to the following:
Flights in Class A and B airspace
IFR flights in Class C airspace (No Class C in UK)
Flights in Class C and D airspace when authorised by an ATC unit
Test flights in accordance with specified conditions
Aircraft taking part in flying displays when authorised by the CAA
Aircraft subject to written permission granted by the CAA
Aircraft not subject to the ANO
*Note for all you guys and girls flying in to EGPF and EGPH, when you are transferred by Scottish to approach, you will (90% of the time) transit through Class E airspace where we as controllers cannot lift the speed restriction, we may well say there is no ATC speed restriction, however this DOES NOT override the 250 below 100 it just means that we don't have a specific speed for you to fly at

The generic rule for Class A is as stated by caniplaywithmadness. However, where a procedure has a speed limit specified (250Kt SLP on inbound STAR for example) then this is mandatory unless lifted by the ATC unit.
Both this and the previous post are only applicable in the UK of course and may be different in other States.

Mutt,
Operators of such aircraft may be granted permission to exceed the speed limit for airworthiness reasons on application to the CAA.
However, procedure design speed limits would still apply unless lifted by ATC. One way of getting the limit lifted would be for the pilot to tell ATC of his limitations. Otherwise we are not to know there is a problem.

Also as an addition, you are not allowed to exceed 200knts for the approach when within 10NM radius of the airport you are landing at, and under 3000 feet. (The 123 rule: 10nm, 200knts, 3000ft). This is in Canada.. does this apply eleswhere?)
