Is that true please? I was taught that the speed restriction applies in ALL airspace below 10000ft amsl except when authorised by ATC for the sector they control in CAS.
Thanks
The speed restriction applies to aircraft that are not subject to full ATC separation.
So Class A and B – no speed restriction; Class C – no speed restriction for IFR.

Please check SERA.6001(a) and/or appendix 4 to SERA. As I wrote, there can be ATC imposed speed restrictions and such speed restrictions can be disregarded after ATC authorisation.
Thanks
(Really, all pilots should be familiar with SERA!)

Exactly!
Well that’s told me! I had better memorise SERA before my next flight.
I don’t even know where to find SERA :)
With all respect, you’re opinion isn’t relevant. A VFR flight has to follow “ATC instruction” — that is, a clearance — but can demand a different clearance if the one offered is impossible or unsafe to follow. In the worst case if ATC can’t offer an alternate clearace, the pilot can exercise emergency authority.
Haven’t really given all this much thought, but when reading that ICAO chapter it’s rather straight forward IMO. But I have seen in the AIP that IFR must have equipment to be able to follow ATC instructions, no such thing for VFR. Besides VFR in class C enroute is cleared to fly from A to B at a prescribed alt, and that’s it.

What exactly does that mean…?
LeSving, from Annex 2.
3.6.5.1 An aircraft operated as a controlled flight shall maintain continuous air-ground voice communication watch on the appropriate communication channel of, and establish two-way communication as necessary with, the appropriate air traffic control unit, except as may be prescribed by the appropriate ATS authority in respect of aircraft forming part of aerodrome traffic at a controlled aerodrome.
A VFR flight within CONTROLLED airspace is a CONTROLLED flight.
4.8 VFR flights shall comply with the provisions of 3.6: a) when operated within Classes B, C and D airspace;

Except class E, of course…
