you clearly can't read

this is a quote from an ealier post of mine on this thread

"I find if you pay the nice chaps at CAA some money, they give you a bit of paper saying you can go faster than 250kts below FL100, but only when in receipt of a radar service. Piece of paper has 12 months validity before they want more money."

:ugh::ugh::ugh::ugh::ugh::ugh::ugh::ugh:

Yes you are missing something! The problem for many on here is they actually do not k
 

:eek:That's easy, just use your real name and stop hiding behind non de plumes!

I certainly k for one
and I reckon that most of us k deep down

how dare you suggest I don't?

Pushing 250 Kts is not uncommon. My mate flies for a living and when repositioning VFR they are doing just below 250 VFR below CAS (could be below 3000' for example).

Last time I was in the states I got a call from ATC...."Traffic 9 o'clock a KC10 at 5500 VFR"......;)

For those of mode S transponders - in UK, speed outside regulated airspace is now being watched.... :suspect:

How do they work out the IAS? The speed limit is IAS, not GS and not even TAS.

Not impossible but you would need to feed the winds aloft in real time into the software. Where would the wind data come from, accurate enough to prosecute? From airliner air data computers, but they fly thousands of feet (at least) above GA traffic. GA traffic with Mode S will not in 99% of cases be radiating any Enhanced parameters.

So I think this is a windup. The only traffic that could possibly be monitored would be CAT flying in Class G.

IO540, There is no working out to be done. IAS is one of the enhanced parameters that Mode S will transmit to the ATC radar position.

Yes, Enhanced Mode S only. Over 5700kg or over 250kt TAS certified max cruise.

Exactly - the speed limit is 250 kts.
