Is there a speed limit in class b airspace? (some class b is above 10,000msl.)
Well if other aircraft at your altitude (and going same direction) are all doing 280 kt GS and you are doing 330 kt GS... guess what? You are doing 300 KIAS and (especially in ATL) you are getting a "Speeding Ticket"... It isn't hard for them to figure out....chperplt said:

I agree... they will NEVER tell you that you are cleared to go over 250 KIAS below 10,000ft (they can't, that speed limit is a reg and they can't waive that) BUT THEY are the ones who monitor that reg, if they choose to look the other way, that is their choice...chperplt said:I understand that...
I was flying through NY and on with BOS center.. Someone asked the controller if a "maintain max forward speed" was a clearance to do more than 250 below 10K, and the controller said officially 'NO", but there isn't any way he's going to know what you're really doing, or even care enough to say anything. Obviously not all controllers think alike..
AWACoff...the FARs have no mention of speed limits (outside of 91.117 which says nothing about Class B having a speed limit).
They will know by averaging your speed against the general flow of traffic. So will your FDR, especially after you run into someone. Speed regs exist for several good reasons one of which is collision avoidance among various categories of aircraft down low.
Thanks... My comment was a little bit of a joke. I know they can figure out quite easily how fast your flying.
That's because ATC will sometimes allow heavies to accelerate to greater than 250 knots below 10,000. LAX routinely allows westbound departures (heading across the Pacific) to exceed 250 in the climb. They tend to climb better at higher airspeeds.SFO area at the weekend - ATC were making a point of telling departing heavies (jets) from SFO and OAK to keep speed below 250.
I'm not sure where you're getting this information. I've flown for 121 airlines based in ORD and ATL and I can tell you that neither are very anal about speed.Falcon Capt said:Atlanta has been to only TRACON that has been real anal about the speed limit, Chicago has queried a couple pilots on occasion... but haven't been near as anal, usually it is a "Nxxxx say speed" and the reply is "250 kts" as you are yanking the thrust levers back to idle.
