I didn't say there are not instances when speeds cannot be waived by ATC. The post that I responded to said that speed limits are written in stone and ATC cannot waive them. That implies never, when in fact there are many instances in which they CAN.

Which FAR airspeeds can be waved by ATC?

250 kts below 10000 in Class B is the one easy one I can think of. I believe the same applies to Class C and D limits if in a radar environment, but not sure about those.

250 below 10k cannot be waived by a controller, no matter what airspace you're in.

I didn't think so....I don't think ATC can waive any of the FAR Airspace speeds.....

Agreed. Only "the Administrator" can waive FAR speed restrictions, and the controller is not "the Administrator." When IAH (or was it DFW? Can't remember) did the high speed climb below 10k program a few years ago, the FAA had to issue a special waiver. It's not something that the controller is able to do on his own.

....it was IAH.....not that it matters in the ATR....:laugh:

Any of them, at the crew's request, for performance reasons. Minimum clean at MGTOW was somewhere north of 280kt, in a former life.

I would hesitate to call a few heavies and military aircraft "many instances."
