    The 250 knot speed limit is below 10,000’ msl. Now it’s true that most Class B sits within this restriction, but the Bravo is not what’s generating the limit. It’s a minor distinction, but here’s a practical example from just last night: landing SLC to the north on the QUENN 5 arrival, and I was descended by ATC to 10,000’. The ceiling of the Bravo is 12,000’, and I was already well within the lateral boundary. We were running late and I really had to pee. How fast do you suppose I was going? ;)

    The only situation where I've heard of them is on SIDs which specified a maximum speed above 10,000' until advised.

    Yeah I can see it happening in that situation. For the most part though, below 10 grand controllers just don’t care about the 250 kts. Like a cop who picks and chooses who they pull over for speeding.

    On the other hand, pilots also need to be prepared to put on the brakes below 10 grand if needed for sep. Example, one time I had a Falcon 10 doing 360 kts at 6,000 ft and eating up a DH-8 in front of him. I simply told him that I needed him at 250 kts below 10,000 ft. Came back with a snotty “It’s 250 indicated...not a ground speed.” I knew damn well that he didn’t have (roughly) a 100 kt tail wind. I calmly came back with, “roger Falcon 345, turn left heading xxx for the sequence.” He canceled right after that. :D

    I know. I was just giving a (possibly) over-pedantic explanation of why I agreed with your conclusion.

    I heard a Southwest guy asking if he could slow down the other day. I almost asked if he'd come over from American or something :p
