Keith, your continued arguement on this seems to show inexperience. Not putting you down, but alot of us know otherwise for Class B. Out of Denver departing, when you hit 10000 you the speed button and get to climb speed asap. If you do 250 until 12500, I guarantee ATC will ask you *** youre doing.
Sometimes things in the AIM or FAR are just there for interpretation as PIC. (very very few things, but they are there) for example, whens the last time you chimed in on Chicago appch in the middle of rush hour to advise him you are going to cross the arrival gate 5 minutes later than your flight plan shows, and you'd like to update your arrival time with him so that FAR can be satisfied?
Just sayin'.

The reality of the matter is that ATC generally really doesn't give a flying (EDITED) what you're doing, provided that it's not:

a) A GROSS violation of the regs, and more importantly,
b) cause loss of separation.

I've been "caught" going into ORD flying 330 at 8000'. Completely innocent oversight on our part when we were initially cleared to 13,000' then subsequently cleared below 10000 during the descent. Between that time, we were assigned a new runway and got distracted setting up for the change. ATC noticed us blazing along at 8K and queried. Of course we see our error and immediately go flight idle and pop the spoilers, responding with "uhhh, slowing". His reply? "No problemo... I just figured that United 737 four miles ahead of you might have a problem if you run up his rear end". End of issue.

Last month, I cruised across the top of ATL airspace at 335 assigned airspeed at 11000. (Gee- if we can't fly more than 250, how can ATC assign that airspeed in the bravo?)

Today I climbed out of a Class B airport indicating between 220 and 250 knots all the way to FL200 to outclimb some weather. ATC didn't care and didn't even bother to ask why we were so slow.

The fact is, if they want you to fly faster (or slower) to accommodate traffic, they'll let you know, either through what's printed on the SID or through instruction.

Holy smokes dude! Lets re-read what he posted:

"Sec. 91.117

Aircraft speed.

(a) Unless otherwise authorized by the Administrator, no person may operate an aircraft below 10,000 feet MSL at an indicated airspeed of more than 250 knots (288 m.p.h.).

(b) Unless otherwise authorized or required by ATC, no person may operate an aircraft at or below 2,500 feet above the surface within 4 nautical miles of the primary airport of a Class C or Class D airspace area at an indicated airspeed of more than 200 knots (230 mph). This paragraph (b) does not apply to any operations within a Class B airspace area. Such operations shall comply with paragraph (a) of this section."

In other words, no need to slow to 200 kts when within 4nm and 2,500' of a primary class B airport.

The 250 kt limit applies when below 10,000'. This limit is not applicable for operational necessity. For example, the clean maneuvering speed of a departing 747 at high gross weight will be above 250 kts



"Of course", don't try this if your aircraft transmits FOQA data, which includes indicated airspeed and hundreds of other data points

You want a reg to quite that says it's ok to do something? You do realize that regs are written fir what you can not do, not for what you can....

Nothing there, you can do it
