200 Below Class B
#21
I would read the FAR. You are confusing minimum clean speed with minimum safe speed. It's not unsafe to extend slats or flaps. On climb out you can exceed 250 if clean is higher however that does not apply to below class bravo. The climb out portion is a specific FAA interpretation.
Fwiw, there's a note on the flight plan leaving MDW stating the Class B speed limit should not be complied with - overhead ORD airspace starts at 3,600. Odd that if this is an issue at all, TRACON can waive it with a handshake agreement.

There are many departures that require delaying cleanup to meet speed restrictions. Just came out of MEX where you have to do that. Many departures in a Europe require the same.

I'm not sure that's correct - I don't think the speed limit is restricted to 200KIAS or less if it requires you to stay configured - operational or safety necessity would negate that. In this case, operational, and I'd settle for clean speed.

My airline got in some trouble with the FAA because we would routinely exceed the 250 below 10.000 upon departure! Note in route documentation now that says unless specific approval is given to exceed 250, speed should be 250, even if this means climbing to 10.000 with flaps 1! Specific places that complained where Lax and ORD.

Even though the FARs specifically allow operation above 250KIAS when necessary, it is always worth mentioning that you will need a higher speed when calling for clearance, and also when checking in with departure control. (Say, "We need 285 minimum in the climb). Also, at someplace like Ohare, where the SID says 250 till advised, be sure to wait till cleared for normal speed before accelerating.

Mexico and Europe have different rules. 250 is routinely exceeded below FL 100 in Europe, just ask. And in Mexico, speed limits are different at different airports and are enforced sporadically just like customs regulations.
