Max speed Class B above 10,000 ?

[Pistonpilot]

What is the max speed in Class B airspace if the Class B extends above 10,000?

 

[regionalcap]

no speed limit

Going for an interview, huh?

Above 10K - no limit

Below 10K - 250 max

Within class B - 250 max

Within class B and extends beyond 10K - no limit

under the shelf of B - 200 max

Thanks guys

no speed limit

Sure there is...you can't break the sound barrier above the cont. US

Just stop right there.

Within class B - 250 max

That's not correct. Class B has no published speed limit. The only speed limit specific to Class B is the 200 knots under the floor within the lateral limits you mentioned.

Within class B and extends beyond 10K - no limit

Er... sorta. The 10K is the dividing line; Class B has nothing to do with it.

200 knots or clean maneuver speed under the class B. There is no need to leave the flaps out or configure early to slow to 200. Clean maneuver speed is perfectly acceptable and legal. In some airplanes that can be higher than 250 even.

 

[Amish RakeFight]

Sorry for the cookie-cutter answer.

Technically, one can operate faster than 250 within class B in the clean configuration (no flaps or LED's) if there is an operational need.

But I don't think it's entirely correct to say that there is NO speed limit inside of B. There is; but it may be higher based upon specific aircraft that require a higher speed.

speed limit specific to airspace IN Class B? Never heard of one - however the 250 under 10k rule still applies. Class B above 10k has no limit because you are above ten ( in other words, i agree with CA1900 - Ok, thanks bye.)

 

[CA1900]

But I don't think it's entirely correct to say that there is NO speed limit inside of B. There is...

No, there isn't. Re-read 91.117 if you don't believe me; it's as clear as can be. If you slow down to 250 (or whatever you min clean speed is) at 11,000 going through the ATL Class B, I will rear-end you.

§ 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.


(c) No person may operate an aircraft in the airspace underlying a Class B airspace area designated for an airport or in a VFR corridor designated through such a Class B airspace area, at an indicated airspeed of more than 200 knots (230 mph).


(d) If the minimum safe airspeed for any particular operation is greater than the maximum speed prescribed in this section, the aircraft may be operated at that minimum speed.

Our minimum speed during the climb is ten knots above flaps-up speed, which is above 250 whenever loaded. Normal climb is 100 knots above V2. As a courtesy, we notify ATC we'll be conducting a high speed climb, though ATC already knows.

Thanks for the clarification guys. Same difference, as they say. :beer:
