If ATC asks for "best forward speed" in Class Bravo airspace, can you exceed 250 KIAS?

The correct answer emphasizes that regulations must be adhered to, regardless of ATC instructions. In Class Bravo airspace, there is a specific regulatory speed limit of 250 KIAS below 10,000 feet. While Air Traffic Control (ATC) can request "best forward speed," they cannot authorize an aircraft to exceed this legally mandated speed limit.

Following regulations ensures safety and compliance with the laws governing airspace operations. Thus, even if an ATC request seems like it may imply otherwise, pilots must prioritize adherence to the established speed limitations when operating within Class Bravo airspace.

The other options are situational and do not align with regulatory requirements, as they suggest conditions under which violating regulations could be acceptable, which is not permitted.
