In Class Bravo airspace, what is the speed limit below 10,000 feet?

In Class Bravo airspace, the speed limit below 10,000 feet is 250 knots indicated airspeed (KIAS). This regulation is in place to ensure safe and organized traffic flow in areas with high-density operations and near airports where many aircraft are taking off and landing. The restriction helps manage interactions between faster aircraft and slower ones, particularly those on approach and departure paths.

Maintaining this speed limit promotes safety by reducing the likelihood of wake turbulence encounters and gives Air Traffic Control greater ability to manage aircraft spacing and sequencing. The choice of 250 KIAS is particularly significant as it balances efficiency for the aircraft while ensuring safety near busy terminal areas.
