What is the standard transition speed limit below 10,000 feet MSL?

The standard limit is 250 knots indicated airspeed below 10,000 feet MSL. This rule keeps operations safe and orderly in busy airspace around airports by giving pilots a predictable speed that helps ATC manage spacing and reduces wake turbulence exposure for slower inbound traffic. Since this is an indicated airspeed limit, you don’t adjust it with altitude in the way you might with Mach numbers—your airspeed indicator shows whether you’re at or below 250 knots. Exceptions exist for safety or when ATC provides a different clearance, but unless instructed otherwise, staying at or under 250 knots is the correct practice.
