What is the maximum speed limit in Class C and D airspace below 2500 feet AGL?

The maximum speed limit in Class C and D airspace below 2500 feet AGL is indeed 200 KIAS (Knots Indicated Airspeed). This regulation is in place to enhance safety in areas where there is typically a higher density of aircraft operations, including at airports and during approach and departure phases.

Limiting the speed to 200 KIAS helps reduce the potential for wake turbulence and contributes to better traffic management within the controlled airspace, where pilots may be operating at lower altitudes and closer to other aircraft. Compliance with this speed restriction is crucial, particularly for pilots operating in controlled airspace, to ensure the safety of all aircraft and to facilitate smoother operations in busy airspaces.

In contrast, higher speed limits in other airspace classes, such as in the upper altitudes of Class E or outside of certain controlled environments, may allow for faster speeds, but in Class C and D airspace specifically below 2500 feet AGL, the 200 KIAS limit applies.
