What altitude range does the control zone cover?

A control zone is an airspace surrounding an airport where ATC provides a protective service for aircraft during the critical start- and end-phases of flight. It starts at the surface and extends upward to a defined upper limit, which in this scenario is 2500 ft. That means the entire zone from the ground up to 2500 ft is within ATC control, ensuring that arriving and departing flights can be safely sequenced and separated. Why this range fits best: it directly aligns with the purpose of the control zone—covering the low-altitude airspace where most takeoffs, patterns, and initial climbs occur, so ATC can manage traffic movements right at the airport. The other options either start above the surface or extend too high, which would either exclude low-altitude air traffic from the controlled zone or unnecessarily encroach into higher-altitude airspace that ATC isn’t intended to manage within the immediate airport area. So, the altitude range covered by the control zone is from the surface up to 2500 ft.
