- A thermal airport refers to an airport that is specifically designed to handle thermal traffic, such as gliders and other light aircraft that use natural air currents and thermals to stay airborne. These airports usually have runways that accommodate the takeoff and landing of these types of aircraft and offer facilities and services that cater to the needs of thermal pilots. Additionally, thermal airports are often located in areas with good thermal conditions, such as hilly regions or areas with consistent weather patterns that support thermal activity.
