Where does the floor of controlled airspace begin over Half Moon Bay Airport?

The floor of controlled airspace over Half Moon Bay Airport begins at 700 feet above ground level (AGL). This altitude is significant as it marks the transition point between the controlled airspace, which is subject to specific regulations and requirements for flight operations, and the surrounding uncontrolled airspace where pilots have more flexibility but also bear greater responsibility for collision avoidance.

In many areas, controlled airspace is designed to provide a level of safety for both commercial and general aviation operations. Over Half Moon Bay, the establishment of 700 feet AGL serves to maintain safe vertical separation from other air traffic while also allowing for sufficient space for small aircraft operations below that altitude without stringent air traffic control oversight.

Understanding the floor of controlled airspace is essential for pilots when planning their flights in terms of both navigation and compliance with air traffic regulations. It helps in making informed decisions regarding altitude, route selection, and communication with air traffic control, thereby enhancing overall safety in the airspace around busy airports like Half Moon Bay.
