What is the height of the Class D airspace over Livermore Airport?

The height of Class D airspace typically extends from the surface up to a specified altitude, which can vary by location. For Livermore Airport, the Class D airspace extends up to 2,900 feet MSL (Mean Sea Level). This altitude is designed to provide controlled airspace for the safe operation of aircraft near airports with a control tower.

In this case, knowing that the Class D airspace is established to manage traffic and ensure separation between controlled and uncontrolled airspace helps confirm that 2,900 feet MSL is correct. It offers sufficient vertical space for arriving and departing aircraft while maintaining safe operations in the vicinity of the airport. As such, this option accurately reflects the regulations governing the airspace surrounding Livermore Airport.
