What is the floor of the controlled airspace over Firebaugh Airport (F34)?

The floor of the controlled airspace over Firebaugh Airport (F34) is established based on the specific airspace classification surrounding the airport and the altitude regulations that apply in that region. In this case, controlled airspace typically begins at a defined altitude above ground level (AGL) to ensure safe and orderly traffic flows.

For Firebaugh Airport, the controlled airspace often begins at 700 feet AGL, which is consistent with the standard floor for Class E airspace in many regions of the United States where an airport lacks an operating control tower. This altitude allows for appropriate vertical separation between aircraft operating under Visual Flight Rules (VFR) and those under Instrument Flight Rules (IFR).

It's essential to understand airspace classifications and their corresponding altitudes, as they dictate how and when pilots can operate within those areas. Other options represent altitudes that do not match the regulatory requirements for controlled airspace at this specific location, thereby making them unsuitable answers in this context.
