What is the minimum avionics equipment necessary to operate above 10,000 feet MSL over San Francisco International Airport?

• A. GPS and autopilot
• B. Transponder and encoding altimeter
• C. Flight director and terrain awareness system
• D. Weather radar and VHF radio

Answer: (B)

To operate above 10,000 feet MSL over controlled airspace, such as that around San Francisco International Airport, specific avionics equipment is required for safety and compliance with regulations. The minimum necessary equipment includes a transponder and an encoding altimeter. The transponder enables air traffic control (ATC) to identify and track aircraft within the busy airspace, which is critical for maintaining safe separation and situational awareness. It sends a signal that allows ATC radar systems to display the aircraft’s position, altitude, and other important information. The encoding altimeter provides altitude data that is encoded into the transponder signal. This information is imperative as it informs ATC of the aircraft's exact altitude, enhancing safety and coordination in a crowded airspace environment. While GPS, autopilot, a flight director, a terrain awareness system, weather radar, and VHF radios are all beneficial tools that can enhance navigation and safety, they do not represent the minimum requirements stipulated by regulations for operations in this type of airspace at altitudes above 10,000 feet. Therefore, the presence of a transponder and an encoding altimeter is essential for compliance with aviation safety standards in that operational context.
