FAA Ground School Practice Test

What minimum radio equipment is required for VFR operation within Class B airspace?

1. Single-band radio and altimeter

2. Two-way radio, 4096-code transponder, and encoding altimeter

3. Basic radio communications equipment

4. None, radio equipment is not required

The correct answer is: Two-way radio, 4096-code transponder, and encoding altimeter

For VFR (Visual Flight Rules) operation within Class B airspace, the regulations specify that a pilot must have specific radio equipment to ensure effective communication and safe operation. The minimum required equipment includes a two-way radio capable of communicating with ATC (Air Traffic Control), a 4096-code transponder that allows ATC to identify and track the aircraft, and an encoding altimeter which provides altitude information. This combination of equipment is vital because Class B airspace is generally located around busy airports where there is a high density of air traffic. The requirement ensures that pilots can receive instructions from ATC and maintain situational awareness within that controlled environment, which is crucial for safety. The presence of a two-way radio facilitates direct communication with ATC, which is essential for receiving clearances and instructions. The 4096-code transponder improves the visibility of the aircraft on radar, allowing ATC to manage air traffic more effectively. Lastly, the encoding altimeter is important for ATC to track the aircraft’s altitude accurately, ensuring safe vertical separation from other aircraft.
