Which of the following is required equipment for operating in RVSM airspace?

Operating in Reduced Vertical Separation Minimum (RVSM) airspace requires specific equipment to ensure safety and accuracy in altitude reporting. The correct answer encompasses all required equipment, which includes:

• An automatic altitude control system: This is essential for maintaining precise altitude. It helps prevent altitude deviations that could lead to conflicts with other aircraft.

• Two independent altimeter systems: This redundancy is crucial for cross-checking altitude readings. Having two systems ensures that if one fails or provides inaccurate data, the other can still maintain safe altitude reporting.

• One altitude reporting transponder: This device communicates the aircraft’s altitude to air traffic control and other aircraft, which is vital for maintaining situational awareness and safe separation between planes.

Together, these components work to provide a safe operating environment in RVSM airspace by ensuring that aircraft can accurately report their altitude and maintain the prescribed vertical separation. Each piece of equipment plays a specific role in achieving this aim, making all of them necessary for compliance in RVSM operations.
