What instrumentation is required for VFR flight?

For VFR (Visual Flight Rules) flight, the required instrumentation focuses on essential flight data that allows pilots to navigate safely under visual conditions. The correct answer includes an altimeter, airspeed indicator, magnetic compass, and engine instruments.

The altimeter is critical for monitoring altitude above sea level, which is essential for maintaining safe separation from terrain and other aircraft. The airspeed indicator provides crucial information about the aircraft's speed, helping the pilot to operate within safe flight parameters, especially during climb, cruise, and landing phases. The magnetic compass is a primary navigation tool that enables pilots to determine their heading relative to magnetic north, aiding in navigation and situational awareness. Engine instruments, which typically include indicators for oil pressure, temperature, fuel level, and RPM, provide real-time data about the aircraft's performance and operational status, which is vital for safe operation.

While other options may include useful or advanced instruments, they do not meet the legal minimum requirements for VFR flight.
