What is the primary function of an airspeed indicator?

• A. To display the aircraft's current speed relative to the surrounding air
• B. To measure the altitude of the aircraft
• C. To control the aircraft's pitch and roll
• D. To monitor fuel consumption

Answer: (A)

The primary function of an airspeed indicator is to display the aircraft's current speed relative to the surrounding air. This measurement is crucial for pilots since it provides essential information about the aircraft's performance and aerodynamic characteristics. The airspeed indicator helps pilots determine whether they are flying at safe speeds for various phases of flight, such as takeoff, landing, and maneuvering. By informing the pilot of the flow of air over the wings, the airspeed indicator assists in ensuring that the aircraft remains within its operational limits, preventing stalls and optimizing fuel efficiency. Maintaining an appropriate airspeed is vital for maintaining control of the aircraft and ensuring safety in various flight conditions. Other options do not fulfill this primary function; they focus on aspects that the airspeed indicator does not monitor or display.
