Which instrument is described as being like a car's speedometer?

• A. Altimeter
• B. Airspeed Indicator
• C. Vertical Velocity Indicator
• D. Attitude Indicator

Answer: (B)

The key idea is measuring how fast the aircraft is moving through the air. The airspeed indicator does exactly that by using the pitot-static system to sense dynamic pressure and then display indicated airspeed. Just like a car’s speedometer shows how fast the car is moving, the airspeed indicator shows how fast the airplane is moving through the surrounding air, which is essential for performance, takeoff, and landing decisions. It’s not about altitude or how quickly you’re gaining or losing height, which is what the altimeter and vertical speed indicator measure, nor does it show the aircraft’s orientation, which is the role of the attitude indicator.
