What is the purpose of the altimeter?

• A. To measure airspeed
• B. To measure aircraft altitude above sea level
• C. To detect wind direction
• D. To estimate fuel consumption

Answer: (B)

The purpose of the altimeter is to measure aircraft altitude above sea level. This instrument provides critical information to pilots, allowing them to maintain proper altitude for navigation, safety, and compliance with air traffic control regulations. By using atmospheric pressure as a reference, the altimeter converts pressure readings into altitude. When flying, it ensures that pilots can accurately gauge how high they are flying above sea level, which is vital during takeoff, landing, and while flying in the vicinity of other aircraft or terrain. This altitude information is fundamental for safe flight operations and helps prevent collisions with terrain and other aircraft.
