Aviation instruments are devices used in aircraft to provide essential information to pilots. These instruments measure various parameters such as altitude, speed, direction, and engine performance. Common examples include the altimeter, which indicates altitude, and the airspeed indicator, which shows how fast the aircraft is moving through the air. These instruments are crucial for safe flying, especially in poor visibility conditions. They help pilots navigate and maintain control of the aircraft. Other important instruments include the compass for direction and the attitude indicator, which shows the aircraft's orientation relative to the horizon.
