What does the magnetic compass display?

The magnetic compass displays the aircraft's heading relative to magnetic north. This means it indicates the direction in which the aircraft is pointed, measured in degrees from 0° to 360°. The compass is a vital instrument for navigational purposes, allowing pilots to determine their orientation relative to the Earth's magnetic field.

Understanding the function of the magnetic compass is crucial for effective navigation and maintaining the correct course during flight. While other instruments measure aircraft speed, rate of climb, and altitude, these parameters are displayed by different instruments such as the airspeed indicator, vertical speed indicator, and altimeter, respectively. The unique function of the magnetic compass as a directional instrument distinguishes it from these other instruments, highlighting its essential role in ensuring pilots can navigate accurately while flying.
