What is the purpose of using a magnetic compass in flight?

The purpose of using a magnetic compass in flight is to offer directional heading relative to the Earth's magnetic field. The magnetic compass is a vital instrument for navigation, providing pilots with a continuous indication of their heading as they fly. This is essential for maintaining the intended course and making adjustments when necessary, especially in visual flight conditions.

The compass works based on the Earth's magnetic field, aligning itself to point toward magnetic north. Understanding the compass reading allows pilots to navigate effectively, ensuring they remain oriented and avoid disorientation during flight. The reliance on magnetic north is crucial as it differs from true north, thus pilots must also be familiar with magnetic variation in their area of operation for accurate navigation.

While other instruments in the aircraft may provide altitude information, assist with engine performance, or offer insights into wind direction, the magnetic compass specifically focuses on providing directional information, making it an integral tool for all pilots navigating in the airspace.
