What does the term "heading" refer to in aviation navigation?

In aviation navigation, the term "heading" refers to the direction that the aircraft is pointing in relation to magnetic North. This is a critical component of navigation, as it helps pilots understand the orientation of their aircraft in relation to the Earth's magnetic field. Heading is important for ensuring that the aircraft is on the desired flight path and can be affected by wind, requiring adjustments for accurate navigation.

Knowing the heading allows pilots to make precise adjustments to their course to compensate for any deviations caused by factors such as wind or turbulence, ultimately helping to maintain the intended route. Understanding and correctly interpreting heading is essential for safe and effective flight operations.
