In navigation, what direction is indicated by 0 degrees?

In navigation, a bearing of 0 degrees indicates true north. This is a standard convention within the navigational reference system, where directions are defined in degrees ranging from 0 to 360. North is represented by 0 degrees, and as you move clockwise from that point, you reach east at 90 degrees, south at 180 degrees, and west at 270 degrees. Understanding these directional bearings is crucial for pilots and drone operators to navigate accurately, particularly when planning flight paths or conducting maneuvers in controlled airspace.
