heading indicator
A heading indicator is a navigational tool used in aviation and marine contexts to show the direction in which a vehicle is facing. It typically displays the heading in degrees, ranging from 0 to 360, with 0 representing true north. This information helps pilots and sailors maintain their course and make informed decisions during navigation.
In aviation, the heading indicator is often part of the cockpit instruments, working alongside other devices like the altimeter and compass. In marine navigation, it assists sailors in steering their vessels accurately. Overall, the heading indicator is essential for safe and effective navigation.
