Flight simulator -- what is heading?

[Suwaneeguy]

Please explain what the purpose of heading is in the waypoint setup.
I assume the heading is based upon where the next waypoint is.
What if I do not even set it?

Heading is the direction the Phantom will face when it reaches that waypoint. It will pivot around to face the heading you program before turning back to point towards its next waypoint and flying off in that direction.
