Don: page 56 of the Jeppesen Professional CR Computer Instruction Book
— DEFINITIONS — Course = "Intended direction or path of travel over
surface of the earth with respect to north." In the case of a VOR leg,
"intended" is the operational word. While a "heading" " … is any
direction in which the longitudinal axis of the aircraft is pointed,
with respect to north" (re: Jeppesen), it also means the correction one
ends up with after accounting for the wind (if any). If you have an old
Weems Plotter you will note the sequence to follow to come up with an
actual compass reading to adhere to after takeoff is printed on it so
guys like me (an attention span much smaller than the size of my
wristwatch) can refresh each time we do a flight plan.

All the best,
