There appears to be a difference between SD (or perhaps British?) and American /International /ICAO terminology. Apparently:
SD "track" = ICAO "course"
SD "course" = ICAO "heading"
I can understand that with UK roots and a large UK user base, SD had chosen to adopt UK terminology.
However it can be confusing for those having been trained, and used to flying, elsewhere.
I doubt there is any answer to this.
Comments, anyone?

Here is what I've been brought up to use:

Heading is the direction in which the longitudinal axis of your aircraft is pointing.

Course is the direction of the current leg you are following on your route.

Either one can bei true or magnetic.

... and 'track' is the direction the aircraft is actually making good which, like 'course', can be true or magnetic but, by definition, heading is always magnetic. Except in 'nil wind' conditions, 'track' and 'heading' are always different. If you happen to be flying very accurately, then 'track' and 'course' will co-incide, but they are otherwise almost always different.
