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?

I (being European but not British) am used to the terms "track" and "heading". The abbreviations TT, TH, MT and MH seem universal (and are used by SD) – I've never ever seen TC or MC. Perhaps SD should avoid entirely using the term "course" if there is a possible ambiguity.

I second that!

To elaborate on what I posted earlier, see http://www.pprune.org/questions/305415-course-difference-between-us-europe.html
Let's banish the word "course"!

Bennett's 'Complete Air Navigator':

'Course is the direction in which the aircraft's fore and aft line is pointing expressed as degrees (as a three figure group) measured from the True Meridian, Magnetic Meridian, etc. In marine navigation the term 'course steered' has the same meaning, and in American aviation 'heading' is generally used.

I wouldn't argue with Bennett !

Maybe heading could be regarded as an instantaneous figure and course steered an average heading.

The heading can vary a lot in rough weather (at sea or airborne) while attempting to steer a course.

Anybody remember CDMVT ?

Course/Deviation/Magnetic/Variation/True.

No mention of heading.

It is my understanding that SkyDemon uses Track and Heading. If you can point me to anywhere it says Course, I will address the situation!

Tim, I found "course" here and there. Let me look into this over the weekend. "Call you back"

The word "course" appears mainly in the mobile ("in flight") documentation, but also on warning screens, in particular in the following documents:

• Getting started http://www.skydemon.aero/inflight/documentation/gettingstarted.htm
  
• Flying a route http://www.skydemon.aero/inflight/documentation/flying.htm
  
• Using the instruments http://www.skydemon.aero/inflight/documentation/instruments.htm
  
• Warnings http://www.skydemon.aero/inflight/documentation/warnings.htm
  

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.
