Thanks a ton, audiohavoc!  ;D Finally I know what all those abbreviations mean (that's why it has taken me so long to learn this stuff, I didn't have a clue what they meant). Just one thing: what's the desired course? Is it the listed heading in your NavLog?

Yes, it is the heading in the NavLog or the heading determined by looking at a sectional chart.
