I remember it quite simply as...
1. TAS/HDG -
What's happening inside your cockpit. The HDG is what you maintain to counter the drift caused by the wind.TAS is basically your ASI indication corrected for xyz...
2. TR/GS -
What's actually happening on the ground. TR is the line you're describing on the ground AFTER the wind effect. GS is the speed you're actually making over the ground.Remember the stuff about a tailwind comp adding to your groundspeed, while a headwind comp slowing you down, or increasing your time to destination..?
Are you saying that with TAS placed with a HDG it will give you your GS and TR? And visa versa?
that would be provided you're given W/V. When you have to
find W/V, it goes the same way, only this time use the two sets of friends- TR/GS and HDG/TAS, to get the winds affecting all the mayhem !
