Yeah, I agree, there's a lot to be tuned as well here.
But, just a quick example: As told in the other thread, I had to go from Littlestone to Le Touquet tonight.
So I measured the angle between those two 'waypoints' with respect to an eastwards course, came up with a number around 50 degrees, and added this to the eastwards course -> I had to head for approx. 140deg.
Afterwards, I had to fly a little eastwards (90°) in order to be able to head directly to the north towards calais after that. With little landmark reference at that spot, I used the distance measuring tool and came up with a number of 9-point-something miles eastwards from Le Touquet, so I had a rough idea of how long to fly to the east.
After that, It was just proceeding northwards... so yeah, the tools
are in fact handy. Though they need tuning, as you say
Regarding your example: Why not just do an airstart at the 'interesting part' ? I guess you're the same freak just like me who recognizes true missions only if they start
and end on a runway/an airfield
