Well, I'm either really brilliant at it, or, far more likely, people end up over complicating the navigation bit by obsessing on finding the one optimal bearing that brings you to both the desired Lat and Long at the same time.
Our ships are so fast in orbital cruise we can easily go around the planet twice in the span of a few minutes, when you have that luxury it's not longer expedient to focus on calculating that one bearing.
So I just simply focus on Latitude first, by moving only at 0 and 180.
When that is within a few minute deegrees, I do Long by flying 90 or 270.
When I'm within a minute or so I drop from cruise, you can't really control your drop so the last few km is spent hunting closer to the surface.
Of course real life navigation need to calculate the optimum bearing, but that's because of time it takes to travel and economies around fuel etc.

Is brilliant. although with my approach I'm halfways to the desired area by the time my wingman has finished typing in all the numbers.
And since I'm in VR, I have to use my phone, and a bug with my phone and the input fields used I can't enter negative coordinates.
