I have a question:

How i can know my currents ejection and phase angles?

Thx.

Well, I make sure nobody's around (so I don't make a fool of myself, measuring angles on a computer display), go to the map view, center my view on the north pole of the body around which I want to measure an angle, and use my transparent protractor (un rapporteur, en français)

If it seems too rustic to you, I believe there are a few plugins out there that can do the measuring for you... just look them up.

I basically have the same problem (I guess all of us who started to play around with the NERVA have it...), although I hadn't measured the angle covered during the burn... 40°, you say?

Well, since the ship's mass changes during the burn, the burn itself is actually more and more efficient, meaning the change of velocity gets exponentially quicker. So to do things right, you'd have to burn more than 20° before the theoretic burn point; exactly where could be told us by a bit of messing around with expoenential/logarithmic equations, but yeah, I guess burning 20° before the theoretic burn point should be a good correction already.

Hmph, frustrating. Suppose I'll have to simply trial-and-error the burns to see how much deviation I have from the burn angle once I reach ejection velocity? I noticed it was about 30 degrees on a burn with a different craft... it had the same burn problems as my current craft. I'll watch closely and learn to spam the quicksave function, which I have never before utilized...

I'm scared... What do I do with the numbers it gives me!?

[Trebuchet-Launch]

To correct a bad ejection angle, you want to burn radially in or radially out. If you overshot the ejection angle, you probably want to burn radially out.

All this math is way over my head. Haha

This post is a bit old. I'm right if I guess that manuever system does this work automatically? Or I'm missing something?

The maneuver system can help you "walk onto" a target from your current position, but that might not be the best or most fuel-efficient way to do it. Olex's calculator helps you figure out when and where to plot the start point for your maneuver to get the most efficient one possible.

Say, do you think it would be possible to add a feature where you can input your orbital altitude and the body you are orbiting and it can tell you what your transfer angle should be? say if I happened to be orbiting jool at 1000km and i wanted to know my transfer angle to tylo, it would be really handy to input the variables and get an answer. Perhaps I would need to put in my apoapsis and periapsis... or it could just assume a circular orbit...
