HT-
Thanks for taking the time to consider this.
I was thinking of the plane on blocks because that's how they did it in real life. I figured it would add some realism, including the lack of the various situational dynamics. IOW, you'd get what the real guys got and have to draw your own conclusions.
OTOH, doing it in flight as we have to do now wouldn't be so bad if it wasn't so time-consuming to use. To experiment at different alts, you have to take the time to climb all the way up there. To experiment with different speeds, you have to level off and wait to build that speed. And you have to keep playing with your course and altitude to stay on target, especially as you varry the range. Set the target far out there and you have to be higher, etc.
So maybe the best thing would be to allow you to enter your speed and alt and POOF, there you are flying along under those conditions. From inside the plane, you can shoot. If you go to an external view, you can adjust your convergence in flight. What do you think?
