Flight Question How can I find launch windows?

About iV, it seems you didn't watch the pictures. Forget about Burn Vector inward V: we already discussed the doubt (asked by me) and Jarmonik sealed it. I'm talking about inherent V. If you neglet this component (as TransX do), some people could believe that a "perfect" off-plane (let's say 90°) is spending the same energy as a coplanar transfer. But of course, it's not like that. That's all I wanted to say.

I had forgotten that was you in that other thread. I was trying to explain why iV was higher in an off-plane transfer, and wanted to ensure that TransX users understood that iV can mean Inherent Velocity, not Inward Velocity, in IMFD.

You are absolutely correct, and when calculating the efficiency of a transfer the insertion cost must be considered - and the higher the RInc at eintercept, the higher the insertion cost.

I will point out that insertion cost can sometimes be ignored - if you will using a braking method that doesn't use the engines, such as aerobraking.
