Hi
I know there are better MFDs for this but I am using Transfer at the moment because it's an easy way to familiarise myself with what's going on.
I have followed the instructions for this MFD and the first time I used it, it got me to the moon. However, on every subsequent use for some reason I am missing the moon. The problem occurs towards the end of the burn when my orbit is extending out to match the HTO. When my orbit is about halfway, the predicted position of the moon suddenly starts to move away from the gray line, out of the HTO, such that by the time the burn is complete, the moon's final position is 60-70 degrees ahead of the gray intersection line, and obsviously there's nothing I can do.
I have tried this several times now and keep getting the same result. The consistency of the error suggests there is something I'm doing wrong but I can't think what it is.
Anyone else know?
