Hello-
I am using Orbiter 2016 with AMSO and Aerobrake MFD. I have an Apollo mission returning on a perfect 6.5 degree reentry angle and I'm trying to use Aerobrake MFD to better hit the landing target.
For re-entry, I point retrograde with heads down, so that I pitch "down" (away from earth) to a positive AOA to generate lift. That is working OK- the more I pitch that way, towards positive AOA and away from the ground, I generate more lift and my vertical speed trends positive. The same is true with the opposite, more negative AOA and my sink rate increases and G loads build up.
The prediction screen on AerobrakeMFD seems to have this backwards, pitching with more lift/positive AOA causes the trajectory line to shorten and max G to increase, wheras less lift/negative AOA makes a prediction that corresponds to more lift. Something is inverted, either the input aerbrake MFD uses, or AMSO using some atypical coordinate system that confuses aerobrake MFD.
Does anyone know what might be wrong, or how to fix it?
Thanks
