It took a couple of weeks, but I'm comfortable manually launching the DG into orbit, docking w/ISS, and landing. Tex's tutorials really helped understand what was going on. Now I'm working on flying Atlantis into orbit on the Launch into Sunrise scenario.
First problem: the sim won't work with the default configuration. I had to go into the settings (not really knowing what I was doing) using the Scenario Editor to set the dx/dt, dy/dt, and dz/dt values to zero. They all read -1.J#, which seemed odd to me. Sitting on the launchpad, there should be no velocity in x, y, and z. After setting those values to 0.0, the sim works.
By using the Ascent MFD AP to get to orbit, and documenting the various attitudes and thrust vectors during the autoflight, I can manually achieve orbit at various heights. Not as well as the AP, but I can git 'er done.
Next problem: I've tried a wide variety of launch azimuths, recording the RInc outcomes on the Align Planes MFD, in order to eventually dock with ISS and/or Mir. The closest I can get for ISS is an RInc of 22.01 degrees at a launch Az =100 degrees, and for Mir, RInc = 55.51 also at Az = 100. I'm using the Ascent MFD to input the launch Az.
I'm mystified. There is a setting below the launch Az in the Ascent MFD for Orbit inc., Shouldn't I be able to enter an Az value which drives the Orbit inc. to the posted value in the information screen, i.e. 74.27 degrees for ISS, and 3.93 degrees for Mir?
Scrolling the AZ+ and AZ- keys yields a minimum Orbit inc. value of 28.6 degrees in the range from 88.8 degrees to 91.2 degrees Az. It's not possible, from what I'm doing, to achieve a Orbit inc. of 3.9 for Mir, and when I set the launch Az to drive the Orbit inc. to 74.3 for ISS (either to the NE or the SE), the resultant RInc turns out horribly.
Any help with the Ascent MFD, or any other ideas, would be appreciated.
