I need some tips. Help me save myself from pulling up the default docking MFD and cheating. I get to the MC4 burn, and all is well. Testing out the results of the burn and just monitoring to see what happens, I'll end up around 500 feet below the ISS, and less than 1.0 on the R based on the...

So it's called the line of site rates display....didn't think it would be that easy coming from a government agency. 😄 So how is it used? Do you put the DAP in lvlh alt modes then use rcs translation? Assuming top and bottom is prograde and retrograde, or is that the z axis?

What is this called? Anybody have any tips how it's used when rendezvousing? I've managed to meet the ISS at what seems like a reasonable distance and rate of closure, but I'm not sure how to visually get from there, to station keeping. I see in videos this is used, but I'm not sure how. I...

Oh OK. I thought we were supposed to only use spherical gravity. I'll play around with changing both to non-spherical gravity. Thanks.

Thanks for explaining that. I do have one follow up question. When I set up the STS-101 FDO mission file, I didn't understand which generic plan to use. I looked at them, compared them to known good scenarios/missions, and picked PlanD. After recently looking at the plans again, I think my...

Thanks for the info! It's a STS-101 scenario I'm playing around with. I just checked, and I have spherical gravity selected for both the sim and the FDOMFD. I did use historical TLE's for the scenario/mission creation, and I'm using the historical launch time. I'm not using a huge amount of...

Curiosity question for anyone who might know. I'm playing around with an ISS rendezvous scenario, where using good historical TLE data, and historical launch time, the rINC is pretty stout; about 0.53 degrees. I'm guessing IRL yaw steering would have negated much of that. My question is what...

@GLS Curiosity question, not a pester either, as I know you're basically a one man show doing God's work. Will the hydraulic flight surface test that occurs just under 4 minutes to go in the launch countdown be in version two of the SSV? Would be cool to see. I always jump out and watch the...

Thanks that clears things up for me. And I heartily agree, that re-calculating before each burn is an absolute must for an accurate PAD.

So for example, after MECO/dump you could set up everything for the OMS-2 burn, fix the sunset TIG and correct Ti DVZ, and then save these changes as a FDO config under a new name. You could then theoretically use the newly named config, by deleting maneuvers and recalculating as usual along...

One more question while I've got you on the line so to speak. I've read the FDO manual about 20 times, and learn something new each time. What is the reason for making all of the saved files? I can see making the first save before OMS2 to lock in the TIGs for sunset timing, and Ti velocity...

When rendezvousing with a target using the FDOMFD, which burn would you typically stop using the FDOMFD, and begin using SPEC 34? I thought it would be the NH burn before the final NC burn, but I'm getting "interesting" results, and ran out of time last night to explore further. Does this AI...

I think a good thing to do at this point is to pull up one of the videos @Geoair2 has posted a couple pages back, and watch what they're doing with the MM's and the FDO data. It takes a little drunk monkey button pushing initially on your own to kind of learn the process needed in the...

I've been playing around with the SSV mission editor today. Opened up the STS-101 mission that defaults, and walked through the SSV manual section by section. It all looks pretty straight forward, until you want payloads, but for me, payloads are a down the road thing. So I tested and saved...

Oh, so at the very least, save once so as not to overwrite the original mission. I was poking around for the actual checklists, and they are a bit much for me. Very interesting, but kind of like drinking from a firehose. I did find what looks to be a good compromise. For the Flightgear...
