Ok well if that can't be changed then I will have to live with it. Any one with any ideas on my deorbiting question?

 

[AtlantisOnline]

No one can tell me how to find the TIG for a deorbit burn. Also if -20k is the correct amount of altitude below earths surface for a deorbit burn.

The goal is -1.5° reentry flight path angle at 120 km altitude (EI), with EI being about 45° away from the landing site. IMFD can calculate you this.

Ok I figured how find out those info's on the IMFD but how do I use this to program my deorbit. I put in the values but where do I find the TIG and the Delta V. Also I am assuming the IMFD is in meters per second. Thank You

 

[AtlantisOnline]

Basically how do I work it to get the values I need such as DV

Also How do I find the Hint value?

Anyone?

I know it is time to Peapris (sorry for spelling) but when I try to add a value to imideatly jumps to 8K or around that [I checked and the adj button was on one]. It seems like it is more geared for interplanetary flight hence the name but how would i use it for data values for the ssu. This is still relating to deorbit.

I need you guys to answer for me to perform my deobit burn...thank you

Ever heard of just winging it? Or trial by error? Just set up a scenario that puts the shuttle on its final orbit and play around with different numbers. The great thing with Orbiter is, if you screw up no harm done, you just restart the scenario. You have been given the tools and the data to look for.

How do you get to the MFD with the Item and OPS buttons(GPC i think it's called)? All I have in the CRT MFD is "Up, OMS, HYD, SPI" and none of the MM screens or anything the manual talks about...:idk:

Are you supposed to download the GPC MFD and AutoFCS separately or something?

 

[SiameseCat]

In V1.25, the Item entries are done through the Orbiter's keyboard. You can get the displays by clicking on the Up button in CRT MFD.

But when I click "Up", all I get is a single line of text that says "000/00:00:00" in the top right corner of the MFD. Am i doing something wrong or is this a bug? :idk: Happens on both O2010 and 2006 for me.

On a sidenote... is the SRB smoke supposed to be brown and cover up the SRB flames even when seen from the front? Sorry if i'm annoying you.. lol.

If you're on the launch pad, that's normal (because the display aren't simulated). A few of the on-orbit displays work and that's it at the moment.

Ahhh, I see. I got it now. Thanks a lot for the help man.

 

[AtlantisOnline]

ok now when try to use the rcs it goes all crazy on me and fires in completely random directions from all ports at once. Why is this happening?

 

[SiameseCat]

That's probably the DAP; what mode are you in?

 

[AtlantisOnline]

I figured out the random firings now...it was when I tried to use the auto burn in interplanetary or the aoa hold in aerobrake. It was because I was using and autopilot that uses the rcs. Now I have anouther question...how would I activate the dap that controls the shuttle during reentry...in the shuttle fleet it is just the key d or b if forgot which but how do I do it in the ssu. Im off the check the scom but perhaps you guys could tell me an answer faster. Thank You

Sorry but there's no entry guidance whatsoever in SSU at the moment and that includes the DAP. De-orbit burn and entry/landing has to be flown manually.

 

[AtlantisOnline]

Okay. better start brushing up on those flying skills. Thank You

 

[AtlantisOnline]

Hey guys I was wondering if the auto fcs works with the ssu. Is there anything I need to change to make it work with it or is it completely incompatible. Thank You

As far as I can tell completely incompatible. If you want reentry guidance, you need to program it yourself.

 

[AtlantisOnline]

Ok Unfortunatly I'm not a programer so that battle is lost. If anyone has already programmed a reentry guidence and have a sudden urge to share it I'm right here. Thank You
