Hi everyone, How could I rendezvous to the ISS using the SPEC 34 display? I type in ITEM 28 EXEC to calculate the burn solution, are there any other steps to take? I have taken a look on SCOM and FDF but still can't understand how to do it. Thanks for any help.

So I managed to engage the entry DAP but the plane just keeps rolling on 0 deg. pitch. It doesn't do anything else. MM304 is entered, DAP is set to A/AUTO/PRI. Is this a fault in the scenario or in a bug. Scenario used: STS-107/Deorbit. Thanks

I typed in OPS 304 PRO on the GPC, but still nothing happened. The shuttle is at -60 deg. AoA at EI. If I did anything incorrectly, please tell me. BTW, is there supposed to be a display of entry trajectory, because sometimes my CRT just goes blank when I enter OPS 304 PRO Thanks.

The speedbrake opens about 80-90% right above KSC at Mach 1 and in an altitude of 40k-50k ft, i.e in the TAEM phase. I use joystick NOTE: I used the STS-107 entry interface scenario. BTW, How could I enable the reentry DAP which holds the AOA at 40 deg.? Thanks.

Great project developers! There is a problem during TAEM, where the shuttle opens the speedbrake and then the space shuttle stalls and goes out of control. Other than that, great improvements, loved it!

1) You could do only a single burn using the XXXX MNVR EXEC displays. To be specific, on the setup of the next burn, EXEC doesn't display when T-15 seconds to ignition. 2) All STS-107 scenarios except the launch scenario crash, because of missing config file. I have posted the part of...

Hey orbitingpluto, Thanks for the MFD, I was looking for an MFD to calculate dV targets. Much appreciated. :tiphat: BTW, blixel, your spreadsheet works great too.

Hey blixel, Cheers for the effort but I currently use C3P0 spreadsheet. So I will try it and tell you the results.

Thanks Uruwmpe for the solution really helped. :cheers:

Hey everybody, Is there a simple way to calculate the TiG in the OMS MNVR EXEC displays. I usually divide the ApT value by 60 and then add it to the MET but it overshoots. So any help would be appreciated. Thanks.

Well, I think I have to go with the solution I posted from the link I found, because I have tried it and it is really close to the target altitude. So thanks for your help.

Hi MJR, This is very complicated. Besides, my calculator can't take all of this equation. However, Urwumpe stated that the Vis Viva equation helps calculating delta V. Here is the link: http://orbiter-forum.com/showthread.php?p=391119&postcount=33

Sorry for asking many questions, but this is really getting complicated. My answers are like in the millions, having done the steps just like you mentioned. Can you solve this: TA=456 km SA=103 km And please try to explain as in depth as possible about the steps you did. Thanks.

Hi Kubala, Could you please explain the dV2 formula (at the bottom of the page) on your thread? Thanks.

Thanks guys for your effort, but I think I found the answer. It is basically a rule of thumb. dV=Starting Altitude (nautical miles)-Target Altitude (nautical miles)*change in velocity-2. So lets say the starting altitude is 103 km (56 nm) and target is 320 km (173 nm). 173-56=117 nm 117*2...

Yes. ---------- Post added at 01:17 AM ---------- Previous post was at 01:12 AM ---------- Is the G value the gravity or the gravitational constant? ---------- Post added at 01:18 AM ---------- Previous post was at 01:17 AM ---------- Ok, I will take a look at it.

Hi C3PO, I have tried Equation MFD but it is very complicated, TBH. N_Molson the calculator really helped and I am going to test it. MJR, I have taken a look at Tsiolkovsky rocket equation but the part about m0 and m1 I am really having trouble with them. What I mean is that how am I...

No, they are automatic. I just have to insert the required data (dV, TiG etc...)

Hi, Is there a formula that could help me calculate the delta v for change in orbital altitude. I need this for the OMS burns in the SSU. After MECO, I end up with an altitude of about 103-110 km. I would like to raise it something like 320 km. How could I calculate the Delta V for this...

Hello, I have had trouble with the TORF (Twice Orbital Rate Fly-around) after undocking from the ISS. How could I do a good TORF using the RPOP MFD? Is UNIV PTG MFD related to it? Please, try to explain in-depth as possible Any help would be appreciated.
