Question How to Take off shuttle Manually.

[ripley1]

This is what I used to get to "useful" orbit.
Lift off, once clear off tower ,roll (takes about 4.5sec with num pad 6)*,pitch up and follow the ascent MFD (BTW very useful tool),by SRB sep you should have around +15 degree of pitch,lower your pitch slowly to +10 degree until you altitude reaches around 120k,roll to HU position and keep the pitch around +20 degree,(by pressing X make your FOV bigger to see your vel. vector circle if you are not in VC view),vel. vector will slowly decrease to the 0 degree and by then your altitude should be reach around 180k and rising slowly,Watch the orbit MFD and Ap alt,the MECO is important to do precisely,because it can throw your orbit beyond fixible eccentricity,so once Per. starts to rise fast,try to cut engines off when Ap and Per figures are nearly the same.Make sure your Per. is at least above 120k By then you should have orbit good enough to perform OSM-2 to fix your orbit.
I hope this can help you. I learned from watching autopilot take off and so far this worked many times for me.Once you know how to establish stable orbit,next step is to practice initial roll to desired direction and altitude.

I had never tried the Atlantis but this thread prompted me to give it a whirl. I'm coming from a fair amount of experience with the default DG and TransX.

It took probably 4 or 5 tries to figure out the rate to pitch over to not end up with an Ap too high followed by not enough time to raise the Pe before arcing over to a return into the atmosphere. But then it clicked and I managed a single launch burn (various throttle settings) to a fairly circular orbit at about 200 Km agl and fairly close in plane to the ISS.

I used TransX to do a series of maneuvers still with the external tank attached, that combined both plane change and prograde/outward direction per burn to rendezvous with the ISS. The first maneuver showed me that the directional target in TransX shows a ship direction that is different than the thrust direction but after several short pulses of the main engine (still with that huge tank attached) i realized the transX target is very usable. It turns out that placing the little green "x" down from center (by pitching up a bit) to place the "x" on the second from outer ring places the thrust direction exactly as needed for the maneuver.

After a few orbits I was sitting parked 70 meters beside the ISS still with the external tank attached and 1 to 2 % fuel remaining in the tank. But with no LIN it was either I detach the tank or don't dock. What a waste of fuel. I decided to detach and dock but that left the tank floating around the ISS for the next couple of orbits.

If you're talking about the space shuttle:

1. 10 seconds into the flight, still at a 90 degree angle, start rotate the shuttle until 20 seconds in
2. 20 seconds in, pull back while still rotating to a 60 degree angle. Stop rotating at 25 seconds but continue to pitch if needed (You just have to level out on your own at this point)
3. 100 seconds in, pull back to a 40 degree angle
4. 130 seconds in, the SRBs will fall off
5. 150 seconds in, SLOWLY (I press "2" on the number pad two times) pull back to a 30 degree angle
6. 225 seconds in, do the same thing to a 20 degree angle
7. 300 seconds in, do the same thing to a 10 degree angle
8. 375 seconds in, do the same thing leveling horizontal with the earth
9. 450 seconds in, do the same thing pulling back to a -10 degree angle
10. 525 seconds in, do the same thing pulling back to a -20 degree angle

- You just have to look at your Orbit MFD to know when you're done
-And when I say a certain amount of seconds in, I'm talking about seconds from when you started the launch, not the time in the top right corner unless you started the launch just as the game started
-I usually finish with about 3 percent fuel left in the external tank. That doesn't matter, I just jettison it
- I use IMFD to fix the orbit I got into to a perfect orbit around the earth at usually about 350 km.

The Shuttle Fleet autopilot will usually place you in a lower-faster orbit so you can chase down the ISS more effectively. It usually takes around two days to get into position within one orbit away so you can do the final rendezvous maneuvers. I like my initial orbit to look something more like 200-220km altitude.

I am still unable to get in orbit successfully. Now i am trying with DG. i am looking for playbacks. Every time i liftoff with shuttle it starts falling whenever i use autopilots like prograde etc.

i have used this tutorial= [ame="http://www.orbithangar.com/searchid.php?ID=2455"]Atlantis Manual Launch[/ame]

Thanks All of you.

*facepalm*

Stop using the shuttle until you've successfully gotten a DG into orbit.

And RTFM. In the "Checklists" folder, run the scenario called "Mission 1 - DG to ISS."

Hit "F4" when the scenario starts, choose "Help" at the top of the menu, and do everything it tells you.

I have tried this, But as i reach the alt of 103 k (pitch 10 degree) it starts falling.

Okay, this will be my last post in this thread if you continue to ignore me and insist upon trying to get the shuttle into orbit without having the foggiest idea of how orbits work.

Have you even tried using the delta glider to get into orbit?

Use the DG and the Orbit MFD displayed (at least.) If by "falling" you mean the DG burns up and/or hits the Earth, you are shutting off the engines two soon. In the DG, it's REAL EASY to do one of these two things:
1) Get into orbit
2) Escape Earth

Thanks, Everyone who posted reply to this Thread.

Now i learned how to get in orbit. i used Deltaglider for learning, it was easy to learn with DG. Thanks Pilot7893, Hielor, -Pv- They all advised me to use DG after this i should try on shuttle

Once again, Thanks. :speakcool:

One reason the DG is easy enough for newbies is because although it's limited by Orbiter's mostly realistic mechanics, it's not a realistic spacecraft by today's state of spacecraft hardware. You are learning why it takes 20 years to train Shuttle astronauts, seven people to operate it, and a team of thousands to prepare, launch and support a mission. It's not THAT hard for Orbiter users, but it's much harder than the DG. The DG can go to Moon and Mars. The Shuttle cannot.
The Glider has the power and fuel to make LOTS of mistakes and still have fuel left for correcting those mistakes. The Shuttle has just enough power and fuel to do everything right once.

I agree with you.
