I'm new to Orbiter and i'm running into a few problems here and there. How do i program the Ariane 5 (by Well & No matter) autopilot to get into orbit? I know the commands, but i can't get the profile right. I always end up in the ocean (not above it, IN it, lol). I managed to get the roll program right, but i can't get the pitch program working. This is what it looks like right now.

Code: 
-15=PlaySound(SoundW-ariane5DDO.wav)
-11=PlaySound(SoundW-ariane5ar503v112.wav)
0=engine(0,100,7)
06=PlaySound(SoundW-ariane5EAP.wav)
13=roll(5,88,20,83,1)
15=target(150)
30=pitch(83,30,60)
42=PlaySound(SoundW-ariane5Pnorm2.wav)
90=pitch(30,20,30)
120=pitch(20,20,20)
138=PlaySound(SoundW-ariane5Separation-EAP.wav)
140=pitch(20,22.5,20)
159=PlaySound(SoundW-ariane5Pnorm2.wav)
160=pitch(22.5,22.5,40)
170=fairing()
170=PlaySound(SoundW-ariane5Larguage-Coiffe.wav)
220=pitch(22.5,10,30)
230=pitch(10,10,240)
250=PlaySound(SoundW-ariane5Pnorm2.wav)
350=PlaySound(SoundW-ariane5Pnorm2.wav)
469=PlaySound(SoundW-ariane5Pnorm2.wav)
470=pitch(10,0,20)
490=pitch(0,0,20)
510=pitch(0,0,100)
533=engine(100,0,2)
534=PlaySound(SoundW-ariane5stopEPC.wav)
535=engine(0,0,1)
549=PlaySound(SoundW-ariane5EPC-sep.wav)
550=jettison()
560=PlaySound(SoundW-ariane5Pnorm2.wav)
 
Are you sure that the roll programm works correct? I had problems with that many times.


Or try this:
Code: 
-15=PlaySound(SoundW-ariane5DDO.wav)
-11=PlaySound(SoundW-ariane5ar503v112.wav)
0=engine(0,100,7)
06=PlaySound(SoundW-ariane5EAP.wav)
13=roll(5,88,20,83,1)
15=target(150)
30=pitch(83,30,60)
42=PlaySound(SoundW-ariane5Pnorm2.wav)
90=pitch(30,20,30)
138=PlaySound(SoundW-ariane5Separation-EAP.wav)
140=pitch(20,22.5,20)
159=PlaySound(SoundW-ariane5Pnorm2.wav)
170=fairing()
170=PlaySound(SoundW-ariane5Larguage-Coiffe.wav)
220=pitch(22.5,10,30)
250=PlaySound(SoundW-ariane5Pnorm2.wav)
350=PlaySound(SoundW-ariane5Pnorm2.wav)
469=PlaySound(SoundW-ariane5Pnorm2.wav)
470=pitch(10,0,20)
533=engine(100,0,2)
534=PlaySound(SoundW-ariane5stopEPC.wav)
535=engine(0,0,1)
549=PlaySound(SoundW-ariane5EPC-sep.wav)
550=jettison()
560=PlaySound(SoundW-ariane5Pnorm2.wav)
 
Yeah, the roll program is working like a charm.
I have to go out now, but i'll try that as soon as i return, then i get back to you. Thanks in advance.
 
Looks to me like you're pitching waay too early. 20 degrees pitch at only 1 and a half minutes into flight? I don't think you're gaining enough vertical velocity early enough into the flight so you don't fall back. I'm not at my home coumputer right now so I can't try it though.
 
I was able to reach orbit manually (altought it was considerably higher than what i wanted). Pitch was 30° at T+100. I'm gonna try to program the autopilot to follow a similar profile. Anyone knows a way to calculate the pitch program?

Ok, after changing some parameters i think i might have found a bug. It seems like at this point "30=pitch(83,30,30)" the rocket turns in an uncontrollable spin for some reason. Has anyone ran into that?
