after the launch autopilot finishes work and puts me in orbit, how do i activate the other autopilot

 

[Kaito]

As of right now, there is no TLI (Trans-Lunar Injection) Autopilot. You need to do it "manually" using IMFD. Same for LOI (Lunar Orbit Insertion), and same for TEI (Trans-Earth Injection). Theres a neat little tutorial in the tutorials section that says how to do this using IMFD

 

[AlphAPollo]

okay, i saw the tutorial and tried it, but i don't get steps 1-4 of part two. can somebody explain me this steps please?

 

[Kaito]

You need IMFD. Download it before you do this. Then it should make much more sense

Cute, been there

Umm....Stupid question, do you have a link to get IMFD?

Thanks, should of looked there first.

i have IMFD, i just don't know how to load an autopilot on it.

 

[Kaito]

You dont load an auto-pilot into IMFD. You calculate the trajector, then hit the AB (auto burn) key.

 

[AlphAPollo]

how do i calculate the trajectory, and if i succeed doing this, i didn's see the AB button

 

[Kaito]

And that is where you read the tutorial

i looked over the tutorial, and when it says:

Step 3. Press MOD to modify the configuration.
(Here we are going to set the parameters for making IMFD use Apollo-like attitude correction which is more like a "point and shoot" configuration. The next few steps (Step 4 and 5) are optional but mandatory if you wish to continue with this tutorial.
Step 4. Set LambertAP mode to Apollo P30.
(Next step sets IMFD to do a more realistic Apollo-like burn as the real Apollo burns were done. The throttle-down of the main engines were cut offs to a thousandths of a second and this setting makes IMFD cutoff with the same accuracy).

i mess up. first: when i press MOD, does the screen usually changes, and i don't get step 4:

Set LambertAP mode to Apollo P30.

what do i have to do there?

 

[Kaito]

Start IMFD, and press MNU (its the upper left button). THen press the button that corresponds to "Configuration"

 

[AlphAPollo]

okay, that really worked but now i'm stuck in:

E. Set up the IMFD Navagation Computer to Calculate a Free-Return Lunar Interctption
......................................................
Step 26. Set the LMFD's Operation modes to: "Vel. Frame" by navigating between the 2 pages and useing "Nxt", "Prev", "Set", "(+)", and "(-)" buttons.

what the heck do i do here?

 

[Kaito]

aw man...i had problems with this too...um....
Press MOD until the page changes, then see Operation Modes. Change "Offset Disabled" to "Vel. Frame".

 

[AlphAPollo]

thx i'll try that

I found the tutorials for IMFD and AMSO very confusing, so you might want to try my 'IMFD/AMSO for dummies':

Editing AMSO's Autopilot

Sorry for bumping an old thread, but it's on the topic of AMSO's autopilot and therefore I didn't think a new thread topic was necessary...

Is it possible to edit AMSO's EOI autopilot such that a different Apogee / Perigee and orbital inclination/heading is achieved than the default setting? The idea is to fine-tune flight plans based on historical flights.

According to the AMSO User manual:

The autopilot for Earth orbit insertion will bring you to a perfect circular orbit at the nominal altitude of 101.4 n.mi. (187.7 km) for missions up to Apollo 14 and 90.0 n.mi. (166.7 km) since Apollo 15.
​

While these orbits work fine, what if I wanted recreate Apollo 8's flight more accurately and achieve a 98 n.mi x 103 n.mi. orbit? Or more importantly, achieve the right heading, which is about 4 degrees more due east than AMSO's generic orbit.

[Self-Edit] I was blatantly wrong about this... AMSO does not use a 'generic' launch heading. Upon investigating the Apollo 8 scenario file, the azimuth is set to the historical orientation, down to three decimal places. But thanks to boogabooga's input, I now know how to change this parameter if I wanted to.​

I tried changing the heading of the launch-site and spaceship in the launch scenario file, but all that did was increase the amount of roll the autopilot executed to maintain its original heading.

Cheers.
