Not sure if applicable to Apollo 15 (or whether there were any hardware changes meaning the switches should vary) but have you tried cross-checking the Apollo 11 Operations Checklist, page F10-20? https://history.nasa.gov/afj/ap11fj/a11-csmocindex.html Also, the Apollo 15 CSM G&C Checklist has...

Hi Folks. Stumbled across this non-Orbiter application: external FDAI project. https://github.com/jabadiagm/Bola8 I’m not familiar with python or its interface but this appears to be a very nice graphical depiction of the FDAI. Whether it can be interfaced with other software to make it useful...

Regarding the LM obscuring the stars, this is at least true to the real thing. From the post-flight debrief: Ground-supplied gimbal angles were used rather than those from the onboard computer. This technique was devised because computer solutions are unconstrained about the optics shaft axis...

Max-Q I think most people agree rendezvous is daunting. So perhaps a few general resources to help you get started: I found this old video helpful to describe the process (eg what is CSI, CDH etc): This site also breaks it down well: https://history.nasa.gov/afj/loressay.html A recent...

Just a small note for closure, got a new joystick and the noise in the yaw axis is no longer an issue. But the experience did help me continue to understand the interesting and nuanced ways in which manual spacecraft control is effected, and the differences between CMC and SCS control modes. I...

Thanks indy, I am using the prebuilt modules and doing my own builds is not within my capability unfortunately. I appreciate your other proposal but I agree it is preferable not to change code to cater for this one-off situation. I think it is pretty clear that, if nothing code-wise has changed...

Yeah, thanks for the suggestion. I did that and I’m now fairly certain the issue lies with my joystick, which has perhaps deteriorated and is exacerbating the yaw effect. That said, I don’t know if there is an underlying issue that is contributing. What I have noticed is that, in CMC mode, the...

Thanks for weighing in, I appreciate I was a bit fluffy with the details. To expand: Auto RCS all enabled on Panel 8, all other switches configured normally (in the default state upon scn loading) DAP Load was 11103, 11111 I’m trying to use the procedures from the Apollo 11 Launch Operation...

Hi team Using the latest build (1678) and the default mission scn (Apollo 11 - 05 - Before SIVB Sep), I’m practising TD&E. I’ve noticed that after CSM/LV sep, and upon commencing the pitch up move under CMC control (pitch accel cmd), the pitch-up induces a noticeable yaw rate, much more than...

Hi and welcome. Have a look at this thread, for a first try: Thread 'NASSP: P23 Program Explanation' https://www.orbiter-forum.com/threads/nassp-p23-program-explanation.36210/ Most of us have struggled with P23 when starting out, but threads like the above should answer your immediate...

The problem is not limited to your system, I think the lack of landmarks is a function of the Orbiter Beta. While initially a bit frustrating, it is actually a great opportunity to utilize the high quality textures, and increase realism, as ggalfi notes. It is actually quite enjoyable (for me...

Thank you both. @jalexb88 I confirm I have 100+fps standing on the pad in the VC, and the workarounds indeed work so no issues there. The new clicking method makes sense. (I accidentally noticed it with the SPS gimbal thumbwheels but could not figure out what was going on.) I’m happy to work...

Hi Team Just wanted to draw a couple of anomalies to the VC developers' attention. Not sure if this is unique to my system. These observations were made while sitting on the pad pre-launch: 1) FDAI 1 error needles slowly disappeared. After a while it became evident this was because the 8 ball...

That is an explanation of what “F 50 18” actually means in plain language. Breaking it down even further, a flashing (“F”) Verb 50 means “please perform.” Noun 18 is the FDAI RPY angles for the auto manoeuvre. Pressing PRO while there Is a F 50 18, and while CMC is in AUTO, will cause the...

The TIG TPI you receive from the lunar ascent PAD is an estimate, provided for the purposes of setting up the CSI (and following) manoeuvres. The TIG is refined over the course of the CSI/CDH process, as a result of the LM updating its knowledge of its own and the CSM’s state vectors. The...
