First, I think this is still a good primer on the EMS: http://nassp.sourceforge.net/wiki/Entry_Monitoring_System (disclaimer, haven’t actually read it in a while)The numbers on a pad that relate to pitch and yaw trim get fed to N48. Is there anything else I need to do post SPS burn to trim with thrusters other than nulling out any small dv on the EMS.
Indeed that appears to be a typois there a small typo on the checklist (MAG instead of MGA)
That confused me too, initially. This comes down to understanding what V48 - DAP settings - is really about, and even then it’s a bit strange. The first register has 5 ”spaces” (A-E) each of which can be a 1 or 0. The checklist here expects you to know what A will be, depending on whether you have the LM attached etc. B and C relate to how many +X thrusters fire if commanded to translate that way, specifically for ullage. What you put there depends on what the burn requires, and the flight plan will generally state a) if ullage is required, b) how long, and c) whether 2 or 4 jets. If 2, then B and C will be either 1 0, or 0 1. Your pick, depending on which thruster pairs you want to use (generally those with more fuel I guess).11 or 00 will mean 4 jets. D is the deadband (low or max) and directly impacts how tightly the spacecraft will stick to its assigned attitude. Finally, E is the rate it will move under DAP control (I am typing this all from memory, so there may be some inaccuracy but hopefully enough to get you roughly acquaintedit's also not clear here what i need to enter given the first part of setting an SPS P40 burn up. It looks like 5 green digits will be entered into the computer but actually, only 2 get entered, as there are no ABC keys.
What I do is this: if I only get a new CSM weight, and not a new LM weight, I will assume the LM weight is still valid, and therefore only change R1 - V21E. That leaves R2 alone. You just Pro from there. V24E means you have to change both, which you do not want to do (unless you remember what was already in R2 before it blanks out).1) I filled out 62745 in R1 from the PAD but there is no sign of the LM weight but there is a default in R2 of 33528. The problem is in prev checklists each R1 nd R2 has an ENTER in the checklist so for the one below , before i press PRO on the "Load CSM and LM Weight" checklist item, should I press enter twice 1) to accept R1 and 2 to accept the default thats in R2 before the checklist gets to hitting PRO on the computer.
is the ullage fire automatic at the start of the burn or is it something you have to manually trigger .There is a ullage yellow line in the checklist i remember I just PROd past it. Also there were a few times lines saying to check MTVC (manual thrust vector control) so i suspect answering my own question this is what the ullage button is for but the checklist didnt say to press it.
I have the same throttle/stick, as well as rudder pedals. I think I had the same issue as you did. I think I experimented with plugging some in or out, but ultimately the way I managed to resolve the problem was buying a cheapie joystick and unplugging the others. The advantage of the cheapie is that it has a yaw twist function, like the real RHC. I use the numpad for translation. Seems to work very well for me.Thanks Indy, understood. I'm just using the keypad as my warthog and saitek peddles I cannot get to work. I have disabled joytick in std orbiter but when setting the axis numbers in NASSP it always seems my yaw peddles are causing rolling or translation. Any hints or should i unplug the throttle and peddles and just have the joystick.
