Hi to all, I am back with some new issues/questions.
I am still alternating between A7 and A9 (having completed A8), I arrived at the moment where you need to activate the LM before getting the PAD for the docked DPS burn.
here are the problems:
1) when I do the IMU coarse alignment I will enter into the AGC the LM O/I/M angles read on the LGC page of the PAMFD setting LVLH by pressing REF; in my case I have about these values:
LM O/I/M = 310.79 102.84 2.17
so I enter them as: V41 N20, +31079E +10284E +00217E
BUT: I see that only the FDAI on the panel 1 is moving, the FDAI on the panel 2 is not moving, still keep showing 0-0-0 degrees.....am I missing some cbs to power up the FDAI2 ???
if I then do V16 N20 I got more or less the same angles......BUT..
2)The FDAI reading is "weird" .... if i have to read the R_P_Y as for the FDAI for the CSM (with ROLL and YAW interchanged due to different MG set-up between the LM and CSM IMU axis) I can see/read the information displayed by V16 N20 not like (R-P-Y angles, as in the CSM) but as for (Y-P-R) .... still the attitude information that I "read" from the FDAI1 is a little bit different from what is displayed on the AGC; namely the "roll pointer" is about 2 degree ---- which seems to confirm me that in the AGC R3 is showing indeed Roll information) ---- the pitch is ok as it should be at about 103 degrees ---- but the yaw is about 50 degrees, looks like it displays 360-310=50 degrees .... not the 310 degrees as indicated by the register R1 .....
I tried to open the default scenery in the A9 historical missions (the one at T-6min to DPS docked burn) I saw both FDAIs are run and aligned but if I move the vessel to another attitude and I enter V16 N20 to read the angles on the AGC again I can see that the angles shown on the FDAI1 are not equals to the values reported in R1-R2-R3 in the AGC ....
last issue: in two saved scenarios, one before the RCS cold firing test and one before that, when I arrive to GET 048:00:00 (while steel busy to finish checklists items in the LM) i got the MCC message for SV update, I immediately go back to CSM (interrupting what I was doing) and set everything for get the uplink, but after pressing 2 on the MCC menu i don't get any uplink .....and more important I never get the burn PADs....
what is goin on? am I evidently missing some checklist item at the correct time? or can they be again some sort or "orbiter glitches"? or issues related to frame rates -> my PC.
out of the record I would like also to point out some other issues, I had with A9, but never on A8 and so far never on A7 (but A8 and A7 were/are with 2010P1 orbiter...)....sometimes while making time acceleration to x10 or x30 (more I can't go with my PC) all a suddenly I got NO ATT, RESTART, PROG lts ON on the AGC in the CSM ..... normally when it happens I just exit and re-start a saved scenario few hours earlier and the same issue doesn't happen again .... but still .... what could cause it? time acceleration seems to be the root cause surely....
last: now I am saving always using the scenario editor and pressing SAVE when I want without exiting the sim (as explained to me in this forum).
Thank you to take time to read me.
cheers, Paolo.
PS: compared the CSM the LM seems to be very complicate to handle ... hope to can manage it one day :-(
