FCOM disagrees with Aircraft

[STR]

I'm flying a CLS A330-300. The FCOM tells me to set the flaps to 14 and gives me a vr of 155. The A330's flaps only go up to 4. The take off setting is 2. The FMC gives me a VR of 131. What should I do in this situation? Also, the FMC gives me a cabin alt of 7777, while the FCOM gives 8123 or something. I know that that part is irrelevant, but it's still a little irritating.

Also, there will be times when there is pretty blatantly turbulence in FSX(aircraft bounces up/down or left/right/whatever) and the FCOM says no turbulence.

The V speeds for the A330 are included in the configuration (by me) and are very approximate -- I couldn't find A330 V-speed tables on the internet (I guess because they are so computerized that old fashioned tables are obsolete.) They are included because I use Thomas Ruth's A330-200 and they give me ballpark figures -- the airplanes have none at all.

If you have an A330 implementation that gives you V-speeds it's certainly more accurate than what I put in the A330 config, which is advisory only. If you would like to delete or alter them, edit the file A332.cfg in the FSCaptain\Aircraft folder and see Appendix 4 of the User's Guide for an explanation of how the speedcall lines work -- or just delete the speedcall lines and the FCOM won't trouble you with V-speeds.

Also, the FMC gives me a cabin alt of 7777, while the FCOM gives 8123 or something. I know that that part is irrelevant, but it's still a little irritating.

Are you using FS9 or FSX? The answers are dramatically different depending on which you have. The FCOM reads the cabin altitude from FSX, whereas for FS9 it just computes its own approximation. If you have FSX then your FMC isn't reading from FSX and computing it's own by a different calculation than FSX uses. If you have FS9 then the FMC is using a different calculation than the FCOM does (no surprise there!)

FS9 does not simulate pressurization systems at all.

RE: turbulence the FCOM reads the G force factor from FS and determines turbulence by intensity and frequency. It often lags behind reality as you perceive it out the window. Myself I find it often overestimates rather than underestimates. But I have tinkered with that code quite a bit and am pretty satisfied with it right now. I may tweak it again later.

Hope this helps,

Ok, thanks.
