A320 VS1g question

[ok45]

Hi all, anyone know where to find actual V1sg for certain configuration in A320? A friend suggest as we know the Vref formula and that Vref is actually derived from VS1g , we can use it to calculate the VS1g.
If its so, will it be legal to use the calculated VS1g for operational use? (some CDL items requires us to know the number or else we'd be penalized in takeoff performance) Thanks

If you use the Airbus LPC toughbook then the takeoff performance page 'More details...' button should offer you this info, if I recall correctly. Can't help otherwise!

LPC

African Dude, thanks! but unfortunately we're not using LPC
I don't get it though, I mean if the number has an operational significance, why is it not being published? or maybe it's my ignorance that makes me couldn't find it

Pro lim 13 - VS1G charts are published here for our ops manual.

You need to look in:

FCOM -> Limitations -> 13 Speed Limitations

[Cough]

ES - that's the table for Vmca. Vs1g published later on in the same chapter...

Ha, would help if I read the question..
