It is penalty of 180 percent which comes on top of the normal burn.
Assuming normal FRF 1250 and ALTN fuel of 1750,
3 + 3 x 1.8 = 8.4 T.
If that was for G HYD LO
PR with doors hanging, there's another +15% IIRC.
True, thats correct if you assume QRH FPF factors. This is conservative and of course its the safest.
Real consumption is much less, close to x2.1 (ref Bomb on board QRH)
Plus, with flysmart in-flight calculation you can have more realistic consumption calculation according to your selection in the EFB (Select NSC)
After some emails between my company and airbus to clarify, airbus replied that flysmart is more accurate and approved app to calculate such computations in-flight
So thats good news
