No worries B.Stuff,
I wouldn't get too hung up about the quantities when the cautions come on, we landed yesterday with 15 kg in the main with no cautions throughout. Normally at those levels I'd expect the fwd to come on when on approach/taxi. I guess the combination of wind, ac attitude and CoG position meant both pumps still pumping throughout. Both supply tanks still full.
Isn't it funny that when that balance ball spirit level thingy and nice little amber triangle on the PFD point to the right, the right hand supply tank reads a bit low, regardless of main contents
