INIT Page B "Not Allowed"

[studix2002]

1st flight in the A340-300 version 1.0.7 using the Hi Fly livery and I forgot to input the info on INIT page B before pushback (not sure if that makes a difference) anyway when I try to access page B on the Init A page by pressing left arrow or right arrow I get an FMS message "Not allowed"

ok, so i restarted the flight and the INIT B page works fine on initial setup before pushback...i still think it should be available after pushback

Thake this one up with airbus, INIT-B is always not allwed after engine start in all their family. Use Fuel Pred page

[IniSteve]

Kirkus is right. The Init-B is no longer avail after engine start. You'd then use the FUEL PRED page to check weights.
