Good spot that man!
The range calc seems to only be using two engine's worth of fuel flow.
Obviously copied it in from the 1-11 & forgot to alter it.
From what I can tell it's always been like that, certainly pre dates this update anyway. Oops. :redface:
The estimated range is only a very simple calc for that moment in time from the current Fuel Flow, Fuel Quantity & Ground Speed.
That's the theory. Of course it will always be slightly on the high side if you only declare two thirds of the fuel flow.
I'll add it to the list of fixes.
Thanks for letting on bigred
