I have just updated from Microsoft Store to the latest version 1.0.2 but, apart from a slight improvement in the sounds, the problem remains.
I carried out a short flight of about 30 minutes. I attach screen shots of the fuel system and readings of fuel quantity.
You can see I started with 800lbs of fuel in aft and forward tanks cruised for about 30 mins checking fuel situation at 20mins and 30 mins.
You can see the fuel is being depleted from the aft tank at the rate of 600 pph while the fwd tank remains at 800lbs.
Since no one else seems to be reporting the problem, I imagine it is a problem with the Microsoft store version.
I hope you can see an answer to this!
Sorry but I inadvertently switched from NORM to Both on AFT when I intended to switch to both on FWD. But the reading at twenty minutes proves my point any way.
I intended to continue for another half hour with the fuel selector set to both on FWD tank to prove the point finally but was distracted. The 30 minute reading was however accurate before the switch.
