Ap+ burning more fuel

I did a flight with my friend (ymml-lfbo) he was in game for the whole flight meanwhile I used ap+,after securing that it’s gonna reach it with 1 hr left I left with ap+ after 5-6 hr I came back to climb it was perfect until 5-6 hrs later in America I came back to climb the ete was red I was 2 hr behind destination I tried everything but ended up diverting to kjfk,I didn’t know about this so tried and tried until I asked for help in discord one of the members said that ap+ uses more fuel so please fix this.

Device:iPad air 6th generation
Operating system:ios27

this fuel bug always happen everytime i load flight plan using simbrief. but if i try using the flight plan without simbrief and load fuel manually, it burn normal

Wow. I did a world tour in that thing and somehow they must have added external fuel tanks or something inflight because I came out with way more fuel then the thing can actually load

Infact I changed it to 100%fuel and 0 passenger and 0 cargo
