I’ve been using the FUEL TANK * QUANTITY to set the fuel loads in the sim from a client I’ve been working on for the last couple of years. Up until recently, I was ignorant to the fact that it doesn’t seem to be accurately setting the fuel loads.
In the Longitude, for example, I send a request to set both tanks to 50 gallons, but I only get 43.8 gallons.
Is there some sort of thing going on within the sim that’s trying to convert volume to weight but doing it poorly?
For what it’s worth, the Longitude is pretty consistently at 6.2 gallons off (+/- 0.3). The 172 is spot on. The Caravan is pretty close, only showing a +/- 0.01 difference at times.
Does it help to bump up the capacity?
