During moderation, we try to set the range of the aircraft to be as close as possible to the real aircraft.
When we do not have detailed Range/Payload charts, we use the range value coming from the Wiki or any other valid source.
When users send us additional data with detailed charts, we use the point with max fuel and to the max payload possible. As AI flights are generally used with near max payload (more than 95% of the AI registered flights)
For instance, for the CRJ700 with this chart:
In this case, we obtain a range of about 2300 NM.
To facilitate aircraft add-on management and sharing, we group several add-ons under the same type.
For instance, the 8F has 5 addons in 3 different simulators:
Your particular add-on can have a very unrealistic fuel flow and allow much longer (or shorter) ranges when flying in the simulator
To propose changes on the aircraft database, we have an in-game feature to ask for specification changes:
