Hi…,
Welcome.
Gates info are in the FS’s scenery and not updated by our AIRAC’s.
Our Charts are provided by our real world provider and are not modified by Navigraph. Any gates info is not separately accessible by our Charts app.
We currently don’t update gates or taxiways but might do this in the future. But in the meanwhile most users use our Moving Maps function to correlate the data in the sim with the real world charts, at airports where the MSFS data is not accurate to the real world.

Cheers
