Hi @Beechc23, unfortunately, this actually IS a core sim bug, and not just at EGKK. As Tezbedz says, it’s also true for other airports (not only in the UK) that the gates, and sometimes even the taxiways, in the sim don’t match those in real life.
To take the example of EGKK, consider these three charts:
Real life NATS AIP:
Navigraph Charts:
LittleNavMap (using MSFS database)
MSFS World Map:
NATS and Navigraph line up perfectly. From the screenshots I’ve seen of the addon Tezbedz mentioned, the add-on scenery is also true to real life, but vanilla MSFS (and as a result, LNM) is different.
