Our development team advises:
This is nothing we can work on, since these charts are not georeferenced by our supplier. They are not drawn to scale.
We recommend you use the enroute map and zoom in to the airport (as recommended here https://forum.navigraph.com/t/airfield-charts-to-assist-with-taxi-routes/11768/3), where the very detailed AMDB map can be used with moving maps. It shows all taxiways and parking positions.
Cheers
Ian
