I flew into KEYW yesterday and ATC had me taxi to parking taxi A, A5. When I looked at the Navigraph chart, it didn't have A5. There is taxi A1 - A4 going to the runway. But the taxiways going from Taxi A to the parking side was B1 - B12. So it should be B5 not A5. I looked at the scenery and you show A5... to parking. Does that need to be updated? And I have the latest Navigraph.
