If you think you can handle an extra level of realism on Infinite Flight, come down to EGLL (London region) on the Free Flight-server for some quality verbal ATC using Zello!
EGLL Ground (121.90)
EGLL Tower (118.70)
Pilots should have at least some experience with verbal ATC (More than what is offered on IF).
Charts are also in use! Link to the airport diagram (taxiways):
Looking forward to seeing you there!
