Hello Paul, I would like to know how to display the closest NAVAIDS that the aircraft is crossing either by reading a SQlite database or by comparing a flight plan loaded in the tracker. Always comparing the position of the aircraft to the beacon. Second point you gave me code to find the runway in service against the wind. But in the latest version of your dll you have also implemented AI traffic from IVAO. How to find either according to the Metar or according to the AI traffic
