Just wondering...recently updated Fsnav to airac 606 from Navdata site and noticed Radar Contact 3x on the list. Had a look around the Data folder in Rcv4 and came across an entry with airac 0408. What's to go here? Are we supposed to update these as they come along or doesn't Rcv4 use them?

no, i get my data from your scenery files via makerwys, and from the flight plans you load.no need for the airac datajd

>... and>from the flight plans you load.>>no need for the airac data>>jdHi, jd,Airports - OK but does it mean that there is no need for waypoints data provided by AIRAC either?Regards,Rustam

nope, i get that information from the .plnjd

Waypoints data comes from the flightplan. Navaid frequencies at the airport come from the database build.RC does not autotune nav receivers so the coordinates in the .pln file is all it needs.Waypoint coordinates come from your flight planner. You would update your flight planner if it accepts AIRAC updates.
