Thank you very much, Ronzie, for your help Since I it go to desmarcar, since this that you say to me, it has happened to me several times. In the flight of Barcelona LEBL to Palma de Mallorca LEPA, when 30 or 40 miles are absent to come to the airport, and to approximately 12000 feet, the RC remains mute. I can already do neither approach nor landing. I use FS9, RC, AS 6.5, Fspassengers and the AES of aerosoft, in addition to these airports also of Aerosoft. The same is, because it had this item chosenBest regardsRamón
