Hello,I've experienced this too, lately, and I would like to ask if there is a solution or not. In my case though, it doesnt happen during reloading a saved flight or loading saved FMC route, but when i fly from FAJS, from clean cold&dark cocpit, I load the FMC from the scratch and as soon as I type FAJS into departure arpt., FMC says "ANVOX ERROR". When i flew to FAJS, it displayed also this error, however it had no influence whatsoever on the flight performance or anything else, but as soon as the FAJS was the departure airport, FMC displayed this error, and there were NO runways for FAJS in the FMC. So this is not random individual error, if more people experience it and moreover, it doesnt seem to be linked to saved flights. Does anyone know what is causing this and how to get rid of this error?
