I think it would help pilots who are departing or arriving at a airport that not currently active by ATC to have the ATIS coms set to all airports.
I know that there’s a weather report when you open the flight planner but it would help if the Atis was active regardless if ATC is currently active at the airport.
It would give IF more realism because of the automated weather system at non controlled airports like at Class Echo airports and same concept for airports that are usually active like EGLL and KLAX.
