Over Western Europe, is there any need for everybody to be on 121.5?
There are so many ground stations etc that the coverage is almost 100%.
surely if a D&D cell needs a relay, they will be able to contact a jet through the area centre.
Several times a day in the UK we need D&D to try and get contact with aircraft who are not listening out on the Area Centre frequencies that they should be. Other European ATC agencies have similar problems.
If you don't see a need for everyone to be monitoring 121.5 (when operationally possible), we'd better order more fighters for the inevitable interceptions
