sir, i think you have a misguided view of LAEs
Having been an LAE myself for more than thirty years, I think I'm familiar with the breed.
As I'm not making a foreign flight then I don't need one
It has nothing to do with what sort of flight you're making or not making. It concerns what the particular Aircraft Radio Station is licensed for. If the aircraft has only VHF communications equipment and the AOC does not cover international flights - i.e. the aircraft and thus its radio station is restricted to domestic operations only - then you'd be correct.
The majority of the above posts are a pretty good indicator of the extent of the ignorance of radio operating procedures. Perhaps I've made my point?
