Call me an ignorant pig who doesn't take sufficient interest in other cultures
but that is the 2nd reason why I stick to international airports when going abroad (the 1st one is to avoid arrest).
Radio talk is a whole language, which like any other is highly context specific. You have to know more or less what is being said in order to understand it. This is why most PPL students go into instant brain overload when they are asked to fly the plane as well as do the radio.
Note also that non-international (i.e. domestic) French
airfield data is deliberately excluded from the notam data made available to ais.org.uk, so if you fly to one of those (obviously legal only on an internal flight) then you have to get notams from France (or perhaps more accurately from any notam source within Schengen). Whereas if you stick to international airports, ais.org.uk will do just fine.
