You may state, in the first contact, that you're "English speaking crew". This was working fine for a friend of mine while he was flying in Spain.
Well, if I make my initial call in English, I would think that this is already apparent. But in my experience, even if calls are initiated in English, and responded to in English, subsequent calls are often in French/Spanish. Due to controllers habit - especially with French/Spanish callsigns. This is quite natural and happens particularly when things are getting busy (again, naturally). This is also the time when the subsequent repeating is more disruptive.
What we need is a way of interrupting that habit with particular callsigns. A language marker on the flight plan, or the radar or something. But to interrupt habits, especially when busy, the marker needs to be conspicuous.
Have any controllers got any suggestions how this could be achieved?
