Overfly or land in Turkey

ICAO may not care about state aircraft (as noted in the convention) but it allows states to request extra measures if they believe that they are needed (eg for safety reasons regarding civil aircraft). But this can happen only between neighbors that want to talk to each other…

Is it possible to overfly turkey ifr (bulgaria-cyprus) or will that be a problem?

Even though I know from our email communication, for the forum readers’ sake, stake if it is “ECAC member state” aircraft registration (i.e. European) or N’reg.
I am not sure if this affects the issue but I thought of it as a “for the record” thing.

Overflying the north part of Cyprus might be problematic, if your path crosses that area.

When overflying Turkey, put in RMK field “PRIVATE FLIGHT” (if that is the status of your flight), else the AIS will contact you to ask “what is the reason for this ECAC flight”.
