Rule 109
The commencement, duration, location and extent of the no-fly zones must be appropriately notified to all concerned.
[Commentary]
A Belligerent Party establishing and enforcing a no-fly zone is under an obligation to publicize the details laid down in Rule 109 to “all concerned”, i.e. to civil aviation — own, enemy or neutral — if the zone will have an impact on such aviation. There is no obligation to inform enemy military aircraft (which are military objectives by nature). As to the means of communicating the details (e.g., by NOTAM), see paragraph 2 of the Commentary on Rule 107 (c).
