Есть у меня коробочная версия F/A-18 от Jane's с мануалом. В мануале написан жаргон NATOвских летчиков. Буду писать по английски:

Sunrise - Informative call that radar functions are available. Opposite of Midnight.

Midnight - Information call advising that C2 radar functions are no longer available.

HotDog - Informative/directive call that an aircraft is approaching or is at a specified standoff distance from the sovereign airspace of a nation (as defined by national boundaries or territorial sea and airspace).
