What should a Pilot do if they encounter foreign military jets? Say you're flying an amateur-built plane just out over the waters of, say, Alaska. And then you encounter a fleet of maybe 5 foreign military jets directly above you, and then you get radio transmissions from the group in Russian. Well, what should a pilot do? The pilot doesn't understand Russian and is clearly not over any foreign airspace as the pilot is flying less than 20 miles south from the shores of Alaska, which shouldn't be somewhere that foreign military jets should be scaring pilots.
Would heading back to shore really be a good idea? The jets could potentially be hostile. So, what would be the wisest decision in this sort of scenario?
According to ICAO conventions the offical international language of aviation is English therefore it is unlikely that Russian fighter pilots will speak in Russian to a foreign pilot. If the pilot overlfying American waters, it's unlikely that Russian fighters are free to intercept planes in American airspace.
If such scenario happens, the pilot can report the situation to the ATC, then the situation will quickly escalate. If the private pilot is in American airspace and Russian fighters are not authorised, the private pilot should be safe following ATC directions and/or continue the route as planned. USAF will take care of the rest.
