Just bought a nav box,is it possible to pick any military aircraft at all.
Many will appear in the aircraft list, but only a few will ever appear on the map. Only "civilian" type aircraft used by the military will appear on the map.
Are all the military aiicrafts been listed ? what about military classified aircrafts ? I don't think they will list here :p
As a matter of fact some of the highest classified USAF aircraft do have full ADS-B and do appear on the map - the Boeing E-6B Mercury for example.
However, if you wish to track military and civil aircraft equipped with just mode-S there is only one product that will allow you to do that - PlanePlotter with multilateration from COAA.
