Far Cry 5 - Ace Killer Trophy Guide / Achievement Guide - Destroy 10 planes while driving any aerial vehicle (Campaign only) [Bronze]

Go to any Hangar or Boat Shop (green icons on map). Get a sea plane with a machine gun (Carmina, the Clusterduck, The Wild Goose). Carmina plane is unlocked automatically from Story Quest "Air Raid" in John's region (Quest Giver: Nick).

Now spawn another plane and destroy it with your own plane (press R2/RT to use the machine gun). You can stay parked for this, no need to lift off. Stay on the ground, don't fly. With this method the trophy is super easy. After destroying the plane, spawn a new one at the Hangar/Boat Shop and repeat a total of 10 times.
