My faction has named me the pilot of two Y-wings. My instructor has told me to set one to NPC, take it to Ord Mantell and drop it off there. I set the second Y-wing to NPC and then flew the first Y-wing to Ord Mantell. When I got there I checked the Manage Piloted Ships page and the second Y-wing was still in the same place that it was before I left the previous planet. Do I need to be in the ship to set it to NPC? If this is answered in the Rules or Guide sections, could someone please provide a link?
