I just spoke with an OSP pilot about three weeks ago at my FBO. In the central Ohio area, they are based out of KOSU. He informed me that any applicants for pilots with OSP must already be troopers assigned to patrol duties (car/office/etc). They are also currently hiring based on seniority within the department as opposed to pre-existing pilot credentials as they did in the past. From my discussion with the pilot, you could probably expect to be in the car for at least a few years AFTER completing academy before moving into the C182s. If you make it that far, though, you can rack up some pretty substantial TT and make weekly stops at JP's for BBQ :-)
