What
@cfam said. PFI is a very small program with a very iffy future, and I wouldn’t get too invested in it for your own career plans. It’s one of the various small scale deals the Navy’s tinkered around with over the last 10-20 years trying to establish some kind of limited “permanent pilot” track that lets some folks stay in the cockpit and retain their experience in the Fleet without worrying about “up or out.” It’s more likely to go the way of the Flying Warrants.
If you fly Navy, assume you’re going to have to do a traditional career track. If you want to just stay in the cockpit, look at the Army.
