Sched? Long term carrier or short? What does the future there look like say 5-10 year down the road?
You realize that Neptune is an aerial firefighting operation, correct?
Schedule? You go out on a when dispatched, and come home when released. It could be anywhere from 90 days to 9 months. You get to come home when the season is over.
You won't know when the season begins, or when it ends until you're called-out, or when you're released.
Plan on 10-15 years for an upgrade. Don't plan on the P2's being around too many more years.
The large air tanker community is full. There are more experienced tanker pilots than there are aircraft. It's not to say you can't find a copilot job, but it may take a while.
Nobody cares if you have a degree, but an A&P will help make you competitive.
It's not a white collar job.
