Can someone help me break this down. I have a April class date and I'm still trying to wrap my head around how this works. From what I've read, I believe if I take a CA slot during indoc I would start flying as an FO. At 350 hours, I start recieveing captain pay and at 500 hours I would be eligible for upgrade. Please correct me if I'm wrong. I'd also like to know at 500 hours is upgrading mandatory or do I still have a choice?
