This might seem like a stupid question because I am not in the "industry" like some of you guys. Suppose you are flying a trip and you are so tired that you can barely keep your eyes open. You grab a drink at starbucks after a small nap in the crew lounge or whatever, what are your options as a pilot? Would you be penalized for calling your crew chief and saying you don't think it is safe for YOU to continue your duties? I mean what are the alternatives to flying under extreme fatigue?
Technically, if you DID fly in that situation, you'd be illegal. Any management will agree with you simply because if they didn't, they could be in serious trouble. The question comes in with how they handle it. Our policy here is, you call crew scheduling, tell them you're fatigued, and you're done for 10 hours. You need to fill out a report to document the event, which is no biggie. That covers the not flying part. NOW comes the shady part. You have to meet with base management to "discuss" why you called in fatigued, and they reduce your pay by 3.75. Yes, you lose out on money if the company schedules you in a fatiguing way or due to WX/MX or any other delay, you work so long you're too tired to continue. THIS is something I disagree with. You should fill out the report, and that should be the end of it.
So, in a realistic scenario, you've got an FO that makes $24/hr (we don't have any first year FOs here anymore, and I did say realistic). He's exhausted and staring at another 3-4 legs for the day. He really SHOULD call in fatigued, but he knows he's gonna have to do the carpet dance with the base manager, and he's gonna be out $90. Granted, after the meeting with the base manager, if they decide it was a valid fatigue call, he CAN get that back out of his sick bank. Once again, realistically, you're talking 1-2 MONTHS before he gets the money back. In the meantime, he's gotta figure out which bill he's gonna skip in order to NOT fly exhausted. I'm still waiting for the MEETING for a fatigue call I had back in December. So, I'm out $226 for that one that I haven't gotten back, yet. However, our management has declared our policy "non-intimidating" and "non-punitive." I disagree with them.
Now, other airlines have a VERY different policy. They play the "Call crew scheduling, tell them your fatigued and fill out a report" model. Then you're done.
Edit: Forgot to mention. If you're on reserve, they'll release you for 10 hours after your fatigue call. If you still have part of your reserve period after that 10 hours.....it's still there. I've called in fatigued before, got 10 hours and still had to do a HSV overnight before.....
