mavrck,
Don't stress over the proving runs but down let your guard down either. And above all, don't be tempted to cut any corners... don't give them a reason to hang you... not even something as simple as sterile cockpit rules. The proving runs are not just about your ability to fly the airplane but also about your company's ability to manage it. Make sure everyone involved... pilots, dispatchers, DOM, maintenance control, whatever you have is available and in the loop. I say this because unless you have some good pull, you'll be doing some night flying which normally falls outside normal business hours. You will have a mechanical at some point, simulated or otherwise, and there is nothing worse than not being able to get a hold of your maintenance. BTW, if you have to use contract maintenance be sure they are on a drug program and your company has a copy of it before he starts to work on your airplane. Your DOM should know this but it will impress them if you are aware of the requirement. It seems to be a common "trick" to try and get one of the pilots out of their seat to test your knowledge of O2 requirements so know them cold. For what it's worth, I wouldn't send a pilot back for anything short of a fire... if for no other reason than the crew is new to the airplane and you don't need to be single pilot at this point. That's your call and you can refuse a request for someone to come back. Again, I wouldn't do anything outside the norm... even to the extent that I wouldn't take a visual into anything other than maybe my home airport. Use everything you have available to you. As was mentioned above, know your GOM/FOM, MEL procedures, and FARs. I would also take a look at the 8300/8400... it's nice to know where the FAA is coming from. Also as mentioned above, you'll have at least three inspectors involved but don't be surprised to see more. I had one with seven or inspectors onboard. Proving runs don't happen everyday so they sometimes use them for OJT. Anyway, I've found most inspectors to be good people... show them you know what you're doing, accept their advice (good or not) and you'll be fine. Good luck and have fun!
