the stepping stone idea is no bueno in my book. More because you never know where the merry-go-round stops and where you'll end up. Ask the 10,000-20,000 hour FOs I saw after 9/11.
As is so often the case, posts by Polar for some reason make me feel like I need to inject my own opinion.
So, first and foremost, I agree with the others in this thread who have suggested that you only log PIC when you, in fact, sign for the aircraft. I hate it... because I have literally THOUSANDS of hours in airplanes that I am type-rated in... and that I was sole manipulator of the controls of... but in which I was SIC. Life would have been much, much easier over the last decade or so had I actually had a few thousand hours of PIC turbine in the 737. <shrug>
The folks that matter are looking for PIC time defined by signing for the airplane, and actually functioning in that command role.
Secondly, I agree with Polar with regard to the stepping stone idea. You know, it is very easy to be a Monday morning quarterback. I do it often (usually second guessing my own career choices). But as I'm so frequently reminded on this board, you make the best choices you can with the information you have at the time. So when I (for example) as a Jetstream 3100 first officer had the opportunity to apply for a job as a DC9 first officer... I took it. It was a pay raise, better airplane, better quality of life. Why wait for some unknown period of time to upgrade? And then fly for some arbitrary number of hours beyond upgrade to apply? If I was unqualified they would let me know by not hiring me. So I took the job as a DC9 first officer. When the opportunity arose to fly for a major airline rather than accept recall to an LCC... I took it. There was no PIC turbine qualification. The major paid more, had a better quality of life, and was (at the time) the "brass ring". So why not?
Now during the 4 or 5 years that all of this was taking place airlines were raising their qualifications very quietly in the background. Suddenly 1000 TPIC wasn't the exception... it was the rule. So as Polar indicated, after 9/11 all of us first officers (some with 10,000 to 20,000 TT) were suddenly in the unenviable position of finding ourselves no longer qualified to even APPLY for an equitable job.
Here's a bit of irony. I was not even qualified to RE-APPLY for a company that I had WORKED FOR just three years earlier?!?!?!!! Crazy huh?
I recognize that this makes me sound a bit disingenuous because I'm among the crowd here that attacks low time flight instructors who want to rush to the first CRJ seat they can find without "paying their dues" as a CFI or a freight dog. There's not much difference between the two scenarios.
I will tell you this -- (you being the folks who are considering skipping the stepping stones) -- the hardest part of my career from the pride and self-worth standpoint was sitting in class to become a turboprop first officer ... with 21 year old classmates ... after having been a major airline pilot for several years. Really made me feel like trash. So if you're going to skip stepping stones give it some good hard thought. That said, just because it didn't work out for me doesn't mean it won't for you... so don't look a gift horse in the mouth either. Winning the lottery is winning the lottery. Who cares how you got the money? You're still rich. Right?
And finally, it's not the end of the world if you gamble and lose. Every pilot who I was laid off with in 2002 is back flying again. Some went back to the major. Others are flying for some fantastic corporate flight departments, some went to other majors, some made careers at overseas airlines, freight airlines, fractionals, or even at the regionals. So nobody is going hungry.
So, I guess with some thought and a lot of rambling, my advice is... what have you got to lose? Roll the dice and see what fate has in store for you. You only live once.
