All I know is that if a pilot comes to me with 1000PIC hours logged in his logbook and he is applying for a captain job that requires 1000 hours of 135 PIC experience, and then I go and dig and find out that those 1000 hours logged were under the faa allowances of sole-manipulator, and he was a company designated SIC for all flights, he will get kicked out of my office so fast that I might actually forget about the experience of having my time wasted.
People will do what they want, it is up to management to distill quality from quantity for the best candidate.
This is where the topic of what's correct per the regulation ends, and the "can you?" discussion ends in favor of the "should you?" moral quandry.
It's best known as "where the rubber meets the road."
The legality of it bears no arguement, and has no room for discussion, and it's plainly spelled out. The practical application of the logbook, on the other hand, is as varied as the company to which one applies...and there's no way to predict who will view the flight experience as what. Accordingly, the breakdown of time comes in the form of the job application itself, not in the form of the logbook.
One cannot spend an entire career logging time tailored to one potential employer down the line; one should log in accordance with the regulation, and then break down one's time on the job application per the specific employer's needs.
As stated before, I've had some companies to which I've applied who considered my four engine piston time the same as a Cessna 172...they lumped all piston in together. Now there's a big difference between a large four engine bomber, which requires a type rating, and a little single engine Cessna...but they don't see it any differently. Am I going to lump them in together in my logbook? Of course not. But I will break them down on a job application according to the policies set by the employer.
Likewise, what one employer considers experience, another does not. One cannot fail by adhering to the regulation in one's log. After all, it's the regulation that prescribes what must go in the log, and what may and may not go in there. If one needs further clarification or division for a particular employer, then one should address that issue on one's resume, and in one's application forms.
