This is not accurate. Remember, it is 5 hours of DUAL. The interviewers will assume that a low time pilot had the chance to fly a king air with an instructor. The questions will be more like "I see you have 5 hours of dual in a king-air. What did you do in the airplane and tell us what you learned from this experience." You will NOT be asked to describe the the type of engines, fuel system, etc in detail. Can you imagine a regional airline going out of their way to find a King Air pilot to then drill someone on the electrical system of a king-air with only 5 hours of dual?? That's absurd!

I was asked extensively about an aircraft I flew SIC in, with less than ten hours in it, at a 121 regional interview.

If you're logging time in anything, you need to have the knowledge of the aircraft to back it up.

You were SIC, not DUAL. There is a huge difference between the two. Acting as a crew-member and receiving instruction are entirely different.

To build on what Rick said, you can log whatever you want in your logbook. Its your logbook and not an FAA or airline logbook. Now, that being said what the FAA will accept as flight experience is outlined in 61.51, and SIC qualifications are outlined in 61.55. Consequently, the airlines or any other FAA certified operator will want to see 61.51 time.

SIC time in a single pilot King Air operated under Part 91 will just get you a pat on the back. Personally, I would subtract that time from your overall totals when you turn in the paperwork for airlines, 8710s etc. The only other thing that "SIC" time might be good for is insurance.

Absolutely. That shouldn't be an issue in the least, especially if the pilot you flew with noted training of some sort--e.g. "Intro to King Air 350 operation/ procedures." Any opportunity to fly a new plane is great.

Getting some knowledge of systems is always a good thing too. Friend of mine flew a Beech Premier (RA-390) in a Part 91 op. I was able to go along right seat on a few trips and fly some legs. He is an MEI and signed it off each time with a statement of some sort about the flight(s). Took it upon myself to spend a few hours learning the systems, not only to satisfy my own curiosity, but also that way I would know the major points of the plane if asked in an interview.

Just to be clear, you also passed a 135 SIC checkride in the King Air right? If so, and it is in your Ops Specs and other things that Rickair said logging it is totally legit.

Well lets just say that I know of one regional airline which does exactly that...your assigned interviewer will probably have some background in one or more of the same airplanes that you do. Coincidence? Not.

It's true that they would not expect someone who a few hours of dual to be an expert...but if you cross the line and log PIC or even SIC in 135, better know the plane.

Unless, of course, you enter something you shouldn't. Then it becomes "your logbook as evidence" to revoke all your certificates and ratings under 61.59.

Yep, my business records are mine too. I can enter whatever I want. Until the IRS audit, of course.

Your diary is 100% yours. Your logbook is an official record of time used to meet the requirements for certificate, ratings, operating privileges and currency.
