Multi Engine Piston vs Multi Engine Turbine
 

First, I KNOW that twin turbine PIC time is better than twin piston PIC time. My question really is, is starting out in a multi engine piston airplane as PIC the normal when starting at a 135 operator in lieu of a multi engine turbine airplane such as the 99? I've gotten an offer from a company that operates both types of equipment but they'd rather have me start in their twin piston aircraft instead of their twin turbine aircraft (BE99). I already have a lot of twin turbine time as SIC and they acknowledged that and think it's great but they'd still rather have me start in the piston. Is this the normal right now for the current industry for pilots at 135 IFR PIC mins to start in a multi engine piston or is a multi engine turbine airplane more than possible?

Thank you in advance to anyone who replies.

If you don’t want to fly their twin piston don’t accept the job offer. Look for another job where you can start in a twin turbine.

If you do want to work for them take what they offer, get some experience and then flow to the twin turbine. At the rate guys are leaving for the airlines you’ll probably be in the turbine in 6 months.

As far as what’s normal. Whatever the employer wants is the norm. That’s new guys starting at the bottom and work their way up. You decide if that’s acceptable to you.

Twin pistons, in general, are cheaper than twin turbines. Despite the pilot shortage operators like to observe a newhire in a piston for a while before letting them loose on the expensive equipment. Most screwups managing a piston engine cost about 10% of one good screwup with a turbine. I know a guy that accidentally added fuel to two turbines as they were spooling down. Expensive. He was a 500 hour pilot that had bought 500 hundred hours of SIC time with Ameriflight in the early nineties. Your future employer wants to figure out if you’re that guy before it’s going to cost him a small fortune.

How much is a "lot of twin turbine time as SIC?"

Twin turbine as SIC.
What makes you think you can go to a different company and be PIC?
No offense but maybe you weren’t upgrade material at your previous employer. Who is to know?
That’s why you’re starting on a piston.
If you don’t break anything you’ll move on to the turbine.

The original poster didn't give much detail. It may not have been inability to upgrade, but it may have been logged in a ride-a-long situation. Regardless, without experience performing the duties of PIC (or the responsibilities), and with very little or no PIC multi experience, it's reasonable to put someone in a piston twin before moving them to a turbine twin, for insurance if for no other reason. It would be expected at most places, or at least, it used to be that way.

Pretty much all of this. Why not look into the appropriate sub thread for the company in question to see about similar upgrade times if you're that worried.

If you must know, I was slated to upgrade. The reason I’m not upgrading is because the company I work for requires an ATP and I don’t meet the age requirements.

I have over 900 hours of twin turbine SIC (this was obtained as legal time) and 110 hours multi PIC.

Which you knew when you got hired.
So now you’ve got an itch and you want to jump.
But you got stepped on your wiener because they didn’t roll out the red carpet to the turbine and instead they pointed to a lowly piston.
Depending how long you have to wait you may be better off at your present employer and upgrade when you get your ATP.
Or stop being entitled and build PIC Piston ME time.
