What is the deal with the turbine ticket? If you can keep a biggish piston engine healthy and efficient you should be able to grasp turbine operations in a couple of minutes. Push-button start just isn’t that hard.

These days a gas turbine endorsement is a thing. One less training course an operator needs to provide I guess

Still not getting it. Is a separate ticket required to operate an Pratt R-985? How about a Lycoming TIGO-541?

If you fly an aircraft with a turbine, have a look on your license. GTE will appear on their somewhere.

Don’t quote me on it, but I’m pretty sure it’s a course these days as part of doing a type rating on a turbine powered aeroplane.

It is a design feature in Part 61, the same as the retractable undercarriage, etc.

No separate ticket but if you read the fine print in Part 61 you will find a requirement to have completed sufficient training on the differences. Any operator valuing his equipment would demand that anyway. In the event of a claim because some dildo blew an engine to bits the insurer would want to know what training and experience the pilot had.
As for a separate gas turbine endorsement, for once this is not something CASA dreamed up. Many other ICAO States have required it since I was a boy, over 50 years ago. I recall the exam then being quite comprehensive. The most recent 'approved' GTE exam I saw was pretty basic stuff.
Are turbines more tricky to drive than supercharged radials or geared turbos ? Obviously not. But older turbines that still prevail in much of the GA fleet don't have the protections of the latest kit. The consequences of cooking one could exceed half a million bucks, as opposed to blowing a jug on your R985 - which could cost 10% of that.
Not too many operators would turn a 200 hour CPL loose on complex engines, which is why the OP would be spending unneccesary money at this stage.

:D:}

Or run it out of fuel.
