Truboprop #3 - startup logic (even the most basic behavior on startup)

Following up on the closed bug threads:

I would like to mention and put up for voting the issue of startup logic for turboprop engines.

Currently, the process of startup does not reflect the correct indications during startup and is not limited nor influenced by parameters that should be considered in the real world.

For clarification, what is supposed to happen in startup that’s not in the sim today?

To the untrained eye, it looks okay on the Caravan, but I’ve never flown a turboprop IRL so I don’t know what I’m supposed to be looking for other than the basic theoretical elements.
