My experience with helping new turbine pilots is limited but the ones that I have helped have been capable pilots and just needed some help learning how to operate a turbine and learn to accommodate the spool time on landing. I have buddy boxed them and just sat with my finger on the switch the whole time. The only real difficult part of flying a turbine is landing. I would sit there with my finger on the switch thinking, "well if they mess up now there isn't much I could do about it."
