Don't be scared off by the Commanche. I've flown the twin version- it can be tricky to land, but it's just an airplane. Just trick your mind into thinking the interviewer is a student on their first lesson- or even better yet- one of your close friends or parents that wants to learn a bit about flying. Talk through everything that you do, be confident, and treat it just like any other airplane. Follow the checklists, fly the speeds, and you'll do fine. Remember- the interviewer is not expecting you to be an expert in the particular plane. Good luck.
