Hello! I would love some help, please. 

Thanks,

This is accessed through "career" in the main menu. However, you need to progress through various ratings to unlock the different mission types.

Thanks, Martin. Do you have to start with certain aircraft?

Yes, at the beginning you're limited just a few types of aircraft -- Cessna 152, 172 and one other IIRC. This is based on your ratings -- for example, getting the high-performance endorsement unlocks the Bonanza and others in that category.

I see. I'll give that a try. what is IIRC?
