You're 19, so that would make you, at most a Sophomore (more likely a Frosh) in college, yes? Unless this "cadet" thing you speak of is something you do instead of school (I don't know about all this flying stuff). With that in mind, you may not have very many things to put on a resume, so you need to think carefully about what to include, and will probably want to restrict it to one page.
On that page, you will need to have your name, current address, permanant address (if different), and email address. These things should comprise the heading of your resume.
You will need a section for education. This section would include where you went to high school (though after college you would not put this), where you are going to college (if you are), your GPA (if it was impressive), the dates of attendance, and any honors you may have received. Also remember to put at least the state - if not the city and state - for any institution the employer would not certainly be familiar with.
You will need a section with your work experience. This can include full-time, part-time, seasonal, and school-related jobs. List your title, when you worked, and give a description of your duties. Try to tailor the descriptions to hit on the sorts of characteristics you think would be imortant to the job or program you are applying to. You don't necessarily need to put everything you have done on there, but you do want to make it look like you have
some experience doing something. As you get older, you will want to make sure there are not large gaps of missing time if someone does a chronology of your schooling and work.
You will need a section with your activities (in and out of school), and any non-scholastic accomplishments. Activities do not include, say, mountain biking unless you are a sponsored rider, often place highly in races (if you do, be sure to tell them), or you are somehow applying to ride bikes.
These sections do not need to go in this order (though it is standard to start with your educational background), and you could certainly have other sections if needed. Remember to make yourself sound good, but don't BS too much, and certainly don't lie.
In the end, there are a lot of places you can look, and a lot of people you can ask, but in the end you will figure most of it out when you sit down and try to write one.
Good luck!
