You need a Flight physical. Then you must take lesson at a FAA certified school. You need 20 hours with an instructor and at least 20 hours solo time in the airplane. Then you must pass a oral, then a written, and finally a practical exam.
You can go to a school designed in getting you your pilots license. I think you would
want to learn how to fly the plane before you went in for your license. So look into
pilot schools in your area and get started on your dream of becoming a pilot.
This is something you need to go to school for. There are many flying schools and instructors that can give you lessons, and give you the time you need to get your license. You need a certain amount of flying hours before you can get a license.
The easiest way to get one is to go through a pilot training program. Many of the smaller airports have a program that will cover the lessons and flying time.
The first thing that you should do is check your local area for a reputable flight school. If you would like to serve your country in addition to flight training, consider joining USAF Aux. (Civil Air Patrol). Top-notch training plus discounted rates add up tp a winner. God bless.
