All pilots who want to fly a two-seat “Light Sport Aircraft” will need to receive training from an FAA Certified Flight Instructor, and earn their FAA Sport Pilot Certificate.
If you want to own and operate a 2-seat powered parachute (such as the Infinity Commander), to either fly for pleasure pilot with your friends or family, or because you want to instruct or otherwise charge for your services, you will need to obtain a Sport Pilot license. Most single seat aircraft are considered "ultralight vehicles" and fall under the FAR Part 103 regulations, and do not require a license to operate.
In order to become a Sport Pilot, you must:
Obtaining your Sport Pilot license also requires taking a knowledge and practical test, along with proper logged/documented instruction and flight time from/with a Certified Flight Instructor.
The good news is that flying is a powered parachute is far simpler than flying most anything else in the world. The FAA requirements to become a licensed powered parachute pilot reflect that. Those wanting to become licensed in other aircraft have to spend more time gaining flying experience and have to do more to demonstrate proficiency in their respective aircraft than you will as a powered parachute sport pilot applicant.
There are a couple of ways to get the knowledge needed to become a sport pilot. New England Chute Flyers highly recommends home study courses, and you have several really good options to choose from. King Schools in particular offers award-winning video-based training that we highly recommend.
FLYING EXPERIENCE REQUIREMENTS
In order to become a sport pilot (assuming you don't already hold an FAA rating already) you will have to gain a certain amount of aeronautical experience working with a flight instructor. In the Federal Aviation Regulations, §61.313(g), the FAA requires that in order for you to be able to apply for a sport pilot license in powered parachutes you must:
This training needs to take place in an N-numbered powered parachute with a Certified Flight Instructor specializing in powered parachutes.
Your instructor should know when you are ready to take your check ride. When you are, he will make the proper endorsements in your log book and help you fill out your FAA Form 8710-11. At that point you will be ready and able to take your practical test and get your Sport Pilot license.
If you fly a "true ultralight," there is technically no training, and no medical currency requirement whatsoever. A Part 103 Ultralight is an aircraft that is a single seat, weighs less than 254 pounds, and has a gas tank capacity not exceeding 5 gallons, among other criteria. If you fly such a single seat powered parachute, and never plan to take a passenger, you simply need to be trained to proficiency.
Instruction to fly a single-seat powered parachute is virtually identical to that of a 2-seater. Just because there are no formal requirements from the FAA does not mean that learning to fly an ultralight is easier than that of its bigger brother, and students should budget accordingly for this training.
