FAA Regulations
In the latest rules, the FAA has defined three classes of amateur rockets in regards to our hobby. The Class 1 and Class 2 categories are the most relevant to NAR members and will be the focus of this article. You can read the complete regulations for additional information, including details on the Class 3 rocket category.
Class 1 Model Rockets
Class 1 rockets include what used to be known as model and large model rockets. They are defined at 14 CFR 101.22 (a) of the regulations and are listed as:
Class 1- Model Rocket means an amateur rocket that:
(1) Uses no more than 125 grams (4.4 ounces) of propellant;
(2) Uses a slow-burning propellant;
(3) Is made of paper, wood, or breakable plastic;
(4) Contains no substantial metal parts; and
(5) Weighs no more than 1,500 grams (53 ounces), including the propellant.
Launching large model rockets used to require providing prior notification to the FAA. Now, no such notification is required. So long as the general operating limitations at 14 CFR 101.23 as listed below are followed, they can be launched freely.
(a) You must operate an amateur rocket in such a manner that it:
(1) Is launched on a suborbital trajectory;
(2) When launched, must not cross into the territory of a foreign country unless an agreement is in place between the United States and the country of concern;
(3) Is unmanned; and
(4) Does not create a hazard to persons, property, or other aircraft.
(b) The FAA may specify additional operating limitations necessary to ensure that air traffic is not adversely affected, and public safety is not jeopardized.
Class 2 High Power Rockets
The Class 2 rocket category covers high power rockets and is defined at 14 CFR 101.22 (b) and is listed as:
Class 2 - High-Power Rocket means an amateur rocket other than a model rocket that is propelled by a motor or motors having a combined total impulse of 40,960 Newton-seconds (9,208 pound-seconds) or less.
While the older rules prohibited flying unmanned rockets into controlled airspace, the latest rules do not. The newer rules do however, require prior authorization before launching. This is part of the operating limitations for Class 2 High Power Rockets found at 14 CFR 101.25 and stating:
When operating Class 2-High Power Rockets or Class 3-Advanced High Power Rockets, you must comply with the General Operating Limitations of §101.23. In addition, you must not operate Class 2-High Power Rockets or Class 3-Advanced High Power Rockets—
(a) At any altitude where clouds or obscuring phenomena of more than five tenths coverage prevails;
(b) At any altitude where the horizontal visibility is less than five miles;
(c) Into any cloud;
(d) Between sunset and sunrise without prior authorization from the FAA;
(e) Within 9.26 kilometers (5 nautical miles) of any airport boundary without prior authorization from the FAA;
(f) In controlled airspace without prior authorization from the FAA;
(g) Unless you observe the greater of the following separation distances from any person or property that is not associated with the operations applies:
(1) Not less than one quarter the maximum expected altitude;
(2) 457 meters (1,500 ft.);
(h) Unless a person at least eighteen years old is present, is charged with ensuring the safety of the operation, and has final approval authority for initiating high-power rocket flight; and
(i) Unless reasonable precautions are provided to report and control a fire caused by rocket activities.
Prior authorization from the FAA, as mentioned in 14 CFR 101.25, items (d), (e), and (f), pertain to having an approved Certificate of Waiver or Authorization (COA) issued by the FAA. To get approval to make Class 2 rocket flights at a certain location, you must first apply for the COA using FAA Form 7711-2. You can find help with filling out this form at the link located at the end of this article. Once the application and other required information has been received, the FAA will conduct an airspace review to determine the compatibility of launching Class 2 rockets with other uses within the designated airspace.
