certification, each allowing the user to fly successively larger motors. In the US (TRA and NAR): Level 1: H, I Level 2: J, K, L Level 3: M, N, O and beyond Note: In Canada, the Canadian Association of Rocketry has an additional step to Level 4, which is equivalent to the US Level 3. Level 1 is H motor, Level 2 is I motor and CAR Level 3 and 4 is the same as U.S. Level 2 and 3, respectively. Due to a change by the Board of Directors upon recommendation from the RSO Committee, all hybrids are considered High Power. In order to gain certification an individual needs to demonstrate their ability to fly a rocket within the given power range of the level they are seeking successfully. For example, if an individual desires to gain a Level 1 certification they must successfully fly an H-I motor in an appropriately sized rocket and retrieve it successfully in a condition suitable to launch it again safely. This is also true for Level 2 and 3 certification with the added requirements that, for Level 2 a written test be successfully passed and for Level 3 the build be documented and overseen by two designated technical authorities called TAPs (Technical Advisory Panel) who are themselves Level 3 certified and notably proficient at rocketry. The level 3 technical authorities are authorized by the respective Tripoli or NAR national organizations. These requirements vary slightly between NAR and Tripoli, but are very close in both organizations. The above rocket motor impulse levels would all be classified as Class 2 rockets per the US Federal Code of Federal Regulations CFR Title 14 Aeronautics and Space, Part 101, Subpart C, 101.22 Definitions: “(b) 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. (c) Class 3—Advanced High-Power Rocket means an amateur rocket other than a model rocket or high-power rocket". Tripoli Rocketry Association maintains a Class 3 review committee who voluntarily (not required by the FAA) review rockets with altitudes expecting to reach or exceed 50,000 feet and as a pre-check for rocket projects that will be submitted to the FAA as a class 3 project. The Class 3 review committee performs the following functions: Performing a 3-sigma, 6-degree of freedom dispersion analysis on
