This table is suppose to make it easier. You need to know your Gross Lift Off Weight (GLOW) and your motor(s) specifications. Start from the top left of the table and keep going down and right until you meet all the requirements. The last cell will tell you what you have to do to fly your rocket.
This table is a combination of tables from the Model Rocketry handbook and the “Laws and Regulations for Transportation, Use and Storage of Fireworks in California”
