In order to understand high power rocketry enough to launch and successfully recover an L1 rocket, you must read, live, and understand the following information. Level 1 Certification allows flyers to fly High Power Rockets with a total installed impulse up to 640 newton-seconds.

NASA's online [https://spaceflightsystems.grc.nasa.gov/education/rocket/shortr.html Beginner's Guide To Rockets] will get you started on many of the basic principles governing rocketry. If you manage to make your way through all of these, you will understand the vernacular often used in rocketry.

The National Fire Protection Association has multiple documents spanning different types of rocketry. Section 1122 governs model rockets and 1127 governs high powered rockets. We are most interested in 1127.

[http://unh.edu/rocketcats/NFPA-1127.pdf NFPA 1127] sets the rules and regulations for high power rocketry, including the motor classification system, rules for Range Safety Officers, and guidelines for the safe construction, use, and storage of rocket materials. Critically, it also includes the formal definition of High Power Rocketry, and it is this definition that is referenced in ITAR.

The Federal Aviation Administration Regulations also has a relevant section to the high powered rocketry community. [http://www.ecfr.gov/cgi-bin/text-idx?rgn=div5&node=14:2.0.1.3.15#sp14.2.101.c FAA 101 Subpart C, Amateur Rockets], states:

=== Pre-flight Inspection ===
The model will be subjected to a safety inspection prior to flight. The safety inspection form is on the back of the NAR High Power Certification Application. During the safety inspection the modeler will be expected to provide oral answers to technical questions related to the safety and construction of his model. The questions may include (but not limited to) identification of the model’s center of gravity and center of pressure, methods used to determine model stability, and interpretation of the rocket motor’s designation. The certification team will initial (or check) the blocks indicating that model safety, motor certification, and the existence of a FAA waiver (if required) in effect were verified prior to flight.

Be aware that Tripoli has slightly different policies and forms from NAR, as well as requiring a separate Tripoli membership in order to launch. However, certification levels from either are accepted at the other, i.e. if you are certified L1 through Tripoli, you can get your L2 certification at NAR, as long as you are a registered member of both.

== Prepping Your Motor ==
  −
 
  −
If using a single use motor or Disposable Motor System, make sure to check that the delay on the ejection charge is correct using a simulation software (i.e. OpenRocket). If needed adjust the length of the delay grain. Then place the correct quantity of ejection propellant in the correct location. Cap it.

  −
=== Motors ===
  −
 
  −
Is the motor certified, what is the motor type and average thrust? Is the delay time is approximate for rocket?
  −
 
  −
Will the rocket penetrate cloud cover?
  −
 
  −
Does your rocket motor have the ejection charge installed?
  −
 
  −
Is sufficient wadding/Kevlar installed?
  −

What kind of motor retention system is installed?
  −
 
  −
What prevents the motor from flying-through the rocket?
  −
 
  −

  −
 
  −

  −
 
  −
Launch lugs and/or rail guides properly installed, positioned, and aligned?

  −
== Launch Pad Procedure ==
  −
 
  −
The rocket should slide freely on the rail. The pad angle should be within 20 degrees of the vertical axis (normal to the surface of the earth). Flight critical electronics (if there are any) should be armed before putting in igniters. Any radio control equipment should also be nominally operating before arming the igniters.
  −
 
  −
=== How to install an igniter ===
  −
 
  −
Place in the nozzle of rocket, and tape the igniter to the rocket so it does not slide out. '''Make sure not to short the leads of the igniters. '''

Make sure to wash off all the metal components of your rocket so they do not corrode from left over motor fuel.
