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.
In order to understand high power rocketry enough to launch and successfully recover an L1 rocket, please make sure you have already read [[HPR Background Information]]. Level 1 Certification allows flyers to fly High Power Rockets with a total installed impulse up to 640 newton-seconds.

== NFPA 1127 and FAA 101 ==
'''''Note: Might be better to just give summaries of each relevant section and only post links to full documents. Someone please fix.'''''
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]. Here are the extremely relevant sections.
;§101.22 Definitions.
The following definitions apply to this subpart:
:(a) 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.
:(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.
;§101.23 General operating limitations.
:(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.
;§101.25 Operating limitations for Class 2-High Power Rockets and Class 3-Advanced High Power Rockets.
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:
::(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.
;§101.29 Information requirements.
:(a) Class 2—High-Power Rockets. When a Class 2—High-Power Rocket requires a certificate of waiver or authorization, the person planning the operation must provide the information below on each type of rocket to the FAA at least 45 days before the proposed operation. The FAA may request additional information if necessary to ensure the proposed operations can be safely conducted. The information shall include for each type of Class 2 rocket expected to be flown:
::(1) Estimated number of rockets,
::(2) Type of propulsion (liquid or solid), fuel(s) and oxidizer(s),
::(3) Description of the launcher(s) planned to be used, including any airborne platform(s),
::(4) Description of recovery system,
::(5) Highest altitude, above ground level, expected to be reached,
::(6) Launch site latitude, longitude, and elevation, and
::(7) Any additional safety procedures that will be followed.

=== Pre-flight Inspection ===
=== 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.

=== Certification Flight ===
=== Certification Flight ===
The rocket must be presented to the certifying member for inspection. If the rocket cannot be recovered, but can be inspected in place (power lines, tree, etc...) this is acceptable. The certifying member shall inspect the rocket for excessive damage. Excessive damage shall be considered damage to the point that if the flyer were handed another motor, the rocket could not be put on the pad and flown again safely. Damage caused by wind dragging will not cause a disqualification. If successful, the certifiers will sign the correct sheet to indicate that the certification attempt was successfully completed.

The certification sheets are returned to NAR or TRA Headquarters. No fees are required. The certification sheet must be returned by the certified individual or the event sponsors to NAR or TRA Headquarters to allow updating the NAR or TRA database. NAR sends an updated membership card showing the certification level upon receipt of the certification paperwork.

Tripoli hosts launches on the third Saturday of each month. Details, calendar, updates, and directions, as well as other pertinent information, can be found on their website here[http://www.tccrockets.com].
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.
