This is from our range duties document. An abbreviated version is printed on the back of our flight cards: Some of the items to consider for every flight: Are the launch guides secure? Is the motor retained securely? Is the motor certified and approved by the California Office of the State Fire Marshall? (It is the flyer’s responsibility to identify the motor and produce documentation for FSR examination.) Is the rocket construction sufficient to survive flight on the installed motor(s)? Is the rocket stable? (Ask the flyer about the CP location and how it was determined, and obtain the CG by balancing the rocket.) Will the rocket drag- or pressure-separate? Will the rocket recover safely? If electronics are used, how are they “safed” and “armed”, and what precautions have been taken to ensure that they function as planned? If motor ejection is used, is the delay appropriate for the flight?
