NAR HPR Launch Safety & Recovery Procedure 2 — Questions and Answers
Question 1: What is the minimum safe distance spectators must maintain from a high-power rocket launch pad during a Level 2 flight?
- 100 feet
- 200 feet (Correct answer)
- 500 feet
- 1000 feet
Correct answer: 200 feet
NAR safety codes require spectators to stand at least 200 feet from the launch pad for high-power flights.
Question 2: Under NAR rules, which condition requires an immediate 'hold' to be called during launch operations?
- Wind speed reaches 15 mph
- A spectator enters the safety perimeter (Correct answer)
- The rocket motor is being installed
- Clouds move overhead
Correct answer: A spectator enters the safety perimeter
Any unauthorized person entering the safety perimeter mandates an immediate launch hold to protect bystanders.
Question 3: When must the safety cap be removed from an igniter during a NAR-sanctioned high-power launch?
- When the rocket is placed on the pad
- After all personnel clear the range (Correct answer)
- During motor installation
- When the RSO inspects the rocket
Correct answer: After all personnel clear the range
The igniter shunt/safety cap must remain in place until everyone has cleared the range and the launch controller is armed.
Question 4: A rocket lands in a tree during recovery. What is the first action the flier should take?
- Climb the tree immediately to retrieve it
- Notify the LCO and wait for guidance (Correct answer)
- Cut the tree down if possible
- Leave the field and return the next day
Correct answer: Notify the LCO and wait for guidance
Notifying the LCO ensures safety protocols are followed and assistance can be coordinated for retrieval.
Question 5: What color flag or signal typically indicates a 'range clear' status, allowing personnel to retrieve rockets?
- Red flag lowered
- Green flag raised (Correct answer)
- White flag raised
- Yellow flag raised
Correct answer: Green flag raised
A green flag (or equivalent signal) raised by the LCO indicates the range is clear and recovery is permitted.
Question 6: Which of the following best describes a 'dual-deploy' recovery system used in high-power rocketry?
- Two parachutes that open simultaneously at apogee
- A drogue chute at apogee and a main chute at lower altitude (Correct answer)
- A parachute and a streamer used together at apogee
- Two separate rockets that deploy independently
Correct answer: A drogue chute at apogee and a main chute at lower altitude
Dual-deploy uses a small drogue at apogee to limit drift and a larger main chute deployed at low altitude for a soft landing.
Question 7: What is the purpose of a 'range safety officer' (RSO) at a NAR high-power launch?
- To collect launch fees from participants
- To inspect rockets and ensure compliance with safety codes before flight (Correct answer)
- To track rocket trajectories with radar
- To provide first aid to injured spectators
Correct answer: To inspect rockets and ensure compliance with safety codes before flight
The RSO inspects each rocket for structural integrity, motor compliance, and safety device functionality before authorizing flight.
