NAR HPR Launch Procedures & Checklists 2

Question 1

During a pre-launch checklist, when should the igniter be installed in the motor?

Accepted Answer

After the rocket is on the pad and all personnel are at safe distance

Answer

The igniter should be installed after the rocket is on the launch pad and all non-essential personnel have cleared the safety radius.

Question 2

What does 'range safety' refer to in the context of a high-power rocketry launch?

Accepted Answer

Procedures and protocols ensuring all launches are conducted safely within established boundaries

Answer

Range safety encompasses all procedures, rules, and protocols that ensure launches occur safely within designated boundaries and protect all participants.

Question 3

Which action should be taken if a misfire occurs and the motor fails to ignite after a launch attempt?

Accepted Answer

Wait the required hang-fire period (typically 60 seconds) before approaching

Answer

NAR safety codes require waiting a minimum hang-fire period (commonly 60 seconds) before approaching a misfired rocket to allow any delayed ignition to occur safely.

Question 4

What is the purpose of the 'arm/safe' switch on a high-power launch controller?

Accepted Answer

It prevents accidental ignition by requiring a deliberate arming action before firing

Answer

The arm/safe switch is a safety interlock that requires a deliberate two-step action (arm then fire) to prevent accidental ignition.

Accepted Answer

The range is clear and all personnel are beyond the minimum safe distance

Answer

The LCO must confirm the range is clear and all personnel are beyond the minimum safe distance before initiating any launch countdown.
