When should the motor igniter be armed?

The correct procedure dictates that the motor igniter should be armed after the rocket is positioned vertically on the launch pad, the deployment electronics are armed, and unnecessary personnel have moved to a safe distance. This sequence is crucial for ensuring safety during launch operations.

Arming the igniter at this stage ensures that the rocket is ready to be launched while minimizing the risk of accidental ignition. Positioning the rocket vertically is important for stability and ensuring proper flight dynamics once ignited. Arming the deployment electronics beforehand ensures that all recovery systems are prepared, which is essential for safely returning the rocket post-launch.

Moreover, ensuring that unnecessary personnel are at a safe distance is critical to maintaining safety on the launch site. This helps prevent injuries or accidents in the event of an unplanned ignition or launch malfunction. By following these steps, the risk associated with rocket launches is significantly reduced, allowing for safer and more controlled launching experiences.
