What is the main reason for ensuring secure connections in a Level 2 rocket's wiring?

• A. To prevent arcing, shorts, and misfires; ensure robust, vibration-resistant connections.
• B. To improve the rocket's paint job.
• C. To increase the rocket's weight.
• D. To make wiring harder to replace.

Answer: (A)

A rocket’s flight environment is harsh for wiring: high vibration, accelerations, and temperature changes constantly threaten loose or poorly made connections. The main idea is reliability of the electrical system during ascent and ignition. When connections are secure and vibration-resistant, the firing circuits stay intact, preventing arcing to nearby conductors, shorts that can drain power or cause unintended ignition, and misfires caused by a connection opening or failing to complete a circuit. Proper crimps, strain relief, secure routing, and protective insulation keep the wiring from moving, wearing, or chafing under load, so inputs to igniters and deployment charges remain consistent and predictable.

Paint, extra weight, or making wiring harder to replace don’t address this reliability in flight. Painting doesn’t impact electrical performance, adding weight is counterproductive, and making wiring harder to service undermines safety margins and maintenance checks. The goal is a robust, dependable connection that can withstand the rocket’s dynamic environment.
