What is the one procedure for relighting the burner while in flight?

• A. Open another tank valve, open the regulator or blast valve, and light main jets with reduced flow
• B. Shut off all gas and restart engine
• C. Replace the burner with a spare in flight
• D. Light the main jets without adjusting flow

Answer: (A)

Relighting the burner in flight relies on keeping a steady fuel supply while controlling the flame as you re‑ignite. The safe method is to open another tank valve to ensure ample propane, then open the regulator or blast valve to meter the gas, and light the main jets with reduced flow. This sequence gives you the fuel you need, prevents a dangerous, oversized flare or backfire by limiting the initial flame, and lets you gradually bring the burner back up to the desired heat. Once lit, you can increase the flow to reach the target heat safely. Why the other options don’t fit: there isn’t a situation where you replace the burner in flight, and there’s no engine to restart in a hot air balloon. Shutting off all gas would extinguish the flame and prevent relighting, while lighting the jets at full flow without prior adjustment can cause an uncontrollable flare and risk damage or injury.
