If the STROBE switch is in AUTO, the strobes will operate ____________

• A. When the main gear struts are retracted
• B. When the main gear struts are extended
• C. When the wing lights are on
• D. When the landing lights are retracted

Answer: (B)

In AUTO mode, the strobe system is tied to the position of the landing gear. The strobes are commanded ON when the main gear struts are extended (gear down) and will turn OFF when the gear is retracted. This ensures high-visibility strobes are active during taxi, approach, and landing phases when other traffic needs to see the aircraft, and not when the gear is up in flight. So the strobes operate when the main gear struts are extended. The state of wing lights or landing lights doesn’t drive the AUTO strobes, and they won’t flash simply because those lights are on.
