The AUTO position of the NO SMOKING switch causes which of the following signs to illuminate when the landing gear is extended?

In the AUTO position, the NO SMOKING switch is designed to automatically activate certain cabin signs when the landing gear is extended. This includes the NO SMOKING sign, which is crucial for ensuring that passengers adhere to safety regulations regarding smoking during critical phases of flight.

In addition to the NO SMOKING sign, the EXIT sign is also illuminated. This serves to remind passengers of the nearest exits and promotes safety in case of an emergency during landing or taxiing when evacuations might be necessary. The combination of these two signs enhances the overall awareness of safety protocols within the cabin environment at a time when vigilance is paramount.

Understanding the logic behind the illumination of these specific signs reinforces the purpose of cabin safety measures and demonstrates how aircraft systems are integrated to ensure passenger safety during flight operations.
