Which statement about when the AUTO light illuminates is true?

• A. When all doors are armed, the AUTO light illuminates
• B. The MANUAL light illuminates when all doors are armed
• C. Both lights illuminate when doors are armed
• D. Neither light illuminates

Answer: (A)

Indicators on the door-arming panel show which mode is active. The AUTO indicator lights up when the system is in automatic mode and all passenger doors are armed, meaning slides will deploy automatically if a door is opened. The MANUAL indicator lights only when manual mode has been selected for one or more doors, not when every door is armed in AUTO. So the true statement is that the AUTO light illuminates when all doors are armed. The MANUAL light would not be on in that condition, and you wouldn’t expect both lights to be on or neither light to be on during normal all-doors-armed AUTO operation.
