The CRJ 700 escape path lasts for how long after charging?

• A. 2 hours
• B. 3 hours
• C. 4 hours
• D. 6 hours

Answer: (C)

Emergency lighting that guides you along the exit route is powered by rechargeable batteries. These batteries are charged while normal power is available, and once fully charged they provide illumination for a defined period if the primary power fails. For the CRJ 700, that endurance is four hours. This duration is set to ensure the escape path lighting can reliably illuminate the exits and route to safety for a complete evacuation even if the power stays out longer than a few minutes. The other durations don’t align with the CRJ 700’s specified emergency lighting endurance.
