PSA Airlines Canadair Regional Jet Systems (PSA-CRJ) Practice Exam

How long can emergency lights provide lighting?

1. 5 minutes

2. 10 minutes

3. 15 minutes

4. 20 minutes

The correct answer is: 10 minutes

Emergency lights on the PSA Airlines Canadair Regional Jet are designed to automatically activate in the event of a power failure or emergency situation, providing essential illumination to assist passengers and crew in evacuating the aircraft safely. The correct duration for which these emergency lights can provide adequate lighting is typically up to 10 minutes. This timeframe ensures that there is enough visibility to navigate darkened environments after a sudden loss of cabin lighting, thereby enhancing safety during critical moments. The system is engineered to strike a balance between providing sufficient emergency illumination while conserving battery power, as extended lighting could potentially compromise the power available for other emergency systems. Understanding this operational design is crucial for crew training and emergency preparedness, as it informs evacuation protocols and ensures that crew can guide passengers effectively during an emergency.
