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

How long can the Taxi lights operate when the aircraft is stationary?

1. 5 minutes

2. 10 minutes

3. 15 minutes

4. Unlimited time

The correct answer is: 10 minutes

The taxi lights on a Canadair Regional Jet, like those on many aircraft, are designed to enhance visibility while the aircraft is moving on the ground. When the aircraft is stationary, the operation of the taxi lights is limited to prevent overheating and excessive battery drain. In this case, the correct duration for which the taxi lights can operate when the aircraft is stationary is 10 minutes. This limitation allows pilots to use the lights for brief periods without risking potential damage or impact on the aircraft's electrical systems. Maintaining a 10-minute operational window helps ensure the longevity and reliability of the lighting systems while providing the necessary visual cues in situations where the aircraft is not in motion.
