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

Which of the following is true about the landing and taxi light lenses?

1. Both are clear

2. Landing lights are diffused, Taxi lights are clear

3. Both are diffused

4. Landing lights are clear, Taxi lights are diffused

The correct answer is: Landing lights are clear, Taxi lights are diffused

The correct answer states that landing lights are clear while taxi lights are diffused. This distinction is important for operational purposes. Landing lights are designed to provide maximum illumination during landing approaches, and having a clear lens allows for a brighter and more focused beam of light. This is crucial for pilots to see the runway and surrounding environment clearly in low visibility conditions during approach and landing phases. On the other hand, taxi lights are intended to provide illumination for ground movements. A diffused lens helps to provide a wider spread of light rather than a focused beam. This spread is useful for illuminating the taxiways and surrounding areas without creating excessive glare that could impair visibility, particularly for other aircraft and ground personnel. Each type of light serves a specific function that is essential for safe operations, particularly during critical phases of flight such as landing and taxiing.
