Under optimum visibility, how many minutes must the first rescue and firefighting vehicle reach the midpoint of the farthest runway?

• A. 3 Minutes
• B. 4 Minutes
• C. 2 Minutes
• D. 5 Minutes

Answer: (A)

The main idea is that rescuing and firefighting response times are set so the first unit can get to the farthest runway quickly enough to begin containment and rescue while conditions are best. Under optimum visibility, the target is to have the first rescue and firefighting vehicle reach the midpoint of the farthest runway within 3 minutes. This 3-minute standard reflects the balance between how fast a vehicle can realistically travel the distance from the station to the farthest runway and the need to start critical actions (evacuation, fire suppression, and safety coordination) as soon as possible. Shorter times, like 2 minutes, would be unlikely given typical distances; longer times, such as 4 or 5 minutes, are more aligned with reduced visibility or more challenging conditions, not optimum visibility. So the best answer is 3 minutes.
