According to National Fire Protection Association (NFPA) 402; Guide for Aircraft Rescue and Fire-Fighting Operations, which are the three minimum knowledge requirements about an airport?

The correct answer identifies the three minimum knowledge requirements that are essential for airport firefighters as outlined in the NFPA 402 guide. Understanding water supply locations is critical because firefighters need immediate access to water sources during an emergency. Knowledge of airport roads and bridges is also vital, as these are key routes for maneuvering fire apparatus and accessing incidents quickly. Familiarity with airport drainage systems is important as it helps firefighters manage potential hazards related to water flow and prevents further complications during an emergency response.

While the other choices contain some relevant elements, they do not encapsulate the comprehensive knowledge necessary for effective fire-fighting operations at an airport. For instance, airport service roads and lighting systems are helpful but do not encompass the holistic approach that understanding drainage systems provides, which can significantly impact operational safety and efficiency during a fire-fighting situation.
