What is the minimum number of ARFF vehicles needed based on aircraft length and daily departures?

• A. Aircraft size and fuel type
• B. Aircraft weight and passenger capacity
• C. Aircraft length and daily departures
• D. Aircraft model and crew size

Answer: (C)

The minimum number of Aircraft Rescue and Firefighting (ARFF) vehicles required is determined by evaluating aircraft length and the number of daily departures. This approach is pivotal because the length of an aircraft correlates with the potential severity of a fire or emergency incident; larger aircraft require more extensive firefighting resources. Daily departures also factor in because a higher frequency of takeoffs and landings increases the likelihood of incidents occurring, necessitating adequate ARFF coverage during peak operational hours.

Using the aircraft length ensures that the emergency response capability corresponds with the size of the aircraft that frequent the airport, while accounting for daily departures allows fire services to appropriately prepare for multiple aircraft in operation. This combination supports effective risk management and resource allocation, ensuring safety standards and regulatory compliance are upheld.

In contrast, considerations like aircraft size and fuel type, weight and passenger capacity, or model and crew size may not directly influence the minimum ARFF vehicle requirement as effectively as the length and operational frequency.
