At McCarran Intl (LAS), what is the minimum number of aircraft rescue and firefighting vehicles required under 14 CFR Part 139?

The minimum number of aircraft rescue and firefighting vehicles required at McCarran International Airport (LAS) under 14 CFR Part 139 is determined based on the airport's classification, which considers factors such as the length of the runway and the types of operations conducted. Specifically, for airports with higher classifications that support larger aircraft operations or have longer runways, the requirement increases accordingly.

In this case, McCarran International Airport, being a significant airport with commercial operations, mandates at least three aircraft rescue and firefighting vehicles. This ensures that there is sufficient capability to respond to emergencies effectively, maintaining safety for both passengers and air traffic. The regulations are structured to provide a robust safety net, guaranteeing readiness for various situations that could arise during takeoff, landing, or ground operations.

Therefore, having three vehicles not only meets regulatory compliance but also enhances the airport's emergency response capacity, reflecting the seriousness with which aviation safety is treated.
