B. Water supply locations, airport roads and bridges, and airport drainage systems
C. Terminal layouts, baggage handling areas, and parking structures
D. Fuel storage capacities, runway lengths, and control tower frequencies
Answer: B
Rationale: NFPA 402 specifically requires ARFF personnel to know water supply locations, airport
roads and bridges, and airport drainage systems as foundational knowledge for effective response
and positioning -1-5.
2. Parallel runways are distinguished by:
A. Numbers only
B. Letters
C. Colored markings
D. Light signals
Answer: B
Rationale: Parallel runways are distinguished by letters (L for left, R for right, C for center) added to
the runway number to differentiate them for approaching pilots -1-12.
3. Which color of lights is used to outline the edges of runways and are spaced approximately 200
feet apart?
A. Blue
B. Green
C. White
D. Yellow
Answer: C
Rationale: White lights outline runway edges and are spaced approximately 200 feet apart,
providing visual guidance to pilots during approach and landing -5.
4. Control tower operators direct vehicular traffic on taxiways and runways by means of:
A. Hand signals only
B. Light signals and radio communications
,C. Written instructions
D. Flags and markers
Answer: B
Rationale: Control tower personnel use both light signals and two-way radio communications to
direct vehicular traffic on taxiways and runways -5-13.
5. What is the Rapid Response Area (RRA)?
A. The area surrounding the terminal building
B. The area surrounding the runway 500 feet to each side of centerline and extending 1650 feet
from runway ends
C. The fuel storage facility perimeter
D. The aircraft parking apron
Answer: B
Rationale: The RRA surrounds the runway 500 feet to each side of the centerline and extends 1650
feet beyond the ends of the runway, representing the area where ARFF response is most critical -16.
6. What does the runway number indicate?
A. The number of people required for rescue
B. The runway length in thousands of feet
C. The nearest compass bearing rounded to the nearest ten degrees
D. The chronological order of runway construction
Answer: C
Rationale: Runways are numbered based on the nearest compass bearing rounded to the nearest
ten degrees (e.g., Runway 27 is oriented approximately 270 degrees magnetic) -12.
7. Which areas on an airfield are used for luggage handling, aircraft refueling, and personnel
movement?
A. Runways
B. Taxiways
C. Ramps
D. Service roads
Answer: C
Rationale: Ramps are the airfield areas designated for luggage handling, aircraft refueling, and
personnel operations -8-20.
8. During periods of elevated threat levels, emergency vehicles should not be parked closer than
how many feet apart when parking near or in front of airport terminals?
A. 5 feet
B. 10 feet
,C. 25 feet
D. 50 feet
Answer: B
Rationale: During elevated threat levels, vehicles must be parked at least 10 feet apart to minimize
damage from potential explosive devices -16.
9. What is the Critical Rescue and Firefighting Access Area (CRFFAA)?
A. The area immediately surrounding the terminal
B. The area surrounding the runway 500 feet to each side and extending 3300 feet beyond runway
ends
C. The fuel farm perimeter
D. The aircraft maintenance hangar area
Answer: B
Rationale: The CRFFAA surrounds the runway 500 feet to each side of centerline and extends 3300
feet beyond the ends of the runway, representing the area requiring the most rapid ARFF
intervention -16.
10. What are frangible gates designed to do?
A. Prevent unauthorized access permanently
B. Break away when struck by ARFF apparatus responding to an off-airfield incident
C. Serve as passenger boarding gates
D. Control aircraft taxiing
Answer: B
Rationale: Frangible gates are designed to break away when struck by an ARFF apparatus, allowing
rapid access to off-airfield emergency incidents without delay -16.
11. Which of the following should never be blocked on an airfield?
A. Service roads
B. Instrument Landing Systems (ILS)
C. Parking areas
D. Terminal entrances
Answer: B
Rationale: Instrument Landing Systems (ILS) provide critical navigation data to aircraft and should
never be blocked, as doing so could compromise aircraft safety during inclement weather
operations -16.
12. According to NFPA 403, airport categories for a given aircraft are based on:
A. Wingspan
B. Overall length
, C. Passenger capacity
D. Maximum takeoff weight
Answer: B
Rationale: NFPA 403 categorizes airports based on the overall length of aircraft that regularly use
the facility, which determines the required ARFF capabilities -5.
13. Operators assigned to each firefighting vehicle should train to respond to:
A. Only the main runway
B. All areas of the airport in all weather conditions during all flight operations
C. Only during daylight hours
D. Only the terminal area
Answer: B
Rationale: ARFF operators must be trained to respond to all areas of the airport in all weather
conditions during any flight operations that may exist, ensuring comprehensive readiness -5.
14. What are the three critical phases of flight when ARFF response is most likely needed?
A. Boarding, taxiing, and parking
B. 5 minutes after takeoff, 10 minutes before landing, and anytime aircraft is under 10,000 feet in
non-cruise
C. Takeoff, cruising, and descent
D. Pushback, engine start, and taxi
Answer: B
Rationale: The three critical phases are the first 5 minutes after takeoff, the last 10 minutes before
landing, and any time an aircraft is below 10,000 feet during non-cruise flight -16.
15. What is the purpose of a designated isolation area at an airport?
A. Parking for ARFF vehicles
B. Temporary parking for aircraft experiencing problems such as hijacking, bomb threats, or terrorist
attacks
C. Fuel storage
D. Maintenance hangar space
Answer: B
Rationale: Designated isolation areas are predetermined locations for temporarily parking aircraft
experiencing security or safety problems, keeping them away from populated areas -16.
16. What is the most common form of aircraft refueling at airports?
A. Underground pipeline system
B. Tank truck with capacities from 500 to 10,000 gallons
