1. What is the primary mission of Aircraft Rescue
and Firefighting (ARFF)?
A) To perform structural firefighting
B) To provide rescue and fire suppression capabilities
at aircraft incidents
C) To provide emergency medical services on the
flight line
D) To conduct aircraft maintenance
Answer: B
Rationale: The primary mission of ARFF is to provide
rescue and fire suppression capabilities at aircraft
incidents, ensuring life safety and fire control .
2. According to NFPA 403, what is the maximum
response time for the first ARFF vehicle to reach
,the midpoint of the farthest runway?
A) 1 minute
B) 2 minutes
C) 3 minutes
D) 5 minutes
Answer: C
Rationale: NFPA 403 requires the first ARFF vehicle to
reach the midpoint of the farthest runway within 3
minutes of the alarm .
3. Runway numbers are based on which of the
following?
A) True north magnetic variation
B) Magnetic heading rounded to the nearest ten
degrees
C) Latitude of the airport
D) Length of the runway in thousands of feet
Answer: B
Rationale: Runway numbers correspond to the
magnetic heading of the runway's direction, rounded
,to the nearest ten degrees and truncated to two
digits .
4. The Critical Rescue and Fire Fighting Access
Area (CRFFAA) is primarily defined to ensure:
A) Minimum distance for aircraft parking
B) Unobstructed vehicle access for ARFF apparatus
within a set radius of the runway centerline
C) Location of passenger boarding gates
D) Placement of fuel farms
Answer: B
Rationale: CRFFAA designates the cleared area
around the runway that allows ARFF vehicles to
reach an incident quickly without obstacles .
5. Which lighting system provides visual
guidance for aircraft taxiing on the movement
area?
A) Runway edge lights (white)
B) Blue taxiway lights
C) Approach Lighting System (ALS)
D) Strobe beacon lights
, Answer: B
Rationale: Blue lights are installed along taxiways to
delineate the taxi path for pilots .
6. In an uncontrolled airport, which
communication protocol must a pilot use to
coordinate with ARFF personnel before landing?
A) ATC Tower frequency
B) Common Traffic Advisory Frequency (CTAF)
C) Ground Control frequency
D) No communication is required
Answer: B
Rationale: At uncontrolled fields, pilots broadcast
intentions on the CTAF, which ARFF personnel
monitor for safety .
7. What is the ramp temperature at an airport
typically in relation to the ambient air
temperature?
A) 5° to 15° lower
B) 10° to 20° higher
C) 25° to 45° higher
