Fuel spills create fire hazards, so engines and ignition sources must be shut off and the area cleared.

Question 83: One statute mile equals about how many nautical miles?

0.87 NM (Correct answer)
1.15 NM
1.61 NM
0.62 NM

Correct answer: 0.87 NM

A nautical mile is about 1.15 statute miles, so one statute mile is about 0.87 NM.

Question 84: Which weather condition requires that outdoor fueling operations be temporarily suspended?

Wind speeds above 10 mph
Visibility below one mile
Active lightning within 5 miles of the airport (Correct answer)
Temperature below 32°F

Correct answer: Active lightning within 5 miles of the airport

Active lightning within 5 miles requires suspension of fueling operations because lightning can ignite fuel vapors and cause a catastrophic fire.

Question 85: What is the main hazard when a high-lift catering truck is raised near an aircraft door?

Running out of fuel
Contact with the fuselage as the aircraft settles during unloading (Correct answer)
Excessive engine noise
Overheating of food carts

Correct answer: Contact with the fuselage as the aircraft settles during unloading

Aircraft rise or settle as weight changes, so the raised platform must be monitored to avoid damaging the door or fuselage.

Question 86: What should the operator do if a towbar shear pin breaks during pushback?

Increase speed to finish the push
Disconnect and drive away
Stop the tug and notify the flight crew to set brakes (Correct answer)
Continue pushing slowly

Correct answer: Stop the tug and notify the flight crew to set brakes

A broken shear pin means the tug no longer controls the aircraft, so the crew must stop it with the aircraft brakes.

Question 87: What must be done before towing an aircraft across an active taxiway or intersection?

Notify the destination gate agent and wait for acknowledgment
Sound the tug horn three times to warn other vehicles
Stop and allow all other ground vehicles to clear first
Obtain ATC clearance and post wing walkers as required (Correct answer)

Correct answer: Obtain ATC clearance and post wing walkers as required

ATC clearance is required before crossing active taxiways or runways, and wing walkers are typically required to guide the aircraft safely through intersections.

Question 88: What is the approximate weight of one US gallon of Jet A fuel at standard temperature?

8.3 lb
5.2 lb
7.9 lb
6.7 lb (Correct answer)

Correct answer: 6.7 lb

Jet A has a density of about 6.7 lb per US gallon at 15°C.

Question 89: What is the holdover time for deicing fluid?

The minimum time an aircraft must wait before takeoff after deicing
The time needed to flush the deicing truck lines
The estimated time the fluid remains effective after application (Correct answer)
The time required to complete a full deicing application

Correct answer: The estimated time the fluid remains effective after application

Holdover time is the estimated period during which deicing fluid prevents ice accumulation after application, varying by fluid type and weather conditions.

Question 90: Before a belt loader is driven up to an aircraft cargo door, what should the operator do with the conveyor belt?

Lower it fully and approach with it retracted (Correct answer)
Run the belt in reverse during the approach
Raise it to door height while driving
Leave it at any height and adjust once stopped

Correct answer: Lower it fully and approach with it retracted

Approaching with the belt lowered and retracted gives better visibility and reduces the chance of striking the fuselage.

Question 91: How should hazardous conditions be handled during technical measurements work?

Report hazards only at the end of the day
Continue working if the hazard seems minor
Stop work, secure the area, report the hazard, and follow safety protocols (Correct answer)
Let someone else deal with it

Correct answer: Stop work, secure the area, report the hazard, and follow safety protocols

All hazardous conditions require immediate action: stop work, secure the area, report the hazard, and follow established safety protocols.

Question 92: Which equipment is commonly used to tow aircraft on the ground?

Belt loader
Fuel truck
Cargo loader
Pushback tug (Correct answer)

Correct answer: Pushback tug

A pushback tug, also known as an aircraft tractor, is a specialized ground support vehicle used to push an aircraft away from the gate or tow it to other areas of the airport. Aircraft typically cannot reverse under their own power without causing jet blast damage to terminal buildings or other equipment. Tugs are therefore essential for safely maneuvering aircraft on the ground.

Question 93: A ramp agent reads 30°C on the ramp thermometer. What is that in Fahrenheit?

86°F (Correct answer)
72°F
98°F
54°F

Correct answer: 86°F

°F = (°C × 9/5) + 32, so 30°C equals 86°F.

Question 94: When conducting a fuel quality check before uplift, the ramp agent should check for which contamination?

Water and particulate matter (Correct answer)
Fuel temperature only
Fuel color saturation level
Carbon deposits only

Correct answer: Water and particulate matter

Fuel sumping checks for water and particulate contamination, both of which can cause engine flameout or fuel system blockages.

Question 95: While marshalling, the marshaller loses sight of the wing walker. What should the marshaller do?

Signal the aircraft to stop until the wing walker is visible again (Correct answer)
Continue at a slower speed
Wave the aircraft forward and look for the wing walker after parking
Hand control to the flight crew

Correct answer: Signal the aircraft to stop until the wing walker is visible again

Without the wing walker's clearance signals, wingtip clearance cannot be confirmed, so the aircraft must stop.

Question 96: What is the purpose of a preconditioned air (PCA) unit at the gate?

To inflate the aircraft tires
To pressurize the hydraulic system
To supply bleed air for engine start
To heat or cool the cabin without running the APU (Correct answer)

Correct answer: To heat or cool the cabin without running the APU

PCA supplies conditioned air to the cabin, reducing APU use, fuel burn, and emissions.

Question 97: What type of fire extinguisher is required to be present and accessible during aircraft fueling operations?

Class B CO2 or dry chemical extinguisher (Correct answer)
Class D metal powder extinguisher
Class A water extinguisher
Class C halon extinguisher

Correct answer: Class B CO2 or dry chemical extinguisher

Class B extinguishers rated for flammable liquid fires are mandatory during fueling because aviation fuel is a flammable liquid.

Question 98: Under 49 CFR Part 1542, a SIDA badge holder who allows an unbadged person to follow them through a controlled door is committing what violation?

FOD contamination
Badge sharing
Piggybacking/tailgating (Correct answer)
Unauthorized fueling

Correct answer: Piggybacking/tailgating

Allowing someone through an access point without their own badge is piggybacking, a security violation.

Question 99: A ramp scale shows 2,200 lb for a ULD with a tare weight of 180 lb. What is the net cargo weight?

2,200 lb
1,820 lb
2,020 lb (Correct answer)
2,380 lb

Correct answer: 2,020 lb

Net = gross − tare = 2,200 − 180 = 2,020 lb.

Question 100: Which area of the airport requires drivers to have specific movement-area authorization and usually ATC clearance?

Baggage makeup room
Runways and taxiways (movement area) (Correct answer)
The terminal curb
Employee parking lot

Correct answer: Runways and taxiways (movement area)

Entering the movement area requires ATC clearance and specialized driver training to prevent runway incursions.
