Mixed Deck — All ARS Topics Flashcards

What is the purpose of a wing walker during aircraft pushback or towing?

Answer: To ensure wingtip clearance from obstacles and signal the tug driver to stop if needed

Wing walkers watch wingtip clearance and can stop the movement to prevent collisions.

Which special handling code identifies a shipment of radioactive material?

Answer: RRY

RRY is the IATA code for radioactive material Category II and III (Yellow labels).

How must galley waste from an international arrival be handled in the U.S.?

Answer: As USDA APHIS regulated garbage, in sealed containers for approved disposal

USDA APHIS regulates international food waste so foreign plant and animal diseases don't enter the U.S.

Which deicing fluid type is selected mainly for longer anti-icing holdover time?

Answer: Type IV

Type IV is a thickened fluid that provides the longest holdover protection against refreezing.

Per NFPA 407 guidance, a fuel spill becomes large enough to require notifying the airport fire department when it exceeds what size?

Answer: 10 feet in any dimension or 50 sq ft

Spills over 10 feet in any dimension or 50 square feet in area require fire department notification.

A ramp agent notices hydraulic fluid leaking from an aircraft's landing gear. What should they do?

Answer: Report it immediately to maintenance or the flight crew

Fluid leaks can indicate a mechanical problem and must be reported so maintenance can evaluate airworthiness.

Before a towbar pushback, why must the nose-wheel steering bypass pin be installed?

Answer: To depressurize the nose-wheel steering so the tug can turn the nose gear without fighting the aircraft's hydraulics

The bypass pin disables hydraulic nose-wheel steering so the tug can steer without damaging the steering system.

Which PPE item is specifically critical for ground crew conducting aircraft towing operations at night?

Answer: High-visibility vest or reflective clothing

High-visibility reflective vests ensure ground crew are seen by tug operators, other vehicle drivers, and cockpit crew in low-light and nighttime conditions.

Why are aluminum alloys commonly used for unit load devices (ULDs) such as containers and pallets?

Answer: They offer high strength with low weight

Aluminum provides a strong strength-to-weight ratio, which matters for aircraft weight limits.

Where must a SIDA badge generally be worn while working on the ramp?

Answer: Above the waist on the outermost garment, clearly visible

Airport security programs require the badge to be displayed above the waist on the outer garment.

When charging electric GSE batteries, which safety practice is most important?

Answer: Charge only in a well-ventilated area away from sparks and open flames

Lead-acid batteries release hydrogen gas while charging, which can explode if it builds up near an ignition source.

What environmental protection measure applies to quality inspection?

Answer: Proper handling, storage, and disposal of materials according to environmental regulations

Proper handling, storage, and disposal of all materials according to environmental regulations is a legal obligation in all trades.

What code compliance requirement applies to environmental standards?

Answer: All work must comply with applicable local, state, and national codes

Code compliance is mandatory for all work, ensuring safety, quality, and legal adherence.

Where are safety cones typically placed around a parked commercial aircraft?

Answer: At the wingtips, engines, and tail to mark the aircraft's outline and hazard points

Cones at the extremities and engines keep GSE drivers clear of parts that are easy to strike.

An audit shows an agent riding on a moving baggage cart. How should this be classified?

Answer: A safety violation requiring correction and coaching

Riding on carts or equipment not designed for passengers is prohibited because falls can cause serious injury.

When approaching a spill of an unknown hazardous material on the ramp, how should personnel position themselves?

Answer: Upwind and uphill of the spill

Staying upwind and uphill keeps responders away from vapors and flowing liquid.

Which bags should normally be loaded last into the bulk hold so they are offloaded first at arrival?

Answer: Priority and short-connection transfer bags

Last-in, first-out loading puts priority and tight-connection bags near the door so they come off first.

A loose bag strap is spotted on the apron near an aircraft's engine inlet before pushback. What does code compliance require?

Answer: Remove it immediately and dispose of it in a FOD container

FOD must be picked up immediately to prevent engine ingestion damage.

What is the main environmental purpose of a designated deicing pad?

Answer: To collect spent deicing fluid for recovery or treatment

Deicing pads drain to collection systems so glycol can be captured instead of running off into stormwater.

A Unit Load Device's tare weight refers to:

Answer: The weight of the empty ULD

Tare weight is the ULD's own empty weight, which is added to the cargo weight to get gross weight.
