Mixed Deck — All AVOP Topics Flashcards

What does a black sign with yellow text and yellow border indicate?

Answer: Your current location on the airfield

Location signs have black backgrounds with yellow text and border, showing your current position.

What does a steady red light signal from the ATC tower mean to a ground vehicle operator?

Answer: Stop

A steady red light from the control tower is an instruction for the vehicle to stop immediately.

What is a FOD walk?

Answer: A systematic inspection of airside pavement to collect debris

A FOD walk is a systematic sweep of airside pavement areas where personnel walk in a line to visually identify and collect any debris.

What is your responsibility regarding suspicious unattended items found on the airside?

Answer: Do not touch; report location to security immediately

Never touch suspicious items. Report the exact location and description to airport security.

What is required before a ground vehicle crosses an active runway at a controlled airport?

Answer: Explicit verbal clearance from ATC specifically authorizing the runway crossing

At a controlled airport, a vehicle must receive explicit ATC clearance — including the runway designation — before crossing any active runway.

To avoid confusion with similar-sounding letters over the radio, the ICAO phonetic alphabet is used. How would you correctly spell out "TAXIWAY B9"?

Answer: "TAXIWAY, BRAVO, NINER."

The word "Taxiway" is standard and does not need to be spelled out. The letter 'B' is "Bravo" in the ICAO phonetic alphabet, and the number '9' is pronounced "Niner" to avoid confusion with the number '5' (Fife).

What vehicles are typically prohibited from the movement area?

Answer: Personal and unauthorized commercial vehicles

Personal vehicles and unauthorized commercial vehicles are prohibited. Only specifically authorized vehicles may enter.

What is the proper procedure for refueling a vehicle on the airside?

Answer: Use designated areas, shut off engine, ground if required, have fire equipment available

Refuel at designated locations with engine off, proper grounding, and fire equipment available.

When must a vehicle operator activate their rotating beacon or amber flashing light?

Answer: At all times while operating on the airside

Amber rotating beacons must be activated at all times while on the airside.

What does the term "Connecting Corridor" mean?

Answer: A vehicle route marked on the mobility area that crosses the taxiway for an aircraft stand

The term "Connecting Corridor" typically refers to a vehicle route marked on the mobility area that crosses the taxiway for an aircraft stand. This corridor provides access for vehicles to move between different areas of the airport, such as terminals, hangars, or other facilities. So, the correct option from the provided choices is: "A vehicle route marked on the mobility area that crosses the taxiway for an aircraft stand."

As a vehicle operator approaching a runway holding position, you see a pair of elevated, flashing yellow lights, one on each side of the taxiway. What are these lights called and what is their primary purpose?

Answer: Runway Guard Lights; to enhance the conspicuity of the runway holding position.

Runway Guard Lights consist of either elevated flashing yellow lights or a row of in-pavement yellow lights at the runway holding position. Their primary purpose is to warn pilots and vehicle operators that they are approaching an active runway, thereby helping to prevent runway incursions, especially in low visibility conditions.

What is the significance of reading back an ATC runway crossing clearance?

Answer: It confirms mutual understanding between ATC and the vehicle operator and allows ATC to correct any error before the crossing

Reading back ATC clearances, including runway crossing instructions, creates a closed communication loop that allows ATC to catch and correct any misunderstanding before the vehicle enters the runway.

During low visibility operations (LVO) on the airside, what is a key additional precaution for vehicle operators?

Answer: Reduce speed, use radio communications more frequently, and confirm position before proceeding across any holding point

Low visibility conditions increase the risk of disorientation and incursions, so operators must slow down, communicate more actively with ATC, and verify their position before crossing any runway holding point.

What does a sign with 'ILS' on a red background indicate?

Answer: ILS Critical Area—do not enter when ILS is in use

This mandatory sign marks the ILS critical area boundary.

What does a surface-painted holding position sign look like on taxiway pavement?

Answer: White text on red background

Surface-painted holding position signs have white text on a red background, matching elevated mandatory instruction signs.

What is the aerodrome traffic circuit and why should operators understand it?

Answer: The defined flight path aircraft follow for landing, affecting busy areas

Understanding the traffic circuit helps anticipate where aircraft fly at low altitude.

What does a yellow sign with black text and directional arrows indicate?

Answer: Direction and designation of intersecting taxiways

Direction signs have yellow backgrounds with black text and arrows pointing toward identified taxiways.

What marks a displaced threshold on a runway?

Answer: White arrows pointing toward the threshold bar

White arrows lead to the displaced threshold marked by a white bar.

What role do AVOP holders play in wildlife hazard management?

Answer: Serve as additional observers, reporting sightings and strikes

AVOP holders extend the airport's ability to detect wildlife across the entire airfield.

What federal regulation governs airport security programs including access control?

Answer: 49 CFR Part 1542

49 CFR Part 1542 establishes requirements for airport security programs including access control.
