AVOP Airside Markings and Signage 2 — Questions and Answers
Question 1: What does a red sign with runway designations like '27-9' indicate?
- Runway distance
- Runway holding position—must not proceed without ATC clearance (Correct answer)
- Gate number
- Construction marker
Correct answer: Runway holding position—must not proceed without ATC clearance
A red mandatory instruction sign showing runway numbers marks a holding position requiring ATC clearance.
Red signs displaying runway numbers are mandatory instruction signs marking runway holding positions. No vehicle may proceed past without explicit ATC clearance. Crossing without authorization is a runway incursion.
Question 2: What does a black sign with yellow text and yellow border indicate?
- Direction to a taxiway
- Your current location on the airfield (Correct answer)
- A mandatory stop
- Distance remaining on runway
Correct answer: Your current location on the airfield
Location signs have black backgrounds with yellow text and border, showing your current position.
Location signs identify the taxiway, runway, or area where you are located. For example, 'A' in yellow on black means you are on Taxiway A. They are essential for navigation and communication with ATC.
Question 3: What does a yellow sign with black text and directional arrows indicate?
- Your current location
- Direction and designation of intersecting taxiways (Correct answer)
- Mandatory stop
- Closed taxiway
Correct answer: Direction and designation of intersecting taxiways
Direction signs have yellow backgrounds with black text and arrows pointing toward identified taxiways.
Direction signs at taxiway intersections indicate designation and direction of intersecting taxiways. They are informational (not mandatory) but essential for proper navigation. Follow these in conjunction with ATC routing instructions.
Question 4: What does the two-solid-two-dashed yellow line marking across a taxiway indicate?
- Taxiway closed
- Runway holding position—stop on the solid side without ATC clearance (Correct answer)
- Vehicle parking
- Taxiway edge
Correct answer: Runway holding position—stop on the solid side without ATC clearance
This runway holding position marking means stop before the solid lines.
Four yellow lines spanning the taxiway: two solid on the taxiway side, two dashed on the runway side. Never cross from solid to dashed without ATC clearance. These are the most important pavement markings on the airfield.
Question 5: What is a destination sign at an airport?
- Mandatory stop
- Direction to a specific destination like a runway or terminal (Correct answer)
- Current position
- Emergency evacuation route
Correct answer: Direction to a specific destination like a runway or terminal
Destination signs have yellow backgrounds with arrows directing toward specific locations.
Destination signs indicate routes to specific destinations: runways, terminals, cargo facilities. They feature yellow backgrounds with black text and arrows. Vehicle operators use them with direction signs and ATC instructions for navigation.
Question 6: What does enhanced taxiway centerline marking at an intersection look like?
- Solid white line
- Dashed yellow with widened dashes (Correct answer)
- Red paint across full width
- Blue dashes
Correct answer: Dashed yellow with widened dashes
Enhanced centerline markings with wider dashes alert operators to intersections.
At taxiway intersections, enhanced centerline markings (wider dashes or additional markings) alert operators to the intersection. Reduce speed and increase vigilance, scanning for aircraft and vehicles that may be crossing.
