Free AVOP Airside Markings and Lighting Questions and Answers 1

Question 1

While driving on a taxiway, you observe that the centerline lights have changed from solid green to an alternating green and yellow pattern. What does this indicate?

Accepted Answer

You are within an Instrument Landing System (ILS) critical area and must exit promptly.

Answer

Alternating green and yellow taxiway centerline lights are used to provide visual guidance to pilots and vehicle drivers that they are within the runway environment or an Instrument Landing System (ILS) critical area. These areas must be kept clear for aircraft operations, especially during low visibility conditions.

Question 2

You are operating a vehicle on the airside at night and need to proceed along a taxiway. What color lights should you expect to see outlining the edges of the taxiway?

Accepted Answer

Blue

Answer

Taxiway edge lights are always blue to distinguish them from runway edge lights, which are white. This color coding is a critical safety feature to prevent accidental incursion onto a runway.

Question 3

A large white 'X' marking is painted on a runway surface. Which of the following does this marking signify?

Accepted Answer

The runway is temporarily unserviceable and closed to all operations.

Answer

A large white 'X' indicates that a runway or aerodrome is unserviceable and closed. If the closure is temporary, these markings might be placed at each end of the runway. For permanent closures, all runway markings are obliterated and crosses are placed along its length.

Question 4

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?

Accepted Answer

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

Answer

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.

Question 5

You are driving on an airside service road that is delineated by white markings. This road intersects with a taxiway, which is marked with yellow lines. At the intersection, which of the following is the correct procedure?

Accepted Answer

Come to a complete stop and yield the right-of-way to all aircraft.

Answer

Aircraft always have the right-of-way over vehicles on the airside. Vehicle roadway markings are white, while taxiway markings are yellow. When a vehicle road intersects a taxiway, the vehicle operator must stop and yield to any taxiing aircraft. This is a fundamental rule of airside safety.
