a) To indicate the location of taxiways

b) To guide aircraft during landing and takeoff

c) To indicate obstacles near the runway

b) To guide aircraft during landing and takeoff

Rationale: Runway edge lights are used to outline the edges of the

runway at night or during low visibility, helping pilots maintain alignment.

• What color are taxiway edge lights?

a) White 1 / 4

b) Blue

c) Green

b) Blue

Rationale: Taxiway edge lights are blue to distinguish taxiways from

• What type of light system is used to assist pilots during approach in

low visibility?

a) Taxiway lights

b) Approach lighting system (ALS)

c) Runway end identifier lights (REIL)

b) Approach lighting system (ALS)

Rationale: ALS provides visual guidance to pilots on final approach,

especially in low visibility conditions.

• What is the function of runway end identifier lights (REIL)?

a) To indicate the threshold of the runway

b) To illuminate taxiway intersections 2 / 4

c) To mark runway obstacles

a) To indicate the threshold of the runway

Rationale: REILs consist of flashing lights at the runway threshold to

help pilots identify the runway beginning from a distance.
