Aircraft lighting isn’t just about being seen—it’s about being understood by others in the air and on the ground.

Position (Navigation) Lights
Position lights are on from sunset to sunrise and indicate an aircraft’s orientation.
Red light – Left wing
Green light – Right wing
White light – Tail
From these three lights, another pilot can instantly determine:
Direction of travel
Relative movement (approaching, receding, or crossing)
If you see red and green, the aircraft is coming toward you. If you see only white, it’s moving away.
Anti-Collision Lights
Anti-collision lights increase an aircraft’s visibility and draw attention to its movement.
These include:
Rotating beacons (typically red)
Strobe lights (usually white)
Beacons are often used:
Before engine start
Anytime the aircraft is running
Strobes are most effective in flight but may be turned off on the ground or in clouds if they create disorientation or glare.
Landing and Taxi Lights
These lights serve both visibility and safety roles.
Taxi lights illuminate the ground during ground movement
Landing lights provide forward visibility during takeoff, landing, and low-level flight
Landing lights also make aircraft significantly more visible to others, especially in traffic patterns or near busy airports.
Recognition and Logo Lights
Some aircraft include:
Recognition lights (pulsing forward-facing lights)
Wing or tail logo lights
While not required, these lights:
Improve visibility
Enhance aircraft identification
Add redundancy to anti-collision systems
Airport Beacon Lights: Identifying Airports at Night
One of the most recognizable sights in night aviation is the rotating airport beacon. These high-intensity lights are designed to be visible from miles away, helping pilots locate airports in darkness or reduced visibility.
Civilian Airport Beacons
Most civilian airports use a white and green rotating beacon.
Green flashes indicate a civilian land airport
White flashes alternate with green
This combination tells pilots not just that an airport is nearby—but what type it is.
Military Airport Beacons
Military airfields use a different color pattern:
Two quick white flashes
Followed by one green flash
This distinction helps prevent confusion, especially in areas with multiple airfields.
Seaplane Base Beacons
Seaplane bases are marked by:
White and yellow flashes
The yellow component signals water operations, distinguishing them from land-based airports.
Heliport Beacons
Heliports use a more subtle combination:
Green, yellow, and white flashes
These beacons help rotorcraft pilots identify landing areas that may otherwise be difficult to see at night.
When Airport Beacons Are On (and Off)
Airport beacons are typically:
Turned on from sunset to sunrise
Activated during reduced visibility conditions
At some airports, the beacon may be:
Pilot-controlled
Turned off if the airport is closed or well-lit
Importantly, a beacon does not guarantee:
That the runway lights are on
That the airport is open or staffed
Pilots must still verify runway lighting and availability.
Common Night-Flying Misconceptions
“I see a beacon, so the runway lights must be on.” Not always. Runway lights may need to be pilot-activated.
“Strobes must always be on.”Pilots may turn them off if they reduce safety due to glare or disorientation.
“A bright light means an airport.”Towers, wind farms, and industrial sites can mimic airport lighting patterns.
Why Lighting Knowledge Matters
At night, pilots lose many visual cues:
Terrain features
Horizon definition
Distance judgment
Lighting becomes the primary source of situational awareness. Knowing how to interpret airplane and airport lights helps pilots:
Avoid midair conflicts
Navigate confidently
Reduce workload
Make better decisions under pressure
Final Thought
Night aviation isn’t about seeing everything—it’s about recognizing the right things. Airplane lights tell stories of movement and intention, while airport beacons quietly mark safe havens in the dark.
For pilots, fluency in this language of light transforms night flight from intimidating to intuitive—and keeps the sky orderly long after the sun goes down.
