Definition
Taxiway lights that emit light visible from all directions around the fixture, used at certain locations on an airport movement area to mark hazards, hold positions, or other features that must be seen regardless of the pilot's approach direction. They contrast with standard taxiway edge lights, which are directional or limited in their viewing angle.
Plain English
Taxiway lights that shine in every direction, so a pilot can see them no matter which way they are taxiing.
Context Anchor
Seen on airport movement areas during taxi, especially at night or when visibility is reduced.
Derivation
Omni' comes from Latin 'omnis' meaning 'all,' and 'directional' refers to direction. Together, omnidirectional means 'in all directions' — a light visible from every angle.
Why Pilots Care
They provide continuous visual guidance on the surface, reducing the risk of excursions or runway incursions.
Intuition Check
Omnidirectional does not mean the lights tell you which direction to taxi. It means each light can be seen from every direction around it.
Example Sentence 1
The hold-short position was marked at night by omnidirectional taxiway lights, visible to the pilot whether approaching from the apron or the parallel taxiway.
Example Sentence 2
At night the omnidirectional taxiway lights outlined the path clearly from any angle on the airport surface.
