Plain English Meaning

A sign that tells you the name of the taxiway you are on right now. Black background, yellow letter, yellow border.

Full Definition

A black square sign with a yellow letter or letters and a yellow border, used at airports to identify the taxiway on which the aircraft is currently located.

Context Anchor

Seen while taxiing on the airport movement area, often along the side of a taxiway or grouped with other taxiway signs.

Derivation

‘Location’ comes from Latin locus, meaning ‘a place.’ The sign tells you the place — the taxiway — you are on.

Why Pilots Care

Confirms exact position during ground movement and reduces the chance of entering the wrong area or runway.

Analogy

It works like a mall map marker that says “You are here,” except it names the taxiway your aircraft is already on.
