Plain English Meaning
The taxiway labeled with the letter B. Pilots and controllers say 'Bravo' instead of 'B' so the name cannot be confused with another letter over the radio.
Full Definition
An example of a named taxiway at an airport, identified by the letter B and spoken as 'Bravo' using the ICAO phonetic alphabet. Taxiways are the paved paths that connect runways, ramps, and parking areas, and each one is given a letter (or letter-number combination) so it can be referenced clearly on charts, signs, and radio calls.
Context Anchor
Seen on airport taxiway signs, pavement markings, airport diagrams, and heard in ground-control instructions.
