Which sign identifies the taxiway on which the aircraft is located?

• A. Runway Location
• B. Taxiway Location
• C. ILS Critical Area Boundary
• D. Runway Safety Area Boundary

Answer: (B)

Understanding where you are on the airfield comes from the signs that identify your current position. A taxiway location sign is the one that tells you the exact taxiway you are on, typically displayed at intersections to confirm you’ve reached the intended route. This sign usually has a dark background with contrasting lettering showing the taxiway designation, so it serves as a precise reference for your present location on the taxiway network.

The other signs serve different purposes: a runway location sign would tell you which runway you are on rather than which taxiway; ILS critical area boundary signs mark the boundary of the protected ILS area, and runway safety area boundary signs mark the edge of the runway safety area. None of these indicate the taxiway you’re currently on, so they’re not used for identifying the taxiway in use.
