What is a hot spot on an airport diagram?

• A. The location where fuel trucks park.
• B. A high-risk taxiway/runway intersection where incursions are more likely.
• C. A section of runway reserved for braking tests.
• D. A nonessential advisory marking for pilots.

Answer: (B)

A hot spot on an airport diagram marks a high-risk taxiway or runway intersection where conflicts or incursions are more likely. These areas are busy and have limited visibility or complex traffic patterns, so the chance of a pilot and controller miscommunicating or two aircraft crossing paths is greater. The diagram highlights these spots to cue extra caution—verify clearance, read back instructions, and prepare to hold short or follow specific routing as directed. The other descriptions don’t describe a high-risk intersection that could lead to incursions, which is why they aren’t the right concept for a hot spot.
