What do hotspots on a aeronautical chart look like?

Hotspots on an aeronautical chart are specifically designated areas that indicate potential hazards or areas that require special attention during taxiing operations. These hotspots are depicted as magenta circles and are marked with the notation "HS" followed by a number, such as "HS1," "HS2," etc. This visual representation helps pilots quickly identify areas where there may be increased risk of runway incursions or where attention to standard operating procedures is critical.

The use of color and symbol, particularly the magenta circle, makes hotspots easily distinguishable on the chart, allowing for a clear and efficient way to communicate important information to pilots. Understanding this format is vital for safe ground operations at busy airports, where awareness of potential hazards is crucial to prevent accidents.
