Airport hotspots are areas on airport grounds that have a history of potential collision or runway incursion risks, requiring pilots, drivers, and controllers to be extra vigilant. These hotspots are marked on airport diagrams, which can be found in the Chart Supplement section of the Terminal Procedures – Basic Search page. Hotspots are designated with HS followed by a number, and they are coloured either brown or red depending on the chart type. Hotspots can be found at various airports, including Class B airports like Miami International and smaller airports like Crookston, MN (KCKN). To improve situational awareness, pilots can refer to airport diagrams and briefing resources before taxiing.

Hot spots are marked in brown on FAA charts and red on Jeppesen charts
Hot spots are areas in airports that require heightened attention from pilots, drivers, and controllers due to their history or potential risk of collision or runway incursion. These areas are marked on airport diagrams, which can be found in the airport diagrams section of the Chart Supplement.
Hot spots are designated with "HS" (for "hot spot") followed by a number. While there is currently no standard shape for designating hot spots, they are often marked with circles, boxes, or ellipses on taxi diagrams. As of May 19, 2022, the Federal Aviation Administration (FAA) has introduced a standardized symbology for hot spots, using three shapes with two distinct meanings: a circle or ellipse for ground movement hot spots and a cylinder for wrong surface hot spots.
When using FAA charts, hot spots are marked in brown, while on Jeppesen charts, they are marked in red. It is important to note that some small airports may not have charted hot spots, even when one is needed. Therefore, it is crucial to brief any hot spots along your taxi route before beginning taxiing and to have a taxi diagram readily available to improve situational awareness.
Additionally, the FAA is introducing Arrival Alert Notices (AAN) at airports with a history of misalignment risk. These notices provide a graphic visualization of the approach to the airport, aiding pilots in navigating safely.

Hot spots are defined as locations with a history or potential risk of collision
Hot spots are not unique to large, busy airports; they can also be found at smaller airports. For example, Hot Spot 2 at KBJC has a unique set of challenges due to the positioning of its hold short line in front of Taxiway B. Pilots need to be aware that, after landing on Runway 12R, they must exit to the right on D2, taxi northwest on D, and then hold short of Runway 3 before turning onto Taxiway B. This is an unusual setup, as the aircraft does not actually cross Runway 3.
Miami International Airport, a Class B airport, also has a well-known hot spot. Hot Spot 5 is located at the convergence of Taxiways M, P, and Q, with Runway 8R and Runway 12. Due to the compact spacing, there are two sets of hold short lines.
To improve safety, the FAA is standardizing hot spot symbology and verbiage. As of May 19, 2022, hot spots are depicted by three shapes with two distinct meanings: a circle or ellipse for ground movement hot spots and a cylinder for wrong surface hot spots. This standardization aims to improve clarity and consistency in airport diagrams.

Hot spots are marked by circles or boxes on taxi diagrams
Hot spots are areas of an airport that are considered hazardous due to their potential risk of collision or runway incursion, requiring heightened attention from pilots, drivers, and controllers. They are typically found at intersections between taxiways and runways, where pilots may confuse a taxiway for a runway or vice versa. These areas are marked on taxi diagrams to alert pilots of the potential dangers.
Previously, there was no standard shape to designate a hot spot on airport diagrams, and they were often charted with various shapes like squares, rectangles, circles, ovals, and ellipses. However, starting May 19, 2022, the Federal Aviation Administration (FAA) standardized the symbology for hot spots. Now, hot spots are marked by circles or boxes (cylinders) on taxi diagrams, with two distinct meanings: a circle or ellipse for ground movement hot spots and a cylinder for wrong surface hot spots. These symbols are consistent across airport diagrams and chart supplements, making it easier for pilots to identify and navigate these hazardous areas.
The hot spot locations are described in the airport diagrams section of the Chart Supplement, which can be found in the Additional Resources section of the Terminal Procedures – Basic Search page. Hot spots are designated with "HS" for "hot spot" followed by a number. If you're using Jeppesen Charts, hot spots are marked in red, while FAA Charts use brown. It's important for pilots to be aware of these hot spots and have a plan in place for handling them to ensure safe taxiing and runway operations.
As an example of a hot spot, let's consider Miami International Airport, a Class B airport. Hot Spot 5 is located at the convergence of Taxiways M, P, and Q, near the arrival end of Runway 8R and Runway 12. The compact spacing at this hot spot requires two sets of hold short lines to ensure pilots don't inadvertently enter the runway. This example highlights the importance of being vigilant and aware of hot spots during taxi procedures.

Hot spot symbols are standardised by the FAA
Hot spots are areas on airport diagrams that indicate complex or confusing taxiway and runway intersections with a history or potential risk of collision or runway incursion. These areas require heightened attention from pilots, drivers, and controllers.
Previously, there was no standard shape used to designate a hot spot, and they were often charted with a variety of squares, rectangles, circles, ovals, and ellipses, leading to inconsistencies and potential confusion. To address this issue, the Federal Aviation Administration (FAA) began standardizing hot spot symbology and verbiage on airport diagrams within chart supplements and the Terminal Procedures Publication.
Starting May 19, 2022, the FAA introduced three standardized shapes with two distinct meanings: a circle or ellipse for ground movement hot spots and a cylinder for wrong-surface hot spots. Ground movement hot spots refer to areas with a history or potential risk of collision or runway incursion, requiring extra caution from pilots, drivers, and controllers. Wrong-surface hot spots, on the other hand, indicate locations where aircraft have inadvertently attempted to depart or land on the wrong surface, presenting a significant safety risk that the FAA has been focusing on addressing.
The FAA is also introducing Arrival Alert Notices (AANs) at airports with a history of misalignment risk. These AANs provide graphic visuals of the approach to these airports, incorporating the new standardized hot spot symbology. By standardizing hot spot symbols and providing additional alerts, the FAA aims to enhance safety and prevent incidents related to runway incursions and wrong-surface events.

Hot spots can be found on ForeFlight's Aeronautical Map layer
Hot spots on airport diagrams appear as orange highlighting on top of runways, taxiways, and aprons. Each hot spot includes a label similar to those found in ForeFlight's PDF airport diagrams. These labels can be found in the airport diagrams section of the Chart Supplement. The complete list of all Chart Supplement Hot Spot Info can be found under the heading Additional Resources on the Terminal Procedures – Basic Search page.
The different types of hot spots include ground movement hot spots and wrong surface hot spots. Ground movement hot spots are depicted by a circle or ellipse and include issues such as potential risks of collision or runway incursion. Wrong surface hot spots, on the other hand, depict locations where an aircraft has inadvertently attempted to or actually departed or landed on the wrong surface.
In addition to hot spots, ForeFlight also provides access to weather station information. This can be accessed by enabling a suitable weather layer and tapping on a weather station on the map.
