Hot Spot Standardized Symbology

Hot Spot Standardized Symbology

A hot spot is a location on an airport movement area with a history or potential risk of collision or runway incursion, and where heightened attention by pilots and drivers is necessary.

It is easier for users of an airport to plan the safest possible path of movement in and around that airport if they can see the hot spots. Planning is a crucial safety activity for airport users — pilots, air traffic controllers and airfield drivers. By making sure that aircraft surface movements are planned and properly coordinated with air traffic control, pilots add another layer of safety to their flight preparations. Proper planning helps avoid confusion by eliminating last-minute questions and building familiarity with known problem areas.

Hot Spot Standardized Symbology

The FAA is taking several proactive steps to address wrong surface events, reduce the potential for runway confusion and help improve safety in the National Airspace System (NAS), including standardizing hot spot symbology and verbiage. Currently, there is no standard shape to designate a hot spot on airport diagrams within chart supplements and the Terminal Procedures Publication; they are charted with a variety of squares, rectangles, circles, ovals, and ellipses with no pattern or consistency. Beginning May 19, 2022, the FAA will standardize these symbols to three shapes with two distinct meanings: a circle or ellipse for ground movement hot spots and a cylinder for wrong surface hot spots.


Today, as depicted in the Lincoln, NE (LNK) FAA Airport Diagram, you can see a myriad of shapes for Hot Spots.

Arrival Alert Notices

To address wrong surface events where an aircraft lines up with or lands on the incorrect runway, taxiway, or airport, the FAA is releasing Arrival Alert Notices (AAN) at several airports with a history of misalignment risk. AANs will incorporate the new standardized hot spot symbology. Learn more about Arrival Alert Notices.
