The Runway Safety Area (RSA) is defined as the area that extends 1, 000 ft from the ends and 250 ft to either side of the runway center line. It is depicted as a red and white crosshatch overlay. RSA (extends 250' either side of runway) RSA Alerts & Incursion Waypoints Progressive RSA Alerts: As the vehicle comes within 360 ft to 180 ft of the nearest RSA, a YELLOW Progressive RSA Alert with the remaining distance to the RSA is displayed. SafeTaxi® & Airport Hot Spots safetaxi® SafeTaxi® gives greater map detail when viewing airports at close range. When viewing at ranges close enough to show the airport detail, the map reveals taxiways with identifying letters/numbers, runway incursion "Hot Spot", and airport landmarks including ramps, buildings, control towers, and other prominent features. Resolution is greater at lower map ranges. Accessing Quick Settings Adjusting the volume: 1) With the unit on press the POWER Button to access the Quick Settings. A blue `X' will appear over As the vehicle comes within 180 ft to 50 ft of the nearest RSA, an aural tone is played at an increasing rate based on the distance to the RSA. As the vehicle comes within 50 ft of the RSA, a RED Progressive Runway Alert is displayed and the aural tone continues to sound at an increasing rate. airPort hot sPots Airport Hot Spots are outlined to caution pilots and airport vehicles of areas on an airport surface where positional awareness confusion or runway incursions happen most often.
