This information on runway incursions is a way to analyze breakdowns or holes in the Air Traffic system. They can show what, how and why an event occurred. They can happen in numerous ways and can be caused by any combination of errors, fatigue, negligence, etc. Luckily the Runway Safety Office has set a goal in accordance with FAA Call to Action to lower incursions to less than 50% from the previous year.
Operational Errors | Pilot Deviations | Vehicle/Pedestrian Deviation |
---|---|---|
Action of an Air Traffic Controller that results in: Less than required minimum separation between 2 or more aircraft, or between an aircraft and obstacles, (vehicles, equipment, personnel on runways) or Clearing an aircraft to take off or land on a closed runway | Action of a pilot that violates any Federal Aviation Regulation Example: a pilot crosses a runway without a clearance while enroute to an airport gate | Pedestrians or vehicles entering any portion of the airport movement areas (runways/taxiways) without authorization from air traffic control |
Available Reaction Time | Evasive of Corrective Action | Environmental Conditions | Speed of Aircraft and/or Vehicle | Proximity of Aircraft and/or Vehicle |

---|---|---|---|---|
Incident that meets the definition of runway incursion such as incorrect presence of a single vehicle/person/aircraft on the protected area of a surface designated for the landing and take-off of aircraft but with no immediate safety consequences. |
An incident characterized by ample time and/or distance to avoid a collision. |
An incident in which separation decreases and there is a significant potential for collision, which may result in a time critical corrective/evasive response to avoid a collision. |
A serious incident in which a collision was narrowly avoided. |
