DLH Runway Incursion & Surface Incidents
• Runway Incursion: the incorrect presence of an aircraft, vehicle or person on the protected area of a surface designated for the landing and take off of aircraft.
• Surface Incident: an unauthorized or unapproved movement within the designated movement area (excluding runway incursions) or an occurrence in that same area associated with the operation of an aircraft that affects or could affect the safety of flight.
21 1/5/2020
DLH Runway Incursion & Surface Incidents
• Operational Incident: • 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 • Pilot Deviation: • Action of a pilot that violates any Federal Aviation Regulation • Vehicle/Pedestrian Deviation: • Pedestrians or vehicles entering any portion of the airport movement areas (runways/taxiways) without authorization from air traffic control

Taxiway Design
• Good design practices keep taxiway intersections simple. • Complex layouts increase the possibility of pilot error. • Three-node concept – A pilot has no more than 3 choices at an intersection – ideally, left, right and straight ahead. • Intersection angles – Design turns to be 90 degrees wherever possible.
41 1/5/2020
Design to Reduce Runway Incursions
• Increase situational awareness, keep taxiway systems simple. • Avoid wide expanses of pavement. • Limit runway crossings. • Avoid “dual purpose” pavements • Avoid “high energy” intersections (middle 1/3 of the runway). • Avoid direct access to runways • Increase visibility – Right angle intersections provide the best visibility.
42 1/5/2020
Problematic Taxiway Design - Examples
• Wide expanse of pavement: Reduces pilot’s ability to see visual cues (signs, etc.)
43 1/5/2020
Problematic Taxiway Design - Examples
• Direct access from Ramp to Runway: May create false expectation of a parallel taxiway prior to the runway.
44 1/5/2020
Problematic Taxiway Design - Examples
• Greater than 3-node intersection: May lead to pilot confusion. Difficult to properly locate signs.
45 1/5/2020
Problematic Taxiway Design - Examples
• Intersection at other than 90 degrees. Does not provide best visual perspective to a pilot.
46 1/5/2020
Problematic Taxiway Design - Examples
• Short taxi distance from ramp to runway. Pilots must complete the same number of checklist items in a short distance. Chances of incursions increase in that head-down period
47 1/5/2020
Problematic Taxiway Design - Examples
• Unexpected hold line location: The placement is unexpected and pilots may ignore/not expect the hold position point, increasing the chance of a runway incursion.
