Runway Incursion Prevention Airport Design – AC 150/5300 Change - 17

1. Runway Incursion PreventionAirport Design – AC 150/5300Change - 17 <Audience> Presented to: Eastern Region Annual Airport Conference Hershey Conference By: Khalil E. Kodsi, P.E. PMP Date: April 4, 2012 <Date>

2. Runway Safety Objective Minimize the likelihood of Runway Incursions: • Improve taxiway geometry • Increase situational awareness • Improve Operational use of taxiways

3. Increase Situational Awareness • FAA Engineering Brief No. 75 • Incorporation of Runway Incursion Prevention into Taxiway and Apron Design – 11/08/07 • http://www.faa.gov/airports/engineering/engineering_briefs/ • Change 17 to FAA AC 150/5300-13, “Airport Design” • Improve Taxiway Geometry: • “3 – Node” taxiway intersection • Taxiway/ Runway interface • Entrance Taxiways

4. “3-Node” Intersection • Multiple intersecting angles of: • 30, 45, 90 degrees from the traveling taxiway • Optimize fillet designs • Bring airfield signage closer • “Right Angle” entrance taxiway - best visual perspective • View aircraft traffic in both directions • Optimum pilot orientation for viewing taxiway signage

5. Standard Intersection Details Avoid This!

6. Taxiway / Runway - Interface Avoid This! • Optimum design is right-angle • No less than 45 degrees • Exception for High Speed Exits • Not Recommended: • Y-shaped taxiway crossing • Taxiway crossing a High Speed exit • Taxiway connecting to V-shaped runways • Aligned taxiway (Prohibited) • Direct access from a ramp/ terminal to the runway • High-speed exits leading directly onto another runway

10. Entrance Taxiway • Avoid wide expanses beyond taxiway design tables • Islands provide location for elevated signage • Standard orientation is 90 degrees • Standard length to accommodate longest fuselage • Curve “outer-edge” to mitigate wrong runway landing

11. Hot Spots

12. Improve Taxiway Operational Use • Avoid using runways as taxiways • Use taxiing strategies to reduce active runway crossing • Correct runway incursion “Hot Spots”

13. Change – 17 (Highlights) • Taxiway Dimensional Standards – Group VI: (taxiway wonder study – EB80 ) • Taxiway width is reduced from 100 feet to 82 feet • Taxiway edge safety margin is reduced from 20 feet to 15 feet • Computer Program. Appendix-11 has been deleted including all references throughout AC. • “Wind Rose” analysis tool has been added to Airport GIS website • Appendix – 16 “New Instrument Approach Procedures” • Changes in tables and footnotes to clarify requirements based on Appendix 2 (TERP) • The use of OFZ criteria as the basis to justify a reduction in runway to taxiway separation standards is not allowed. • Taxiway geometry enhancement to minimize Runway Incursions. • Appendix 15, Transfer of Electronic Data - Deleted. Guidance has been superseded by Airports GIS. • Chapter 4, Table 4-2: Deleted lower section of table dealing with judgmental oversteering.
