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

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

3. 3 Federal Aviation Administration 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. 4 Federal Aviation Administration 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. 5 Federal Aviation Administration 5 Standard Intersection Details Avoid This!

6. 6 Federal Aviation Administration 6 Taxiway / Runway - Interface 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 Avoid This!

10. 10 Federal Aviation Administration 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. 11 Federal Aviation Administration Hot Spots 11

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

13. 13 Federal Aviation Administration 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.
