  1. Virginia System Study Facilities & Equipment / NAVAIDs presented by: Delta Airport Consultants, Inc. March 4, 2009

  2. A Mile Of Runway ….

  3. What is an Instrument Approach Procedure? • Safe, efficient transition from up there to down here • Adverse weather accessibility runway

  4. Vocabulary: Types of IAPs

  5. Safety Record • Radar vs. Non-Radar • Accident risk without terminal radar … 3.1 times higher than with terminal approach radar • Precision vs. Nonprecision • Accident risk of non-precision approaches … 5.2 times higher than precision approaches … • Circle-to-Land

  6. GPS: Disruptive Technology! • A good great, wonderful thing! • A paradigm shift • Like the internet has been to travel

  7. GPS: Types of Approaches WAAS BARO IFR approved GPS

  8. The Role of Minimums • Comprised of: • Aircraft Category • Ceiling minimum • Visibility minimum • Why is lower better?

  9. Visibility Minimum • Visibility is the Governing Number! • Type of Procedure • Airfield Facilities • Approach Lights • Runway Visual Range vs. Prevailing Visibility

  10. Ceiling Minimum 14.9 mi2 9.9 mi2 2.1 mi2

  11. Surveys & Obstacles • Aeronautical Surveys • Accuracy Codes • Notification Process (7460) • Zoning Protection

  12. Beyond Type & Minimums

  13. Weather Systems • Needed: LOCAL Weather • Remote Altimeter Setting Source? Penalty! • Types of Systems • ASOS or AWOS III (Part 91 and Part 135) • AWOS A (Part 91) • Additional AWOS Sensors • NADIN

  14. Communication Systems • Direct • Remote Transmitter Receivers • Ground Communication Outlets • Phone / Void Time • Signs can help!

  15. Virginia System Study

  16. Study Elements • Inventory / GIS Development • System View • Airport-Specific Recommendations • Airport IQ Integration • Review of Future Developments • Implementation Plan

  17. What We Found • Only 11 LPV approaches in the system (excluding DCA & IAD) • 9 of the ILS approaches are non-standard • 5 of the 8 relievers require circle-to-land • 17 airports with altimeter adjustments

  18. System Goals

  19. How this Applies to Your Airport • Inventory What You Have • Set Goals • Make Small Adjustments • Plan for Big Improvements

  20. What Can You Do Today? • Know Your Procedures • Minimize Accuracy Code Adjustments • Commission Aeronautical Surveys • Address Close-In Obstructions • Request Improvements • Eliminate Circle-to-Land • Eliminate Non-Standard Minimums • Optimize Communications • Optimize Weather Reporting

  21. What We Didn’t Talk About • Airport Infrastructure • AC 150/5300-13, guidance in chapters • AC 150/5300-13, guidance in appendix • FAR Part 77

  22. Put your head in the clouds!
