Virginia System Study Facilities & Equipment / NAVAIDs presented by: Delta Airport Consultants, Inc. March 4, 2009
What is an Instrument Approach Procedure? • Safe, efficient transition from up there to down here • Adverse weather accessibility runway
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
GPS: Disruptive Technology! • A good great, wonderful thing! • A paradigm shift • Like the internet has been to travel
GPS: Types of Approaches WAAS BARO IFR approved GPS
The Role of Minimums • Comprised of: • Aircraft Category • Ceiling minimum • Visibility minimum • Why is lower better?
Visibility Minimum • Visibility is the Governing Number! • Type of Procedure • Airfield Facilities • Approach Lights • Runway Visual Range vs. Prevailing Visibility
Ceiling Minimum 14.9 mi2 9.9 mi2 2.1 mi2
Surveys & Obstacles • Aeronautical Surveys • Accuracy Codes • Notification Process (7460) • Zoning Protection
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
Communication Systems • Direct • Remote Transmitter Receivers • Ground Communication Outlets • Phone / Void Time • Signs can help!
Study Elements • Inventory / GIS Development • System View • Airport-Specific Recommendations • Airport IQ Integration • Review of Future Developments • Implementation Plan
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
How this Applies to Your Airport • Inventory What You Have • Set Goals • Make Small Adjustments • Plan for Big Improvements
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
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
