what is an instrument approach procedure
What is an Instrument Approach Procedure?
  • Safe, efficient transition from up there to down here
  • Adverse weather accessibility

runway

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

the role of minimums
The Role of Minimums
  • Comprised of:
    • Aircraft Category
    • Ceiling minimum
    • Visibility minimum
  • Why is lower better?
visibility minimum
Visibility Minimum
  • Visibility is the Governing Number!
  • Type of Procedure
  • Airfield Facilities
      • Approach Lights
      • Runway Visual Range vs. Prevailing Visibility

study elements
Study Elements
  • Inventory / GIS Development
  • System View
  • Airport-Specific Recommendations
  • Airport IQ Integration
  • Review of Future Developments
  • Implementation Plan
what we found
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
How this Applies to Your Airport
  • Inventory What You Have
  • Set Goals
  • Make Small Adjustments
  • Plan for Big Improvements
what can you do today
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
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
