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


Gps types of approaches
GPS: Types of Approaches

WAAS

BARO

IFR approved GPS


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


Ceiling minimum
Ceiling Minimum

14.9 mi2

9.9 mi2

2.1 mi2


Surveys obstacles
Surveys & Obstacles

  • Aeronautical Surveys

  • Accuracy Codes

  • Notification Process (7460)

  • Zoning Protection



Weather systems
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
Communication Systems

  • Direct

  • Remote Transmitter Receivers

  • Ground Communication Outlets

  • Phone / Void Time

  • Signs can help!



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
