IFR Criteria and Your Airport Goals:

IFR Criteria and Your AirportGoals

1. Quick review of criteria changes.
2. Airport Managers role in gaining the best IFR
   minimums.
3. Survey and data requirements.

FAA Contacts

• IFR procedures Boston Flight Procedures
  Office/Sue Crumb [phone]
• Airport Design Criteria Airport Division/ (781)
  238-7600
• Operational Safety/Criteria Flight
  Standards/Gerry Holtorf [phone]

3
Why All the Change?

• International concern over Controlled Flight Into
  Terrain (CFIT).
• Vertical guidance key to fewer accidents.
• Resulted in the FAA changing instrument procedure
  criteria (TERPS).
• TERPS Change 17 (1998) and 18 (1999).
• TERPS and airport Advisory Circular 150/5300-13
  now better aligned.
• A visual area assessment is required.

4
Visual Area Assessment for IFR Procedures

• Flight Standards 10/07/03 policy letter.
• Apply paragraph 251
• For all new approach procedures
• For existing, when amended or reviewed

5
What if VAAR is penetrated?

• Flight Procedures will notify airport manager.
• From date of notification, 3 years to address
• Reduce height/ clear obstructions, or
• Mark/light obstruction(s).

6
If clearing or lighting cant be done?

• 201 penetrations may be mitigated by
• A vertical glide slope indicator (VGSI).
• Sited at or above 3.0 degrees.
• VGSI obstacle surface must be clear.
• Note on approach plate requiring VGSI for night.

7
What will these changes mean to my airport?

• NEW APPROACH airport design standards are
  integral to gaining a new approach. Advisory
  Circular 150/5300-13 is now better aligned with
  TERPS.
• EXISTING IFR APPROACH Obstruction penetrations
  of these visual assessment surfaces may cause a
  change to straight-in or night circling minimums.

8
If this three years catches up to you

• FAA will take steps to not authorize night
  minimums to the affected runways.
• UNLESS
• Acceptable corrective action is in progress, and
• Airport submits a request for extension.

9
Airport Managers Role

• Initiate an Aeronautical Study
• 1. Airport sponsor initiates the request.
• 2. Master Plan or Airport Layout Plan (ALP)
  considerations.
• 3. Requirements identified for data, survey,
  environmental, etc.
• 4. Determine funding and plan of action.
• FAA completes the Aeronautical Study.

10
Remember

• Survey Level of obstruction survey depends upon
  level of approach minimums desired.
• Data accurate runway ends, navigation/ visual
  aid site info up to date ALP and 5010.
• Communication with the Flight Procedures Office
  and Airports Division.
• NOTE Lead times for procedures can exceed
• ONE YEAR!

11
SurveysIn accordance with FAA Specification
405 Requirements provided in Appendix 16 of
AC 5300-13No survey day/visibility equal to
or gt1smPart 77 Level C or D Non-precision

13
How do I know what applies?

• Check AC 150/5300-13 Appendix 16.
• Provides a matrix of minimums vs. airport
  requirements.
• Generally in concert with TERPS.
• Are the runway OFZ and safety area correct for
  largest design group aircraft?
• TERPS minimums now effected by OFZ, hold lines,
  etc.

14
Circling Approaches

• Require visual assessment for night approach
  minimums.
• Smaller area than for straight-in nonprecision
  approaches.

15
Straight-in Approaches

• Require visual assessment for day and night
  approach minimums.
• Generally larger than circling area.
• Slope varies depending upon visibility.

16
SUMMARY

• New Procedures
• Process generally starts with the Airports
  Division
• ALP revision
• Contact your ANE-600 planning person
• Request the procedure through the FPO/Sue Crumb
• -Sue Crumb [phone]
• Plan to work with FAA team through an iterative
  aeronautical study process.

17
Summary Cont.

• Existing Procedure Assessments
• Dont wait for FAA to come knocking
• Plan ahead.
• Get the evaluation process started.
• Request an Aeronautical study if required.
• We want to protect the maximum utility of your
  instrument approaches.

18
OK! Whats the bottom line?

• FAA will work together with you and your staff
  and/or consultants during the Aeronautical Study.
• Evaluate Part 77 penetrations.
• Study of applicable Airport Design AC TERPS
  surfaces.
• Good Part 77 survey supports most of the approach
  analysis (some exceptions).
• Examine lowest minimums possible.
• FAA determination includes Part 77 obstruction
  lighting if clearing not practical.
