1 Obstruction Evaluation 2015 GDOT PowerPoint GAA Title Spring Page Conference What are all these surfaces? February 19, 2016 Sub Titles Presented By Alan Hood, Airport Safety Body Text Data Program Manager Georgia DOT

2 Approach Surfaces and Obstruction Removal Categories of approach surfaces for GA Airports. State Licensing FAA Part 77 FAA TERPs Visual Surface (20:1)

3 GDOT Airport Licensing Approach Standards State Licensing 3 configurations - based on runway length < 4,000 4,000 4,999 5,000 + Meets visual approach criteria from design guide Surface starts at threshold Surface needs to be clear to meet the minimum state licensing criteria Generally least restrictive of the three surfaces Airports inspected biennially

4 GDOT Airport Licensing Approach Standards 20:1 15:1 20:1 700 To 5000 To 10,000 To < >5000

5 GDOT Airport Licensing Approach Standards Obstruction Removal obstructions should be removed immediately or removal efforts should be initiated as soon as possible with written plan provided to GDOT by specified date in letter. if removal is not possible, displace threshold Documentation of obstructions: biennial inspection letter Notification Alan Hood, Airport Safety Data Program Manager and GDOT Project Manager

6 FAA Part 77 Approach Standards Generally most restrictive, used as screening criteria 9 configurations: Based on runway category and type of approach <12,500lb - visual = A(V) <12,500lb - visual - opposite A(NP) = A(V) op A(NP) <12,500lb - non-precision = A(NP) >12,500lb - visual = B(V) >12,500lb - visual - opposite D/PIR = B(V) op D/PIR >12,500lb - > ¾ mi visibility = C >12,500lb - > ¾ mi visibility - opposite D/PIR = C op D/PIR >12,500lb - < ¾ mi visibility = D >12,500lb - precision = PIR Surface starts 200 from the end of the runway Surface should be clear to meet FAA 5010 Safety Data Inspection Program criteria Airports inspected biennially

7 FAA Part 77 Approach Standards 10,000 40,000 50:1 34:1 34:1 5,000 20:1 20:1 20: A(V) 32 B(V) 32 A(NP) 32 C 32 D 32 PIR

8 FAA Part 77 Approach Standards Obstruction Removal Obstructions should be removed or provide schedule for removal Documentation of obstructions: biennial inspection letter FAA 5010 report Notification Required Provide sketch and coordinates of cleared area Alan Hood, Airport Safety Data Program Manager and GDOT Project Manager GDOT will coordinate with FAA to remove from FAA database

9 Who is Responsible? Ultimately the Sponsor -State Licensing and Part 77 Inspections: When obstructions are identified in an inspection, they become a liability. -State Licensing surface obstructions could lead to denial of license.

10 FAA TERPs Visual Surface Standards (20:1) Surface starts 200 from threshold 20:1 Approach Slope Obstructions should be mitigated to maintain night minimums When are procedures reviewed? Any request for change in approach, name change, LOC-ID change, runway numeral change, etc FAA performs review of airport s terminal procedures every 2 years

11 FAA TERPs Visual Surface Standards (20:1) 20:1 Surface for Categories 20:1 A D are all same size 34:1 now 20: A(NP) 32 C

12 FAA TERPs Visual Surface Standards (20:1) Obstruction Removal mitigate obstructions by: removal lighting PAPI waiver requires FAA Flight Standards approval obstructions should be mitigated to maintain nighttime procedures. Obstruction removal previous to 20:1 letter from Flight Procedures. Sketch and coordinates of cleared area Alan Hood, Airport Safety Data Program Manager and GDOT Project Manager GDOT notifies FAA to update database

13 FAA TERPs Visual Surface Standards (20:1)

14 Who is Responsible? Ultimately the Sponsor -Sponsors are also responsible for ensuring the TERPs Visual Surface is clear. Flight Procedures uses the FAA surveyed obstruction database to review procedures. -Obstructions do not automatically disappear from database with a new survey. -Must submit sketch with coordinates and boundaries of cleared areas to get obstructions removed from database. ***If you have been notified you have obstructions by Flight Procedures then you validate the obstructions in writing. No survey or coordinates and boundaries required unless you are topping obstructions.
