2. Overview Introduction (Obligatory Joke) AOSC Overview
A shepherd was herding his flock in a remote pasture when suddenly a brand-new Ferrari advanced out of a dust cloud towards him. The driver, a young man in a Prada suit, Gucci shoes, Dior sunglasses and D+G tie, leans out the window and asks the shepherd: "If I tell you exactly how many sheep you have in your flock, will you give me one?"
The shepherd looks at the man, obviously a yuppie, then looks at his peacefully grazing flock and calmly answers:  "Sure. Why not?"

Questions
The yuppie parks his car, whips out his Dell notebook computer, connects it to his AT&T cell phone, surfs to a NASA page on the internet, where he calls up a GPS satellite navigation system to get an exact fix on his location which he then feeds to another NASA satellite that scans the area in ultra-high-resolution mode. The young man then opens the digital photo in jpeg format to AutoCAD d and exports it to an image processing facility in Hamburg, Germany. Within seconds, he receives an on his Palm Pilot that the image has been processed and the data stored. He then accesses a MS-SQL database through an ODBC connected Excel spreadsheet with hundreds of complex formulae. He uploads all of this data via an on his Blackberry and, after a few minutes, receives a response. Finally, he prints out a full-color,150-page report on his miniaturized HP LaserJet, turns o the shepherd and says:  "You have exactly 1,586 sheep".
“That's right. Well, I guess you can take one of my sheep," says the shepherd.
He watches the young man select one of the animals and looks on amused as the young man stuffs it into the trunk of his car.   
Then the shepherd says to the young man:  "Hey, if I can tell you exactly what your business is, will you give me back my sheep?"
The young man thinks about it for a second and then says: "Okay, why not?".
"You're a consultant," says the shepherd.
"Wow! That's correct," says the yuppie. "But how did you guess that?"
"No guessing required," answers the shepherd. "You showed up here even though nobody called you, you want to get paid for an answer I already knew, to a question I never asked, and you know nothing about my business.
Now give me back my dog." The reason I like this story is it illustrates a point… no one knows your airport better than you!!!!

62.5:1 One Engine Inoperable (OEI) guidance

8. Decision Document 01 POFA and Runway Separation
POFA was renamed POFZ and included in Chg 8 to AC 150/ sent out September 30th, Same surface different name
New POFZ marking/signage standards became effective December (Standard ILS Signs)
FAA issued guidance for controllers to ensure POFZ is clear when weather is below 250 feet and ¾ mile and an aircraft is within 2 nautical miles final.
POFZ is required no later than January 2007

15. Decision Document #02 40:1 Departure Surface
Decision document #02 committed the Agency to…
Establish a consistent 40:1 OCS standard
Provide departure obstacle information to aircraft operators for all 40:1 penetrations
Revise both the internal coordination procedures and the policy criteria governing the circularization process in the OE/AAA program.
The 40:1 surface has been around for a long time for departures … the problem was how it was implemented was not consistent throughout the FAA DD 02 was implemented to correct this.
Basically it involved where the surface started. In some cases (TERPS) it started at departure end at threshold elevation … however if there was a penetration they could raise the surface up to a height of 35 feet above threshold elevation
OEAAA process always started the OIS at 35 feet. So obstacles were looked at differently.

16. Change 9 to AC 150/5300-13 Does not take effect until January 1,2008
Added a New Departure Surface :
Consistent with TERPS and FAR guidance
Added to Appendix 2
Applicable to all instrument runways with departure
procedures
Added a New One Engine In-Operable(OEI) Survey Surface:
Applicable at all runway ends used for air carrier departures
Surface to be included in the ALP and made available to all air carriers at the airport
Does not take effect until January 1,2008

17. Who knows your airport better than you??
AC 150/ Change 10
ARP will include 40:1 OCS clarification in change 10 of AC 150/
Departure Surfaces For Designated Runways
The applicability of the surface table A2-1 is dependant on the designation of primary runway(s) for departure. The Airport Sponsor through ARP to the RAPT, will identify runway end(s) intended primarily for instrument departures. The determination of primary runway(s) for departure does not prohibit or negate the use of other runways . It only identifies the applicability of the A2-1 surface to the runway end(s).
This is the new wording for Change 10
The key points are emphasized…
It is the airport sponsor’s responsibility to identify which runway(s) will be designated as the primary departure runways
Change 10 clarifies the criteria by not requiring every runway to be protected at 40:1 only those designated by the airport sponsor to the Regional/ADO office who will work with the RAPT to ensure appropriate choices are made based on ATC, Environmental, Airspace etc.
Who knows your airport better than you??
Remove, relocate or lower (or a combination of relocate and lower) the object to preclude penetration of applicable siting surfaces unless fixed by function and/or designated impracticable. Within 6000’ of the table A2-1 surface origin, objects less than or equal to an elevation determined by application of the formula in the criteria

18. 40:1 Departure Surface
No object should penetrate a surface beginning at the elevation of the runway at the DER or end of clearway and slopes at 40:1 . Penetrations by existing obstacles of 35 feet or less would not require TODA reduction or other mitigations found in the criteria - however, they may affect new or existing departure procedures.

19. OEI Departure Surface
Departure Runway Ends Supporting Air Carrier Operations.
Objects should be identified that penetrate a one-engine inoperative (OEI) obstacle identification surface (OIS) starting at the DER and at the elevation of the runway at that point, and slopes upward at a slope See figure A2-4.
Note: This surface is for provided for information only and does not take effect until January 1, 2008.

20. Action Plan ARP: Develop guidance consistent with this decision ATO:
Action Plan
ARP:
Develop guidance consistent with this decision
ATO:
Work with airports to develop operational guidance using existing infrastructure (e.g., outer taxiways)
AVS:
Provide guidance to supercede TIL A and emphasize that draft TIL has been withdrawn
Provide guidance to National Flight Procedures Group exempting the application of the above guidance during the bi-annual review process for existing procedures
Update and refine the Safety Assessment Toolset
Review standards based on updated toolset

21. Decision Document 04 Runway to Parallel Taxiway Separation
In support of Agency’s commitment to ensure safe precision approach and landing operations, policy clarification is needed, and the Airports Design A/C, TERPS and other guidance must be consistent (i.e., taxiing, parked and holding aircraft are obstacles)

22. Construction of New Runways/Parallel Taxiways
All CAT I operations
400 ft separation(500 ft for Group VI)
CAT II/III Operations
Groups I-IV aircraft ft separation
Group V aircraft ft separation*
Group VI aircraft ft separation*
*if Airport elects to proceed with construction

23. Existing Infrastructure
Existing Infrastructure
The Agency will work with airports to develop operational guidance where compliance can be achieved utilizing existing infrastructure without significant impact on airport efficiency.
Note that Airport improvement projects where a Draft Environmental Impact Statement was issued prior to approval of AOSC DD01 on December 18, 2003 will be treated as existing infrastructure.
