One Engine Inoperative (OEI) Description
• Air Carriers are required to clear obstacles in
one-engine out departure situation
• Each carrier maintains their own chart of
critical obstacle height & locations
• Each carrier computes a 35 ft. obstacle
clearance based on specific aircraft load and
performance – given reduced climb gradient
• FAA historically only protected for instrument
approach procedures
• There are known impacts to departure
payload due to obstacles in departure area

An Airport Obstruction Standards
Committee (AOSC) Initiative
• AOSC formed in 2003 by FAA Administrator
charter
• Addresses cross lines-of-business (LOB)
issues on:
– FAA policy
– Airports and airspace
• Steering Group and Working Group answerable

Challenges
Define “off the end of each commercial
runway that requires an OEI procedure” for:
• Straight obstacle Identification area
• Turning obstacle Identification area
• Surface gradient for each area
• Extent of flexibility and enforcement of
defined areas

OEI Pilot Project - Airports
• FAA Administrator/OEI focus
- Look at an airport community-centered solution
- Consolidate FAA policies within the LOBs
- No modifications to applicable rules
• Pilot project airports OEI issues:
-
OEI flight routes over residential areas (BOS, MIA, PHX)
Complicated zoning issues (BOS, PHX, LAS)
Complicated air traffic operations (DCA, PHX, LAS)
Complex terrain surrounding airport (PHX, LAS)
Complex and dense Special Use Airspace (DCA, LAS)

Recommendations of the OEI Pilot Project
• Single OEI area will not suit all Airports/Users
– Straight and turning
– 50:1 versus 62.5:1
• Harmonization with ICAO standards, to extent
possible
• Extent of flexibility and enforcement for the
defined areas – Something with “TEETH”
• Grandfathering requirements versus new
development

Discussion/Recommendation - OEI OIS Area
Departure runway ends supporting air carrier operations. Objects
should be identified that penetrate OEI OIS starting at DER.
Straight
Left turn?

Recommended Flexibility & Enforcement
FAA is attempting to establish the right amount of
flexibility in guidance for OEI Surface Areas and
Slopes:
Strict Implementation:
–
–
–
–
Single surface
No penetrations
No grandfathering
Immediate removal of all
obstacles that penetrate
that surface
Easy to enforce,
impossible to implement

Flexible Implementation:
– Multiple self-defined
surfaces
– Penetrations not a factor
– Excessive grandfathering
– No removal of penetrations
– Develop Area and Slope as
desired
Impossible to enforce,
easy to implement

Next Steps
• The FAA plans to issue notice in the Federal Register of
proposed policy statement on OEI and may potentially
include;
– Intention of the FAA to implement the pilot program recommendations
– Impact to the airport may be measured in reduction of passengers, fuel, cargo
• Proposed implementation timeline once the policy is finalized:
– FAA to develop detailed policy and guidance (approx. 12 months)
– Work with the 5 pilot airports to develop OEI tracks (approx. 24 months)
– Work with additional airports to develop OEI tracks (approx. 36 months)
– Dependent on funding available
