  • FAA AIRE Initiatives

    • Oceanic Optimization Trials

    • Gate to Gate

    • Surface Optimization

    • Continuous Descent Operations (CDO)

      • Optimized Profile Descent (OPD)

      • Tailored Arrivals (TA)

Continuous descent operations cdo

Continuous Descent Operations (CDO)

  • CDO

    • An operation, enabled by airspace design, procedure design and ATC facilitation, in which an arriving aircraft descends continuously, to the greatest possible extent, by employing minimum engine thrust, ideally in a low drag configuration, prior to the final approach fix /final approach point

      (ICAO Doc 9931)

  • Optimized profile descent (OPD)

    • OPD is one method of facilitating CDO. The OPD is a descent profile normally associated with a published arrival (STAR) and designed to allow maximum practical use of a CDO. It starts from top of descent, taking into consideration the limitations of local airport, airspace, environmental, traffic, aircraft capabilities, and ATC.

  • Tailored Arrival (TA)

    • Tailored Arrivals (TAs) are fuel efficient, environmentally friendly arrival clearances delivered to the aircraft via data link

Faa opd initiatives

FAA OPD Initiatives

  • Los Angeles Airport (LAX)

    • The first published, publicly-available OPD procedure in the United States, the River One STAR, was implemented at Los Angeles Airport (LAX) in 2007

    • Data analyzed for mixed-fleet arrival operations each year indicate that we achieve average fuel savings of 25 gallons per flight and reduce the average level-flight time during approaches by 26 percent for approximately 300-400 daily LAX OPD arrivals

    • With approximately 545,000 operations in 2009, LAX is the fifth busiest airport in the NAS

    • An estimated 40% to 50% of the approaches into LAX are now OPDs

Faa opd initiatives1

FAA OPD Initiatives

  • Miami (MIA) and Atlanta (ATL) International Airports

    • Twenty OPDs were completed in May 2008 at Miami and Atlanta International Airports

    • Computed fuel savings averaged 48-52 gals/flight, with a corresponding per-flight reduction of 1050-1090 lbs CO2

    • Later the same year, 2008, OPD procedures saved 40-60 gallons of fuel and avoided more than 800 pounds of carbon emissions per flight in 600 night-time OPD arrivals into ATL

  • Honolulu (HNL) and Anchorage (ANC) International Airports

    • HNL OPD projected fuel savings 4.3 million gallons/yr ;84 million lbs/CO2/yr

    • ANC OPD projected 4.2 million gallons/yr fuel savings; 83 million lbs CO2/yr

Faa opd initiatives2

FAA OPD Initiatives

  • Charleston International Airport (CHS)/Charleston Air Force Base

    • In 2008, the Department of Defense (DOD) and the FAA initiated a joint initiative to evaluate the use of OPD arrivals for the Air Force C-17 transports at CHS

    • An RNAV Implementation Working Group was established in accordance with FAA Order 7100.9D, Guidelines for Implementing Terminal RNAV Procedures, commonly known as the “18-Step Process”

    • Eight (draft) RNAV STARS developed, six with OPD vertical profiles

    • Delta Airlines is commercial lead operator for these procedures. US Airlines and Southwest Airlines have joined the CHS RNAV Implementation WG

    • Publish date for public use CHS OPD procedures is scheduled for August 2011

Tailored arrivals ta history

Tailored Arrivals (TA) - History

  • The first TAs are designated Tailored Arrivals (TA)

  • The TA is a pre-planned, fixed routes received via data link from ATC’s Ocean21 system to Future Air Navigation Systems (FANS-1/A) equipped aircraft

  • Ocean21 is the only automated ATC system in the United States capable of data link; therefore, TA clearances can only be issued from New York Center (ZNY), Oakland Center (ZOA), or Anchorage Center (ZAN) where Ocean21 is operational

  • TA clearances are only issued upon pilot request

  • FAA TA development began during flight trials conducted at San Francisco (SFO), Los Angeles (LAX), Miami (MIA)

Tailored arrivals ta

Tailored Arrivals (TA)

  • TA consists of three elements

    • TA clearances issued by ATC through the Ocean21 system via data link to FANS 1/A equipped aircraft

    • A TA consists of a lateral, vertical and speed profile, and connection to a published instrument approach from the aircraft's navigation database.

  • Pilots fly the TA according to the operator’s standard operating procedures (SOP)

Tailored arrivals ta results

Tailored Arrivals (TA) Results

  • Overall Statistics, All Trial Sites:

    • 1469 Full Tailored Arrivals

    • 3411 Partial Tailored Arrivals

  • SFO: (from start in Dec 2007 to Aug 2010)

    • 33% (1203) of flights requesting have gotten full TAs

    • 67% (2407) of flights requesting have gotten partial TAs

  • MIA: (from start in June 2009 to October 2010)

    • 17% (24) of clearances request result in full TAs

    • 83% (117) of clearances request result in partial TAs

  • LAX: (from start in Nov 2009 to November 2010)

    • 22% (242) of clearances sent receive full TAs

    • 78% (877) of clearances sent receive partial TAs
