SOCM-2 Seminar Data Link Advanced Operations Presented By: Dennis Addison, FAA Date: February 8, 2012
Oceanic Briefing Slide 2 KSFO Tailored Arrival (TA) Trials Initial TA Trials began in 2006 –Early Morning Traffic with little airport demand. –UAL aircraft only Latest TA Trials began December 2007 –Expanded beyond early morning flights –Refined arrival routing and renamed the arrival –Added additional operators –Reduced coordination requirements for controllers
Oceanic Briefing Slide 3 KSFO Tailored Arrival Profiles Determining the TA profile CREAN CINNY 3657N12335W AOB FL250 RAINS AOB FL200 PIRAT AOB 150 3722N12223W AOA 060 BRINY AOB 120 OSI MENLO AOA 040 Drawings not to scale KSFO MENLOOSI 3722/12223BRINYPIRAT RAINS3657/12335 CINNY CREAN Initial Altitude Descent Speed Winds Aircraft type
Oceanic Briefing Slide 4 Profile Development Goals Meet ATC requirements –Minimum IFR Altitudes –Noise Abatement –ATC Altitude Crossing Requirements Continuous Descent Idle Power Descent Keep aircraft within the expected descent profile.
Oceanic Briefing Slide 5 TAILORED ARRIVAL UPLINK A COMPLEX 4D TRAJECTORY PROFILE CLEARANCE IS UPLINKED TO THE AIRCRAFT FMS
Oceanic Briefing Slide 6 Tailored Arrival Route Clearance (169)(freetext) PACIFIC TWO TA Element One: Clearance Name
Oceanic Briefing Slide 7 Tailored Arrival Clearance Controller constructs the TA clearance using MOPS Element 83 Route Clearance
Oceanic Briefing Slide 9 Tailored Arrival Route Clearance (169)(freetext) PACIFIC TWO TA (83) AT COSTS CLEARED ROUTE (19) MAINTAIN F330 The clearance is constructed to clear the flight via the TA route and to maintain current altitude. The clearance is probed for conflicts and then sent to the aircraft.
Oceanic Briefing Slide 10 TAILORED ARRIVAL UPLINK Tailored Arrivals enable VNAV path to the Localizer. FMS determines most efficient aircraft descent profile
Oceanic Briefing Slide 11 TA Radar Vectoring/Routing The goal of the controller is to let the aircraft fly the TA without intervention, however at times it may be necessary to change an aircraft’s flight path. To do this, the controller must: –Issue a radar vector for traffic. –When the vector is complete or to shortcut an aircraft, the following instructions are issued: "Call Sign, cleared direct (waypoint on the TA) the remainder of the Pacific Two TA. Comply with Restrictions."
Oceanic Briefing Slide 12 Termination of Tailored Arrival At any time the Tailored Arrival may be terminated by the aircraft or ATC. If the flight crew replies “UNABLE” to any TA clearance, or requests cancellation of the TA, the TA is terminated for that flight. If the Tailored Arrival is terminated. – Advise the aircraft “Tailored Arrival is terminated”. Issue a new Route and Altitude clearance to the aircraft. Notify the downstream controller of OTA cancellation.
Oceanic Briefing Slide 13 Fuel Savings from Top of Descent Cruise to Landing Fuel consumption was calculated using the Boeing Climbout Program (BCOP) for low speed performance below 10,000 ft altitude. Fuel consumption above 10,000 ft altitude was calculated using the Boeing INFLT tool for cruise and descent. The vertical profile generated from BCOP and INFLT was matched to the mean descent paths of the collective ANOMS8 radar data. 777-200/GE90-85B747-400/PW4056 Full TA1,303 lbs2,291 lbs Partial TA 379 lbs1,100 lbs
Oceanic Briefing Slide 15 Dynamic Airborne Reroutes Allows Airborne Rerouting of Aircraft When Winds Indicate a More Fuel Efficient Route is Available Reduce Operating Costs by Taking Advantage of Updated Winds FANS and Air Traffic Services Inter-facility Data Communications (AIDC) Required Ongoing Trials in the South Pacific

Oceanic Briefing Slide 18 ADS-C CDP Clearances Procedure is based on in-trail Distance Measuring Equipment (DME) rules in ICAO Doc 4444, paragraph 126.96.36.199.2. *Near Simultaneous ADS-C Demand Reports *Climb/Descend an aircraft through the altitude of a blocking aircraft
