Tailored Arrival Environmental Criterion 1. Data analysis included Tailored Arrivals flight candidates ANA8, ANZ8, JAL2, JAL880, QFA73, SIA16, UAL (1404, 34, 72, 74, 76, 78, 830, 838, 852, 856, 856D, 858, 862, 870, 872, 886, 888, 892, 9816, 9822) Flights that arrived via Woodside (OSI) or Point Reyes (PYE) 2. Primary data source: radar data from the SFO ANOMS8 system 6 days (1/03/08, 1/24/08-1/26/08, 2/23/08 and 11/01/08) were missing due to ANOMS8 outages 3. Flights sorted by Tailored Arrivals sort criteria using ATS clearances and ADS-C reports Analysis of ANOMS8 radar data to verify and refine the initial sorting 4. Fuel consumption calculations: For low speed performance below 10,000 ft altitude, using the Boeing Climbout Program (BCOP) Above 10,000 ft altitude, using the Boeing INFLT tool for cruise & descent. Vertical profile generated from BCOP and INFLT was matched to the mean descent paths of the collective ANOMS8 radar data Common start point at cruise EOT_RT_Sub_Template.ppt 2
Tailored Arrival Environmental Criterion, Cont. 5. Tailored Arrivals (TA) sort criteria, using ATS clearances and ADS-C data Non participating - Opted out of procedure or were ineligible Note: As ineligible flights are included in the above statistics, numbers should not be interpreted as pilot participation in Tailored Arrivals Partial Tailored Arrival Met SOME of the TA criteria Full Tailored Arrival Met ALL of the TA criteria 6. Environmental Criterion: Radar data shows no more than ONE Level Flight Segment and that is no more than ½ Nmi. 7. Evaluated all the ANOMS8 data to check if met Environmental Criterion including Non-Tailored Arrivals. EOT_RT_Sub_Template.ppt 3
