2007 Capacity Needs in the National Airspace System Report AIRPORT DATA SHEET

RESULTS: The analysis results for Los Angeles International Airport are listed below. Two future time periods were used (2015 and 2025). In

order to be identified in this study as an airport needing additional capacity, all four measurements must be met (represented by the red pie chart

segments below). The four measurements include: (1) ASV Ratio using the TAF; (2) ASV Ratio using the FATE forecast; (3) NAS-Wide Delay using

the TAF; and (4) NAS-Wide Delay using the FATE forecast. Definitions are provided on the attached page.

The intent of this study was to use a common set of criteria to assess the capacity of the National Airspace System as a whole, understanding that each

airport and metropolitan region is unique. The methodology used for FACT is not intended as a substitute for more detailed regional or airport specific

capacity studies. It is also recognized that some airports not identified in this study may still face capacity or other operational issues that will require

future airport enhancements.

Definitions

• An airport is capacity-constrained if it exceeds the ASV Ratio and NAS-Wide Delay

criteria for both TAF and FATE forecasts

• Annual Service Volume (ASV) metrics

- Annual Service Volume is the estimated annual traffic that equates to an average 7-minute

delay per operation.

- ASV Ratio is the ratio of forecasted demand to the ASV

• NAS-wide Delay metrics

- Annual Scheduled Arrival Delay is the forecasted average gate arrival delay at the airport

relative to the scheduled arrival time [measured in minutes]

- Arrival Queue Delay is the time that an aircraft has to wait to land due to operations by prior

arrivals [measured in minutes]

- Local Arrival Delay is the percentage of the modeled arrival delay that is due to delay at the

local airport rather than the origin/destination airport [measured in percent]

- Departure Queue Delay is the time that an aircraft has to wait to depart due to operations by

prior departures [measured in minutes]

• Annual Airport Capacity is an annualized traffic level based on the hourly Benchmark

capacities (or equivalent) for the airport

- Annual Airport Capacity is calculated by multiplying the hourly airport benchmark rates,

weighted by percentages for IMC and VMC occurrence, by the number of operational hours

(16 hours for OEP airports, 12 hours for non-OEP airports) for 365 days

INPUT The information listed below was used in this study for Los Angeles International Airport. The assumed airfield and ATC enhancements or

constraints for LAX are listed on the left. The tables on the right list LAX's calculated hourly capacity for three weather conditions in each of the three

study years (2007, 2015, and 2025).

'R

2015

Assumed Enhancements

Airfield: None

ATC: Improved threshold delivery accuracy

Assumed Constraints

Airfield: None -- sufficient taxiways and gates

ATC: None -- airspace accommodates all arrivals and departures

2025

Assumed Enhancements
