## 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 inthis study as an airport needing additional capacity, all four measurements must be met (represented bythe 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.

Themethodology used forFACTis notintended asasubstitute formore detailed regional orairport specific capacity studies. Itis also recognized thatsome airports notidentified in this study maystill face capacity orother operational issues that willrequire 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 isthe 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 isthe 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, bythe 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 inthis study for Los Angeles International Airport. The assumed airfield and ATC enhancements or constraints for LAX are listed on the left. The tables onthe right list LAX's calculated hourly capacity for three weather conditions in each of the three study years (2007, 2015, and 2025).
