Analytical Workload Model for Estimating En Route Sector Capacity in Convective Weather
نویسندگان
چکیده
We have extended an analytical workload model for estimating en route sector capacity to include the impact of convective weather. We use historical weather avoidance data to characterize weather blockage, which affects the sector workload in three ways: (1) Increase in the conflict resolution task rate via reduction in available airspace, (2) increase in the recurring task load through the rerouting of aircraft around weather, and (3) increase in the inter-sector coordination rate via reduction in the mean sector transit time. Application of the extended model to observed and forecast data shows promise for future use in network flow models. Keywords-air traffic management; sector capacity; workload model; convective weather

Sector Workload Model for Benefits Analysis and Convective Weather Capacity Prediction
En route sector capacity is determined mainly by controller workload. The operational capacity model used by the Federal Aviation Administration (FAA) provides traffic alert thresholds based entirely on hand-off workload. Its estimates are accurate for most sectors. However, it tends to over-estimate capacity in both small and large sectors because it does not account for conflicts and recurrin...
متن کاملMacroscopic Workload Model for Estimating En Route Sector Capacity
Under ideal weather conditions, each en route sector in an air traffic management (ATM) system has a certain maximum operational traffic density that its controller team can safely handle with nominal traffic flow. We call this the design capacity of the sector. Bad weather and altered flow often reduce sector capacity by increasing controller workload. We refer to sector capacity that is reduc...

A major concern in contemporary traffic flow management (TFM) is improving decision making when severe convective weather (Wx) impacts en route sectors throughout the National Airspace System (NAS). The FAA is currently seeking to reduce these convective weather delays through the use of multi-hour (e.g. 4 and 6 hour) Wx forecasts coupled with strategic planning by the FAA traffic flow managers...
متن کاملModel Estimates of Traffic Reduction in Storm Impacted En Route Airspace
An understanding of convective weather impacts on en route airspace capacity is a first step toward development of predictive tools to support both tactical and strategic routing decisions in storm-impacted airspace. This study presents a model for traffic reductions in en route sectors that result from convective weather impacts. A model to predict the impact of convective weather on en route ...
متن کامل[EN-012] Validation of En Route Capacity Model with Peak Counts from the US National Airspace System
Airspace capacity estimates are important for managing air traffic and predicting the effectiveness of new airspace designs and proposed decision support tools. Because air traffic management relies on manual procedures, controller workload determines the traffic limit of most sectors. Current operational procedures for estimating capacity in United States airspace do not account for conflict a...
