Networked ATM for Efficient Routing, Phase I

Completed Technology Project

Project Introduction

Uncertainties in weather forecasts and traffic congestion sometimes result in inefficient planned flight paths for aircraft operating in the National Airspace System (NAS). Over the past several years, NASA developed two decision support tools to identify opportunities for efficient re-routes. The Dynamic Weather Routing (DWR) system uses information generated on the ground to identify candidate flights for re-routing and the airline operations center (AOC) sends the proposed change to the flight deck for subsequent negotiation with air traffic control (ATC). The Traffic Aware Strategic Aircrew Requests (TASAR) system is flight deck-based, using information available on the aircraft and software in the electronic flight bag (EFB) to suggest alternative routes. DWR successfully completed operational tests at ZFW and American Airlines and TASAR will soon begin operational evaluations at Alaska Airlines and Virgin America. Our concept proposes a more capable architecture that can take full advantage of emerging communications technologies to integrate AOC and flight deck capabilities. This approach offers a more robust, extensible architecture that can be tailored to an individual airline's operational model while simultaneously offering an upgrade path for adding more capability over time. Our solution aims to combine the best features of DWR and TASAR and adds more capability via enhanced data communications. Our solution fully integrates with the AOC but retains full access to the superior information from the flight deck. This enables our architecture to use the best available data, allocate data processing and analytical functions to where they can be performed most efficiently, and allows the airline to choose where it wants decision making to occur.
