Overview of the Juneau terrain-induced turbulence and windshear project

The area around the Juneau International Airport is dominated by mountainous terrain and often experiences strong winds. Aircraft have encountered significant windshear and turbulence while performing the unique approach and departure procedures necessary to avoid the nearby terrain. The Juneau terrain- induced turbulence and windshear project was undertaken by the Federal Aviation Administration and the National Center for Atmospheric Research to research and develop a warning system that can alert pilots of hazardous turbulence and windshear conditions in Juneau. An overview of the project's hazard detection algorithm approach, data collection, alert scheme, and performance will be discussed. Additional related papers will cover specific aspects of the project in greater detail.
