Juneau Terrain Induced Turbulence Project: Non-FAR Part 121 User Needs Summary Report

摘要

Juneau International Airport (PAJN), Alaska, has a combination of extreme terrain features and adverse weather patterns that creates moderate to severe Terrain Induced Turbulence. As a result of this turbulence, the Federal Aviation Administration (FAA) has funded the National Center for Atmospheric Research (NCAR) to develop a Wind Hazard Information System (WHIS) for use by aviation users. This report describes the user needs assessment of the Juneau Terrain Induced Turbulence Project by ACT-320. Current practices were baselined and wind information needs were identified and defined for Non-FAR Part 121 Pilots, Automated Flight Service Station (AFSS) Specialists, Air Traffic Control Tower (ATCT) Specialists, and National Weather Service (NWS) Forecasters. Surveys and on-site interviews were used to gather information. In general, wind information used by the above mentioned users was not timely. The Gastineau Channel, Taku Inlet area, Outer Point, and PAJN were identified as being most impacted by winds. The importance of wind information varied across user groups.
