Terminal Area Weather

Providing accurate, timely weather information to aviation decision makers

If poorly predicted, local weather phenomena can bring operations in an airport terminal area to a standstill. The problem spans definitions of hazardous weather, through detection and short–term forecasts, through effective dissemination and communication of those hazards. RAL has considerable experience in these areas, and has fielded systems which assist air traffic controllers and ground operations staff to prevent unnecessary delays.

One aspect of these systems is the incorporation of user input for display design. Specific users need specific formats that they are used to seeing and reacting to – and these formats are determined during the development phase of any project. Timing is important since even the most accurate information delivered too late is not effective.

RAL's systems for Terminal Area Weather have included the Terminal Doppler Weather Radar (TDWR) Program, the Low Level Wind Shear (LLWS) System, The Weather Support for Deicing Decision Making (WSDDM), the Taiwan Advanced Operational Aviation Weather System (AOAWS), the Terminal Area Surveillance System (TASS), and the Juneau Wind Alarm System (JAWS). As opportunities present themselves RAL will continue to develop end–to–end weather systems to aid smooth terminal operations.
