Sheffield flight dispatcher school reports on the FAA’s change to the Enhanced Weather Information Systems (EWINS). The regulatory changes are impacting the operator options in terms of obtaining weather data and forecasts. Operators in these categories must now use government sources or repackaged government weather data and forecasts, or they must take very specific steps to approve the use of third-party, tailored weather data and forecast providers. Here is what the aircraft dispatcher certifiers want you to know.
1. Federal Aviation Administration regulatory changes have already gone into effect.
The change mandates that operators use government sources for weather data or request and obtain specific approval to use a Commercial Weather Information Provider (CWIP). You must set up an Enhanced Weather Information System at your location and be approved.
Automatically approved weather sources include:
- North Atlantic Treaty Organization (NATO) military observations
- International Civil Aviation Organization (ICAO) or World Meteorological Organization (WMO) operated meteorological offices
2. These changes to the regulations does not affect all EWINS operators.
The FAA regulatory changes only affect Part 135, 91K and 121 operations of N-registered aircraft.
3. Approval is mandatory to use tailored or customized commercial weather forecasts.
Approval is necessary for the creation of a Terminal Aerodrome Forecast (TAFs) and weather charts, and then must be added to the Ops Specs of the flight department.
4. Be aware of you best weather options.
A customized/tailored approach to weather and weather forecasts can provide added value service for EWINS operators than just providing repackaged government source weather data and forecasts.
5. Commercial weather providers offers additional advantages.
Having consultations with local meteorologists with additional experience will allow aircraft dispatchers to obtain a better picture of the local weather, which will provide the crew with more knowledge to make more informed decisions.
