Definition
The specific set of weather information items — such as radar imagery, METARs, TAFs, AIRMETs, SIGMETs, winds aloft, PIREPs, and lightning data — that are transmitted to an aircraft in flight through a data link service like FIS-B (Flight Information Service-Broadcast) or a satellite-based subscription service. Each product is a distinct type of weather information, refreshed on its own schedule, and displayed in the cockpit on a multifunction display, tablet, or portable receiver.
Plain English
The individual pieces of weather information — radar pictures, airport weather reports, forecasts, wind data, and so on — that a pilot can receive in the cockpit through a wireless weather service.
Context Anchor
Seen in cockpit display menus, tablet weather apps, and FAA discussions of weather information received before or during flight.
Derivation
‘Data link’ means a wireless connection that carries digital information between the ground and the aircraft. ‘Products’ here is used in the information-services sense — each separate piece of output, like a radar image or a forecast, is one ‘product.’ Knowing this helps the pilot see that a data link weather service isn’t one big feed but a menu of separate items, each with its own update cycle and limitations.
Why Pilots Care
Provides timely weather information that helps pilots avoid hazardous conditions and make better in-flight decisions.
Intuition Check
“Products” are not pieces of equipment, and “data link” does not mean a perfect live view. Data Link Weather Products are prepared weather information sent electronically, and some items may be delayed or limited.
Example Sentence 1
Before descending into the area, the pilot reviewed several data link weather products, including the latest METAR and the regional radar image.
Example Sentence 2
Before departure, the flight crew reviewed the data link weather products for any significant weather along the planned route.
