AVIATION & AERONAUTIC CALCULATOR
Speci Trigger
A precise tool.
What is the Speci Trigger & How does it work?
SPECI (Special Weather Report) is a type of aviation weather report that provides information on significant and urgent weather phenomena not included in the routine METAR reports. These reports are crucial for pilots to make informed decisions during their flights.
The issuance criteria for SPECI reports include changes in certain meteorological parameters such as temperature, dew point, wind speed and direction, visibility, altimeter setting, and significant weather phenomena. These changes must exceed predefined thresholds to trigger a SPECI report.
