What is SPECI in aviation terms?

In aviation terminology, a SPECI is specifically a special weather report that is issued when there are significant changes in weather conditions at an airport or within a specific area. This report is crucial for flight operations as it provides updated information that can affect takeoff, landing, and overall flight safety.

SPECI reports are issued between routine reports, known as METARs, and include changes in weather phenomena such as wind shifts, visibility reductions, or significant changes in precipitation. The goal of issuing a SPECI is to ensure that pilots and air traffic controllers have the most current and relevant weather information to make informed decisions regarding flight operations.

A routine weather report is different as it does not reflect real-time significant changes, and a special report post-flight does not exist in standard aviation practices. Additionally, standard communication for emergency situations refers to different protocols and does not specifically relate to weather reporting. Hence, recognizing the purpose and context of a SPECI reinforces its importance in maintaining situational awareness in aviation.
