How many sections does a SPECI observation contain?

A SPECI observation report is a type of aviation weather report that provides updates to the standard METAR report. It consists of specific segments that are crucial for conveying weather changes efficiently.

The correct answer highlights that a SPECI observation contains two main components: the body of the report and the remarks. The body of the report includes essential weather data such as temperature, dew point, wind direction, visibility, and significant weather phenomena. This information is vital for pilots and air traffic controllers who rely on accurate and timely weather reports to make informed decisions.

The remarks section provides additional information that may not be included in the body but can be important for understanding the current weather conditions, such as maintenance notes about specific observations or historic context that could affect operations.

This structure allows the report to be concise while still providing all necessary details, which is especially important in the coordination of safe flight operations. By having two distinct sections, it ensures clarity and prevents misinterpretation of the data presented.

The other options that suggest a different number of sections do not adequately reflect how a SPECI report is formatted and what constitutes its essential elements.
