Encoded and/or plain language information that elaborates on data in the body of the report may be appended to which report?

• A. PIREP
• B. METAR
• C. TAF
• D. SIGMET

Answer: (B)

The METAR has a remarks section where encoded or plain-language information can be added to elaborate on the data in the main body. This RMK part lets weather observers provide extra details that don’t fit neatly into the standard fields—things like recent weather trends, additional clarifications about observed phenomena, sensor or data quality notes, or other context that helps interpret the reported conditions. The other report types—pilot weather reports, forecast advisories, or forecasted weather—do not use this same remarks mechanism to expand the body data, so the ability to append such elaboration is specific to METARs.
