Question 10
Domain 2: FAA Part 107 WeatherDecode the following METAR group: "PRESFR".
Correct answer: A
Explanation
PRESFR is a METAR pressure tendency remark meaning pressure is falling rapidly. In METAR coding, "PRES" refers to pressure and "FR" indicates a rapid fall, so the group decodes to "Pressure falling rapidly."
Why each option is right or wrong
A. Pressure falling rapidly
In METAR remarks, the coded pressure tendency group uses the prefix "PRES" for pressure and the suffix "FR" for a rapid fall, so the group decodes to a rapid decrease in barometric pressure. This is the standard METAR remark format used to report pressure tendency, distinct from the 3-hour pressure tendency code in the main report, and it specifically indicates falling pressure rather than steady or rising conditions.
B. Present weather freezing rain
C. Pressure rising
D. Previous report freeze
