Which of the following is a correct entry in Column 14 (Remarks)?

In aviation weather reports, Column 14 (Remarks) is used to provide additional information that is not included in the standard format. This column can contain details on significant weather phenomena that may affect flight operations, such as specific types of clouds, visibility conditions, or other pertinent meteorological observations.

The correct entry, which indicates "ACC DSNT NW," refers to "Accumulation (or showers) distant northwest." This remark conveys important information about weather conditions that may not be evident from the standard report alone. By specifying that the significant weather is accumulating from a distance and its general location, pilots and air traffic controllers can better anticipate potential weather impacts during flight planning and operations.

The other options provide information that, while potentially useful, do not appropriately fit the structured format intended for Column 14 remarks. For example, entries like "FG OVC000" or "FU VV005" are more straightforward observations and lack the context of being broader weather phenomena. An entry such as "GS 1/2" could refer to a specific observation of graupel but does not necessarily provide additional contextual information ideal for the remarks section. Thus, "ACC DSNT NW" correctly utilizes Column 14 to enhance understanding of flight conditions.
