What would the coding be for "7/8ths 2, 1/8th 1"?

The coding for visibility in meteorological reports often uses a specific format to convey information about horizontal visibility. "7/8ths 2, 1/8th 1" indicates that there are obstructions to visibility in terms of fractions of a mile. In this context, "7/8ths" means that visibility is generally clear for 2 statute miles (SM), while "1/8th" indicates an obstruction in the visibility for another 1 statute mile.

The code "2SM; RMK VIS SW 1" accurately captures this essence where "2SM" reflects the general visibility condition, and the remark "RMK VIS SW 1" indicates the visibility condition in the southwest direction, highlighting the additional 1 mile of visibility obstruction. Each component of this message provides crucial information for pilots and air traffic control, ensuring they are aware of the visibility conditions specific to various sectors.

This level of detail is necessary for safe flight operations, as it informs pilots of any potential limitations due to visibility, which is vital for navigation and landing approaches.
