How is a wind report of 6900948 read in a Flight Broadcast?

The wind report 6900948 can be broken down into its components to be understood correctly. The first two digits, 69, indicate the wind direction in tens of degrees, representing 190 degrees. The next two digits, 00, designate the wind speed in knots, which here are not indicated (when the wind speed is less than 1 knot, it may be reported as zero). The final two digits, 48, typically represent a period of observation or may refer to other context-specific conditions.

Therefore, when decoding this wind report, you read it as "Wind one niner zero," which corresponds to the 190 degrees, followed by "at" and then the wind speed, which may be a non-standard zero to indicate calm conditions or light winds. This aligns with the information provided in the correct choice.

The other choices present different readings of wind directions or speeds which do not correlate with the interpretation of this particular format of the wind report. Each of them interprets the leading digits incorrectly or assigns erroneous directions and speeds not supported by the format of the report itself.
