What does CIG 017 RWY 11 indicate about the weather conditions?

The notation "CIG 017 RWY 11" refers specifically to the ceiling of clouds over a specified area, in this case, Runway 11. The abbreviation "CIG" stands for cloud ceiling, and the number following it, "017," indicates 1700 feet. Therefore, this means that the ceiling is at a height of 1700 feet above the runway.

This information is crucial for pilots and air traffic control, as it helps determine visibility and safety for takeoffs and landings. Knowing the ceiling height allows pilots to assess whether they will have sufficient clearance for their flight operations in and around the airport.

The other options imply nuances that aren't indicated by the METAR report. For instance, the mention of clouds being over the runway (as in option B) misinterprets the specific language used; the ceiling is a direct measure rather than a description of cloud presence. Similarly, while option C suggests specific proximity to the runway threshold, it does not accurately reflect the general meaning of "CIG" as interpreted in aviation weather reporting. Option D includes an ambiguous reference to "above 1700 feet," which does not align with the precise measurement given in the METAR. Thus, the reference point of
