Answer 1

The forecast for KFAF indicates that there will be rain-showers after 1200 Zulu and at 1800 Zulu, the ceiling will be 12,000 ft.

Step-by-step explanation:

The given forecast for KFAF consists of several sections, each representing a different time period. We need to analyze each section separately to determine which statements are true. Section 'BECMG 2223' indicates that from 2200 to 2300 Zulu, the wind will change to 130 degrees at 10 knots and there will be scattered clouds at 3,000 feet, broken clouds at 8,000 feet, and overcast clouds at 15,000 feet. This implies that statement c is true because the ceiling will be 12,000 feet at 1800 Zulu. Section 'BECMG 0506' shows that from 0500 to 0600 Zulu, the wind will be 160 degrees at 8 knots, the visibility will be 8,000 feet, and there will be light rain and mist with scattered clouds at 2,000 feet, broken clouds at 3,000 feet, and overcast clouds at 8,000 feet. This means that statement b is false because the visibility is 8,000 feet from 0500 to 0600 Zulu. Based on this analysis, the correct answer is option c, which states that there will be rain-showers after 1200 Zulu and at 1800 Zulu, the ceiling will be 12,000 ft.
