Question 29
Domain 2: FAA Part 107 WeatherGiven METAR: "KABC 121755Z 09014KT 2SM BR OVC005 08/07 A3000", what is the ceiling?
Correct answer: A
Explanation
In a METAR, ceiling is the height of the lowest layer reported as broken, overcast, or obscuration. The report says "OVC005," which means an overcast layer at 500 feet AGL, so the ceiling is 500 feet AGL.
Why each option is right or wrong
A. 500 feet AGL
Under FAA/AIM METAR conventions, the ceiling is the lowest cloud layer reported as broken (BKN), overcast (OVC), or vertical visibility/obscuration. In this report, "OVC005" decodes to an overcast layer at 500 feet above ground level, so the ceiling is 500 feet AGL; the other elements (2SM visibility, BR, 08/07, A3000) do not change that value.
B. 5000 feet AGL
C. 800 feet AGL
D. 300 feet AGL
