Hi there.
I have done Practice Tests in Bob Tait Met Book.
From Test1 Qestion No10 from P8.2 please have a loot at attached file 1 ~3

Answer is d but can't quite get that.
5-7 eights is BKN and in ARFOR it says SCT ST 1000/3000
Can anyone please explain to me how come this is d


And also Qestion No 16 from same page please have a loot at attached file 4

Answer is d

TAF of YMIA says visibility 9999 which is 10km or greater
And ARFOR says 4000M SH/DZ/TS
This question is asking visibility for Area 22
And especially according to PCA YMIA is the edge of Area 22&30

Can anyone please also explain to me?

Thank you

Hi Leifie,
The ARFOR for Question 10 says "SCT ST 1000/3000 SW SLOPES, BKN RANGES TILL 08". So, the cloud wil be SCT over the slopes but actually BKN over the ranges. Of the answer options, (d) is the only one that can be correct, even though the bases are BKN only over the ranges.
As for Q16, the ARFOR says the vis is "4000M SH/DZ/TS" which means the visibility is 10km or more unless you are in showers, drizzle or under a thunderstorm.
YMIA may be on the boundary for Area 22 and 30 but to find out which area it belongs to, turn your PCA chart over and find YMIA in the list of aerodromes on the back. That will tell you which area the aerodrome belongs to, which, if I remember correctly is Area 22.
Cheers,
Rich
