Hi again,
In Bob Tait's book, some forecast questions have me a little confused.
The alternate requirements as per AIP state that an alternate is required with 8km visibility, and a close base of 1500 ft more than SCT.
So does this mean you require an alternate at [u][i]8km?[/i][/u] A question in Bob Tait's textbook refutes this, but the wording in AIP confirms this.
Also, when it says more than SCT with a ceiling of 1500ft, does that mean you require an alternate at when 5/7ths+ are at 1500ft or when it's 5/7ths+ at 1499 ft and below.
Thanks for continued help.
Hi. AIP ENR 1.1 para 11.7.2.13 (p ENR1.1-93) states that the VFR "alternate minima are a ceiling of 1500ft and visibility of 8km". I understand this means that if the visibility is less than 8km and the cloud is more than SCT with a base lower than 1500ft an alternate is required. They are the minima allowed without requiring an alternate. So with 8km visibility and more than SCT cloud with a base of 1500 you don't need an alternate.
