My Two Bob's Worth
downwind:
Ref YABA R14 ILS and AIP ENR 1.5-30 para 5.3.
1. The published DA for the Albany R14 ILS is 480ft (530ft with PEC) which assumes an actual (valid) QNH is available.
2. AIP also indicates that, if an actual QNH is available, published MDAs in the shaded boxes may be reduced by 100ft.
3. Reverse logic would apply (I should think) if an actual QNH was not available ie the DA for R14 S-I ILS would now be 580ft (or 630ft with PEC) if using TAF QNH or 630ft (or 680ft with PEC) if using the Area QNH (para 5.3.3 refers).
This is only my interpretation but, I have to agree, nothing in the book that says my interpretation is correct. Very good question and one that I would like to see an official answer to.
Apart from the Unicom service at Albany, is there an AWIB service at all? What do Skywest (or other operators) do during daylight hours if Unicom is unmanned?
