Hi Bob, I am doing my Met exam tomorrow and am pretty well on top of it all having gone through your text and done all tests twice.
I am a bit perlexed (still) with question #5 which states:
VFR will arrive at YCAS at 0040Z - which of the following apply?
(a) No alternate
(b) Fuel for alternate
(c) 30 minutes holding
(d) fuel OR alternate
My answer is (c)
AIP ENR 1.1 57.2.1 says you must provide an alternate OR holding fuel for the various criteria listed as MINIMA.
The TAF for YCAS indicates that Minima are OK on arrival at 0040 however there is a FM indicating rain and BKN cloud at 2000' so that is OK
There is an INTER which takes effect at 1301 so arrival at 0040 must take that into account and the conditions are below both VIZ and Cloud so:
57.2.5 says an alternate is NOT required if you carry fuel to hold for 30 minutes.
Your answer is (d) carry fuel for alternate or hold.
Can you please explain this to me as I cannot see why according to the rules you would not just carry the 30 minues holding. Notwithstanding all that I'd certainly carry fuel for an alternate on a day like this as it is borderline anyway
