Hi guys!
Here is something I am confused about
:
According to EU-OPS (or PART-OPS; not sure about the name) it states at
CAT.OP.MPA.180 Selection of aerodromes — aeroplanes that
(c) The operator shall select two destination alternate aerodromes when:
(1) the appropriate weather reports and/or forecasts for the destination aerodrome indicate that during a period commencing one hour before and ending one hour after the estimated time of arrival, the weather conditions will be below the applicable planning minima; or
(2) no meteorological information is available.
AND a after a few pages at
CAT.OP.MPA.245 Meteorological conditions — all aircraft says that:
(a) On IFR flights the commander shall only:
(1) commence take-off; or
(2) continue beyond the point from which a revised ATS flight plan applies in the event of in-flight replanning,
when information is available indicating that the expected weather conditions, at the time of arrival, at the destination and/or required alternate aerodrome(s) are at or above the planning minima.
So, if you cannot take off when the weather at destination is below the planning minima, what it's the point of choosing 2 alternate aerodromes?
Because when the weather at destination is above planning minima at +/-1hr ETA, you only need 1 alternate.
