IF an ALA is not an aerodrome then the way that this new CAAP is written you couldn't use an ALA as an alternate. I wonder if this is a mistake, my misunderstanding or deliberate CASA meddling?
Haven't read it in detail but if your destination requires an alternate, wouldn't you be some sort of IFR operation? Given ALAs are generally just cleared bits of land to plonk on to, how could you use one as an alternate? No Forecast? No Notam Service?
