The debate about fuel & mayday calls are secondary. Why can we not provide better quality alternate airports?
Or better quality primary airports. Some CAT II/III facilities would have prevented/helped 7 fog related incidents that have occurred in the last 2 months!!
Far too many aircraft are today being flown with far too insufficient fuel, and this is not company specific. Companies are making roadshows out of pilots' fuel carrying, but the CARs clearly say that the PIC is responsible for carrying sufficient.
That is a circular argument as shown on the QF autoland thread. How much is enough? Both these aircraft had enough fuel to fly to ADL then an alternate, what then?
