Should QANTAS change their fuel policy?

Defeats the purpose, as too many diversions will quickly negate any fuel savings.

Here we go again...
With an Alternate forecast on the TAF a Qantas aircraft would have the alternate fuel or would divert at or before PNR/DPA.

This whole debate hinges on the timing of the alternate declaration and its usually only an issue when an alternate condition arises apparently 'out of thin air'. That the TTF conditions can apparently go from no reasonable chance of alternate conditions (usually fog), to visibility below the alternate minima in a matter of minutes to me indicates a failure of considered weather observation and forecasting, not a failure of the airline's fuel policy.

Sometimes I suspect forecasters rely too heavily on their computer models, rather than taking a walk outside to have a look or listening to the bloke in the tower who's telling him the fog is "just over there" as evidenced in one of the aforementioned ATSB reports.

Sometimes I suspect pilots rely too heavily on forecasters.

Who is ultimately responsible for conducting an emergency auto-land and endangering the lives of hundreds of people?

Interesting concept.

If you rely too much on the forecaster, you will endanger hundreds of lives!

No more forecasts for me then! Just to be safe.

Grrr TAF vs TTF

Isn't the real problem when the TTF does not reflect the "bad news" TAF and is relied on to continue past LPSD?

Which, of course, is to hide the myth that the TTF is "good for 3 hours", when in reality it is only 'good' until the next one is issued - on the METAR cycle or if a SPECI is needed!

Sunny.

We all have access to forecasts. What is your point in posting them here?

There is fog somewhere in the world every hour of the day. Sydney is not unique!

Yes, they should uplift more fuel at Townsville.

Here's the rub... No alternate required at time of takeoff = legal. Airborne, destination Wx declines, originally not forecasted, and no tempo. No brainer. Just select an alternate short of your destination, or use contingency fuel. You do have "Contingency Fuel" uplifted, yes?

The answer to your question is mentioned multiple times within this thread.

Every QF flights departs with multiple arrival airports available to them at a number of places en route. If the weather at that last designated point before their arrival at destination says the weather at destination is suitable then they commit to destination. If the weather deteriorates en route and at that designated point requires an alternate or a fuel requirement that they don't have on board (an INTER or TEMPO for example) then they divert.

And therein lies the "problem" at hand.

That seems a bit extreme. They should at least try for destination

What's with the JQ fuel policy? A BNE-SYD flight diverted to ADL and a AVV-SYD diverted to LST with both overnighting. Cheaper hotel rooms?

I agree scrubba. Hence my candid TAF vs TTF comment back in post #77. I have seen TTFs go from no fog to TTF SPECI fog here NOW - no FM period or BCMG!

Fog is a wily foe and I don't know if we are always capable of knowing what it will do in three hours...

SWA does not fly any international routes, nor does it seem capable of successfully completing ETOPS certification.
You definitely misunderstood the context of what was said. If you want good info, you're not going to get it here. This is a rumour board. Rumour has it, SWA is FAA certified as a Flag airline. ©
