My understanding of this incident is that they arrived over the top with 3500 kgs.Got windshear warning on approach several times.This is a go around requirement at VA.Landed with 1100 kgs,this is below the normal FR (30 mts) of 1200 kgs.
This should be a lesson to all who are encouraging pilots to take less and less fuel down to flight plan fuel.And a message to pilots that you are more than covered by the CAR's to carry whatever fuel you feel you need for the safety of the flight.
Perth is a potentially dangerous place from the point of view of unpredictible weather and poor forecasting.I NEVER go there without Kalgoolie fuel.A lesson proven above.
