CDM training is about to be conducted with the companies. With respect to GIGO, CDM is reliant on up-to-date information being shared by all parties. Not going to help much if the data is flawed, and I would guess during periods of delays through the network, disruptions, aircraft going unserviceable, then the chances of the data being remotely correct I would guess would be pretty low (inverse relationship).
How often do the companies send a delay? Very low percentage I would have thought.
Wednesday must have been a record number of missed approaches for Sydney, including some aircraft going around twice due weather.
And what's more, the RWY 34R LOC won't be fully replaced until this time next year. New AIP SUP to be issued.
