"Airlines can cut CO2: expert (http://www.smh.com.au/news/breaking-news/airlines-can-cut-carbon-dioxide-expert/2007/02/14/1171405279960.html)"

Getting airlines to follow more efficient flight paths could remove 73 million tonnes of carbon dioxide from the atmosphere each year, a leading aviation expert says.
International Air Transport Association chief executive officer Giovanni Bisignani says airlines need to see the financial benefits in cutting their carbon emissions.



...



Mr Bisignani said the flight path inefficiency translates to financial inefficiency.
"That 12 per cent translates into up to 73 million tonnes of carbon dioxide emissions and nearly $US13.5 billion ($A17.35 billion) in unnecessary fuel costs.



...



Mr Bisignani's comments come at the same time as Australia's airspace controller moves to redraw flight paths and introduce new software which will take weather conditions into account when drawing up daily flight paths.
Airservices Australia is introducing software called Ozops which draws up individual, optimised flight paths for flights in Australian airspace.
A spokesman for Airservices told AAP the traffic controller was also looking at ways of reducing emissions from planes.

...

Planes which arrive early at airports are traditionally asked to circle high in the atmosphere until there is space to land. Planes circling at high altitude burn about 40-50 kilograms of fuel per minute but with ADS-B, the spokesman said, pilots will now be told to slow down while still en route to an airport, thus avoiding the need to circle.

Rather than this nonsense, simply let the computer interweave all incoming tracks to such an extent so that skippers can pull throttles at ToD and not touch them again before touchdown. It's called ACDA/Green Approach and has been going on at ESSA for over a year now.

Screw the 1090ES and go for VDL4 instead, sorted :ok:
