Flextracks
High altitude jet-stream winds can dramatically affect an aircraft’s speed and fuel consumption on long distance flights.
Flextracks, which diverge from fixed or direct routes, are designed to use these winds to an aircraft’s advantage and avoid strong headwinds.
Airservices National Operations Centre calculates and publishes Flextrack information for airlines flying into and out of Australian airspace to enable them to make the most of prevailing weather patterns and winds.
Flextracks allow aircraft to improve flight time and reduce fuel usage, delivering considerable environment benefits (through a reduction in emissions) and reducing operating costs for airlines.
Flextracks are now being used widely between Australia and airports in Asia and the Middle East.
