Satellite steering
Aircraft flying over Calcutta lose precibus time awaiting instructions from overburdened ground con- trollers. The Calcutta air corridor is a notorious bottleneck in international air traffic, and airline carriers, Iiike Qantas, lose millions of dollars due to delay there, each year.
But this may soon change with a new satellite-based traffic management system, called the Future Air Navigation System (FANS), that is being sponsored by Air India.
FANS makes use of satellites to track a plane and then position it on maps on an onboard computer. This will reduce an aircraft's dependance on ground control.
