Aircraft to fly closer in trial
With massive up gradation in air traffic control (ATC) equipment, the horizontal distance between two aircraft in the airspace will be reduced from 80 nautical miles to 50 nautical miles “on a trial basis” from November this year on two international flight path routes that pass through the Delhi Flight Information Region. The advanced
equipment and position determination will apparently ensure that there will be no compromise with air safety standards. This will also ensure that more aircraft are able to use a designated airspace.
“Reduction of horizontal separation to 50 nautical miles (NM) from 80 NM has been planned on trial basis on N571 and P628 under guidance of then ICAO regional office with effect from November, 2010. Reduction in separation to 50 NM will permit more flights at the economic flight levels and increases the enroute and terminal area control capacity,” the civil aviation ministry stated on Saturday.
The government also stated that the Air Traffic System (ATS) automation system in Delhi is being upgraded to the Autotrack-III and that the Ground-based Augmentation System (GBAS) is being planned for introduction at Delhi airport by the end of the year. The GBAS will support aircraft movement at multiple runway ends.
