Since the groupÃ¢â‚¬™s inception the ASPIRE membership has expanded with the inclusion of Japan Civil Aviation Bureau (JCAB) in October 2009 and the Civil Aviation Authority of Singapore (CAAS) in February 2010.
Ã¢â‚¬Å“When the various aviation service providers came together it was quite clear there are many opportunities to improve air traffic management and with the consequential improvements to operational efficiency which then flow on to environmental benefits,Ã¢â‚¬Â said Civil Aviation Authority of Singapore (CAAS) director, Air Traffic Service, Ng Tee Chiou.
A key initiative of the group to date has been the use of Optimised Profile Descent (OPD), or so-called continuous descent, designed to reduce fuel consumption and noise compared with a conventional approach. The OPD involves maintaining a constant three degree descent angle during landing, until meeting the Instrument Landing System (ILS).
