An Etihad Airways Airbus A330-200 has become the first aircraft in the region to perform the environmently friendly approach method RNP-AR (Required Navigation Performance - Authorisation Required).

The successful demonstration flight today (24 May) marks the beginning of full RNP-AR implementation within Abu Dhabi's airspace, the airline says.

Airbus subsidiary Quovadis has designed the navigation technology, which uses continuous descent operations and shorter trajectories to shorten approach paths to the runway.

Etihad estimates that RNP-AR reduces fuel consumption by between 100-200 kg per approach, cutting the carrier's CO2 emissions by an estimated 20,000 tonnes per year.

Quovadis was contracted by Etihad and the Abu Dhabi Airport Company (ADAC) in 2011 to develop RNP-AR procedures for both Abu Dhabi International and Al Bateen Executive airports.

Abu Dhabi International has gained approval for the system as of today, while Al Bateen will submit RNP-AR procedures to the authorities by the end of the year.
