Dubai Air Navigation Services (DANS) has successfully implemented the innovative Approach Peak Offload (APO) procedure that has led to an increase from 33.2 to 34.8 in average air traffic movements for arrivals during peak hours, as well as reduction of peak arrival delay by 40 per cent at Dubai International Airport (DXB).
HE Mohammed Ahli, director general of Dubai Civil Aviation Authority (DCAA) and CEO of DANS stated that under the guidance, sponsorship and leadership of DANS chairman HH Sheikh Ahmed Bin Saeed Al Maktoum, the ANSP was committed to and continuously striving to “Transform the Sky” through developing and launching several key air traffic movements capacity enhancement projects in the Emirate of Dubai.
He added: “Developing and implementing innovative procedures such as Approach Peak Offload (APO) have enabled us to deliver enhanced air traffic management services and accommodate the rising demand of our prestigious clientele with up to 86 per cent during peak hours. We have significantly invested our resources in thoroughly assessing the procedure from 1 March and until its implementation in live operations through fast time and real time simulation exercises, this in turn has reinforced our efforts in building the safety case of the procedure which has been approved for implementation by the General Civil Aviation Authority (GCAA).”
Exclusively designed and developed by the experienced operations team in DANS, the APO procedure was created for the Dubai operational environment reflecting the most advanced solutions in the aviation community. The procedure is one of several solutions implemented by DANS to drive further efficiency in the aviation sector, as it increases the volume of air traffic movements, while reducing possible delay timings for airlines.
Since its recent implementation, the APO procedure has reduced peak arrival delay for Dubai arrivals which delivers effective reduction of fuel consumption and cost savings for the airlines. This has also enabled DANS to play a key role in enhancing the overall traffic flow efficiency while concurrently playing an active role in conserving the environment, as the implementation of this procedure enabled reduction of CO2 emissions by up to 447 tons on monthly basis.
The APO procedure is a concept that is based on the re-allocation of lighter wake producing category aircraft to Runway 30R during arrivals peak periods, thus accommodating the arrival flow more efficiently with the concurrent use of both runways at Dubai International Airport. One of the key components of this unique procedure permits lighter category aircraft to maintain a horizontal separation of 4.5nm behind the A380 ‘Super’ aircraft while landing. Experts at DANS reached the new wake separation minima levels between aircraft based on the results of the safety case which included an in depth quantitative and qualitative wake data analysis.
DANS is the ANSP that manages the Dubai and Northern Emirates airspace. It also provides air navigation services for airport authorities and numerous prestigious airlines, including the world’s busiest airport in terms of international passenger numbers-Dubai International Airport (DXB).
