The improved network structure of Azerbaijan Airspace and direct route assignment (DCT) procedures implemented by AZANS are contributing factors in reducing aircraft fuel consumption and mainly for CO2 emission. AZANS ATCOs based on close and instant cooperation with military aviation are able to direct flights by assigning shorter routes via Azerbaijan Airspace and thus effective and efficient airspace utilization.
Continuous Climb Operations and Continuous Descent Operations (CCOs and CDOs)
Continuous Descent (CDO) / Continuous Climb Operations (CCO) implemented in Azerbaijan Airspace is one of the beneficial environmental solutions in high-density operations. CDO/CCO permits maintaining optimal vertical profile, avoiding horizontal phase in climb/descent operation. This allows for the reduction of excessive CO2 emissions by a significant reduction of fuel consumption and takes into account the preference of the Airspace User for the most efficient climb/ descent profile for the flight.
Noise Abatement Procedures
Noise is a principal environmental issue for aviation, in order to overcome challenges expressed by noise AZANS develops and implements noise-reduction measures at and around Heydar Aliyev International Airport. Effectively designed SID/STAR routes and implemented prohibited area UB3 over the city center help to mitigate problems carried by noise.
Reduced Vertical Separation Minima ( RVSM)
AZANS introduced RVSM in Azerbaijan Airspace in 2011 reducing air quality impact in the upper atmosphere. By implementing RVSM Azerbaijan Airspace capacity greatly increased allowing aircraft to fly at more optimal altitudes. Operations in the RVSM environment benefited from less fuel burn and Carbon Dioxide, Sulphur Oxide, and Water emissions.
CO2 emission control
Aviation’s impact on climate change is measured by an analysis of fuel use and CO2 reduction. AZANS does its part to reduce aviation’s impact on the environment by closely monitoring the amounts of pollutants released into the environment. Since 2018 AZANS calculates CO2 emission KPI in Azerbaijan Airspace for FIR, En-route (ENR, and Landing-take-off Operations (LTO) by which the effectiveness of implemented measures can be tracked.
Performance-based navigation. RNAV/RNP
AZANS implemented PBN solutions for advanced air traffic management as a key enabler for direct environmental benefits. PBN enables more efficient aircraft operations resulting in opportunities to both reduce Greenhouse Gas (GHG) emissions and options for reducing the aggregate production of aircraft noise.
- RNAV/En-route environmental solutions
AZANS use RNAV 5 specification on en-route operations to enable aircraft to fly on any desired flight path routes providing Optimum profile descent (OPD) capability, and thus leading to significant reductions of CO2 emissions and fuel consumption.
The RNP approach is one of the most precise approaches to equipment that can reduce noise, emissions, and fuel consumption providing continuous climb operations (CCO) and continuous descent operations (CDO) for arriving aircraft. AZANS implement RNP 1 navigation specifications in order to take advantage of the effective SID/STAR schemes that better avoid noise-sensitive areas and appropriately address the issue.
Efficient TMA design and utilization
Yearly AZANS provides services to over 40 000 aircraft at national airports forcing TMA and structures to be more efficient and environmentally friendly. Putting forward the TMA operational design improvements AZANS thrives to ensure enhanced flight efficiency in TMAs which includes RNAV approaches, airspace design, and continuous descent approach (CDA). Solutions directed to the optimization of SID/STAR and aerodrome structure reduce the environmental impact caused by fuel consumption as well as CO2 emissions in the atmosphere.
