- Discretionary Extra Fuel: The flight commander ensures that each flight uplifts enough fuel for safe operations. Depending on the assessment of prevailing operational circumstances, the Captain may choose to uplift extra fuel beyond the minimum stipulated by regulatory standards. This initiative encourages the Captain to uplift extra fuel based on well-founded judgment and legitimate operational needs. The goal is to furnish Captains with pertinent data and analysis, aiding them in making more informed and precise decisions regarding the uplift of extra fuel. With this initiative, the increase in discretionary extra fuel has been reduced significantly.
- Flight speed optimisation: An aircraft’s speed directly impacts fuel consumption and emissions. To accurately calculate the optimised speed for a flight, several considerations are made based on a thorough calculation that seeks to minimise total operating costs while maintaining adherence to departure and arrival schedules. Depending on prevailing operating conditions, pilots may have the opportunity to adjust speed to decrease fuel consumption without compromising the integrity of the flight schedule. This inflight speed management is integral to all Emirates’ pilot SOPs.
- Reduced flap landing: Aircraft have the flexibility to land using a variety of flap configurations. Emirates pilots carefully assess and select the flap setting that minimises aerodynamic drag, reducing fuel consumption. This decision is made without compromising safety and is adapted to different runway conditions.
- Idle reverse thrust: As soon as the aircraft is on the ground, pilots can use different levels of reverse thrust, providing backwards thrust to decelerate the aircraft. Based on prevailing conditions and runway length, Emirates pilots will prioritise using idle reverse thrust to reduce fuel consumption.
- Reduced engine taxi-in (RETI): Aircraft don’t require power from all engines during ground taxiing after landing. Emirates pilots take advantage of every opportunity to engage in reduced engine taxiing by shutting down one or two engines (depending on the aircraft’s engine configuration) upon landing. This practice is implemented without compromising safety or operational efficiency. Since it was introduced, the use of RETI has increased by almost sevenfold.
- Optimised flight routings: A pioneer and early adopter of flight planning efficiencies, Emirates has been using flexible flight routes since 2003. Working directly with air traffic control and other industry bodies across its network, the airline works hard to optimise each route flown between cities. Optimising routings enables Emirates to carry and use less fuel on flights, resulting in lower emissions. It also means time saved for customers.
- Technology and Innovation – Flight Pulse: Emirates introduced FlightPulse (collaboratively developed with GE Digital Aviation Services), an extensive self-service data analytics tool for all its pilots, incorporating crucial elements of operational data and analytics about each flight’s safety and fuel efficiency performance. This tool has significantly transformed the monitoring of flight operations data. The rollout of FlightPulse has fostered improved collaboration between Flight Operations management and the pilot community at Emirates, ultimately enhancing the safety and efficiency of flights. This initiative demonstrates the airline’s commitment to industry innovation through technology adoption to improve fuel efficiency.
- Centre of Gravity Optimisation: The aircraft’s centre of gravity (CG) significantly influences the safety and efficiency of a flight. Loading the aircraft at the optimised Centre of Gravity ensures proper weight and balance, increasing its aerodynamic efficiency and ultimately saving fuel. Emirates has a rigorous policy of loading aircraft to come as close as possible to the ideal trim line to minimise fuel burn.
- APU Usage: Emirates reduces fuel consumption on the ground by minimising the use of the aircraft auxiliary power unit (APU) and instead using the electrical ground power unit (GPU) to reduce emissions. Since introducing this initiative, APU use has been reduced by over 30%.
- Adjusted potable water uplift: Emirates uses an exacting scientific method of calculating potable water required for a flight to reduce weight for more efficient fuel uplift. Each flight uploads the needed amount of potable water without compromising passenger comfort.
