CI-Ops E95
The flight plan is prepared in advance based on variables such as weather, load factors and routing. During the flights these parameters may change, therefore airlines use software to continuously optimise the flight parameters (cruise altitude, airspeed, engine power settings). There is currently no flight planning software installed in the 17 Embraer 195 aircraft. New software is being installed in the Embraer 195 aircraft to improve routing. This measure will lead to a reduction in fuel usage across the fleet.
Flight Profile Optimizer
The flight plan is prepared in advance based on variables such as weather, load factors and routing. During the flights these parameters may change, therefore airlines use permanent software to continuously optimise the flight parameters (cruise altitude, airspeed). In long-haul aircraft this software is already available. Additional software to optimise the flight routing is more precise compared to current systems and can optimise this further. This measure will lead to a reduction in fuel usage across the fleet.
Scavenge Pump
The installation of a fuel scavenge pump in the B777 will lead to a reduction in the amount of unusable fuel. The manufacturer, Boeing, requires as per its design, a minimum amount of fuel in the tank of 320 kg, this amount can be reduced if the fuel can be pumped out totally (e.g. using an additional pump). Such a pump is installed in five Boeing 777 thus reducing the net weight of the aircraft and leading to fuel savings.
E195 Wheel Fairing Modification
With the introduction of wheel fairing modifications on the Embraer 195’s landing gear drag from the air can be reduced. The wheel fairings of the Embraer 195 remain open, as per their design, during flight, causing drag on the aircraft as it flies. 17 Embraer 195 aircraft are expected to be fitted with wheel fairing modifications reducing the aircraft’s drag which will lead to a reduction in fuel usage.
APU & Engines
Simultaneous use of the main engines and the APU (Auxiliary Power Unit) causes an increased demand for fuel. To reduce using them both at the same time, modifications on the aircraft are necessary. Parallel operation of the main engines and the APU is possible even without technical necessity. Following landing and after the prescribed cooling-down time (3 minutes) one of the two engines is shut down when taxiing to the gate in order to save fuel. To do this, the APU must be started in order to maintain full functionality of the fire extinguishing equipment of the engine that is still running. New wiring for the fire extinguishing equipment is therefore necessary. With the new process, an average of four minutes APU time per flight is saved, or annually 504 t across the entire Airbus fleet.
Electric Shuttlebus
For the transport of flight crew around the airport, crew shuttlebuses are used. There are currently 16 Mercedes Sprinter 516 being used, the buses are being modified for use as public transport. The vehicles cover a maximum of 100 km every day and need servicing every 10,000 km (normal maintenance interval 60,000 km), their fuel efficiency is approx. 30–35 litres diesel/100 km. With the introduction of electric shuttle buses, Lufthansa can comfortably reach its aim of CO₂ neutrality by 2030 in ground operations. The energy costs (diesel vs electric) are reduced by around 80% and the operating costs (maintenance of the exhaust gas purifiers) can also be reduced just as significantly. The available models fulfil all requirements as the conventional vehicles. Additional loading possibilities for the vehicles is to be set up on site.
Electric cars
In the „Pool-PKW“ vehicle fleet for the technical base, there are 19 vehicles available. The cars are used predominantly for employees to move around the airport. The mileage of the cars is approximately 3,500 km/year, due to the short distances and low speeds, monthly maintenance is needed on the exhaust particle filters. Additionally, the specific consumption is considered high (e.g. Skoda Octavia 15 litre/100 km). With the introduction of electric cars, Lufthansa can comfortably reach its aim of CO₂ neutrality by 2030 in ground operations. The energy costs (diesel vs electric) are reduced by around 80% and the operating costs (maintenance of the exhaust gas purifiers) can also be reduced just as significantly. The available models fulfil all requirements as the conventional vehicles. Additional loading possibilities for the vehicles is to be set up on site.
In general Austrian Airlines implements energy efficiency measures using its own personnel for Operation Efficiency and Eurowings Europe works with Lufthansa’s department.
Measures in ground-related mobility will in the future require comprehensive monitoring and have the potential to bring big savings by using electric vehicles since maintenance work and energy consumption can be significantly reduced.
Employees will be continuously informed about sustainability activities using screens and broadcasts and are in a good position regarding efficient energy use.
Implementation of the above-mentioned measures is expected in accordance with the following time plan.
