Fuel Flexibility: Fuel-flexible fuel cell systems for super yachts

The reduction of the of harmful emissions that result fromyachting are an increasing concern and priority. It has been widely established that yachts have a significant contribution to the emission of greenhouse gasses and other emissions that are harmful to the environment and the public health. Measures must be taken that drastically reduce...

The feasibility of a fully electric aircraft towing system

Operational towing is a taxiing strategy to reduce the fuel consumption during the taxiing phase of a flight, which decreases the cost and environmental impact of taxiing. Currently, no operational electric towing systems are available that are fully electric, independent from the APU and are capable of towing both narrow- and wide-bodied...

Improved Flexible Runway Use Modeling: A Multi-Objective Optimization Concerning Pairwise RECAT-EU Separation Minima, Reduced Noise Annoyance and Fuel Consumption at London Heathrow

A minimization of disturbance caused by aircraft noise events and a reduction of fuel consumption during the initial and final phase of flight. These are the two objectives that play an important role in the Flexible Runway Allocation Model. By taking into account fuel consumption alongside noise annoyance, this model enables to analyze and...

Tailored SID & Profile Allocation for Amsterdam Airport Schiphol

Currently, only one Standard Instrument Departure (SID) track and one flight procedure is used per runway departure fix combination. In contrast to tailored arrivals, the potential benefit of tailored departures has been left relatively undiscovered. The research objective is to quantify the potential benefit of tailored SID-s and profile...

Flexible Arrival & Departure Runway Allocation Using Mixed-Integer Linear Programming: A Schiphol Airport Case Study

Runway capacity of a complex runways system can be limited by several factors. Currently, the runway usage at Amsterdam Airport Schiphol (AAS) is described by a preference list established by multiple stakeholders. It makes an important trade-off between minimizing noise exposure to the environment and maximizing capacity. The existing model...

Improving fuel decisions by airline pilots in flight preparation and execution

High fuel prices and strong competition have put pressure on airlines to reduce costs and become more efficient. For KLM fuel costs were $3.9bn in 2013: 31% of the total expenses. Therefore, focus has been put on fuel efficiency programmes. The pilot in command, the captain, has the final decision about the fuel quantity taken on board of an...
