“…In terms of energy source, the WheelTug on-board ETS is powered by the APU S/G, whereas its mechanical drivetrain is characterized by a planetary gearbox [30]. The overall ETS weights 130 kg [57] featuring a maximum taxiing speed of approximately 9 knots (16.7 km/h) against the 30 knots (55.6 km/h) normally reached in conventional taxiing [58].…”

The ever-increasing demand for passenger air traffic results in larger airline fleets every year. The aircraft market forecast reveals an unprecedented growth for the coming decades, leading to serious environmental and economic concerns among airlines and regulatory bodies. Different approaches, for both airborne and ground operations, have been proposed to reduce and control emissions without compromising profit margin. For on-ground activities, the electric taxiing (ET) methodology is one of the suggested solutions for reducing the emissions and the acoustic noise in the airport, and for lowering the fuel consumption and operating costs. This paper thus aims to review and collate the more important literature related to electric taxiing systems (ETSs), in order to draw an inclusive picture regarding the current state of the art of a moving and growing sector that just started its first steps towards an ambitious target. After introducing the general concept of ET, elaborations on the benefits and challenges of available technologies are done with a detailed comparison of the different systems. Finally, recommendations for future research and outlook on ET are presented.

“…This option would, in turn, allow the use of two airport bridges for passengers boarding procedure, which would shorten the aircraft turnaround time. If this concept is to be applied on a bigger scale it will create new slots, resulting in reduced airport congestion [84].…”

“…As such, an ETS reduces fuel consumption, since the need for a tow truck is eliminated, as well as the need for running the aircraft's engines on the ground. Next to reducing fuel burn and emissions, an ETS may increase the efficiency of the pushback procedure, as aircraft can push back autonomously with an ETS [1].…”

“…In [1] it is argued that, especially at congested airport like AMS where gate pit-stops are not yet commonly used, the use of ETS can be of essential importance to increase the number of gate pit stops. This is mainly because ETSs eliminate the need for tow trucks and therefore no extra demands are placed on tow truck resources when introducing gate pit-stops with ETS equipped aircraft.…”

One of the infrastructural components that limits airport capacity is the available gate capacity. In order to use existing airport infrastructure, especially gates, more efficiently, one can look at new techniques to relieve congestion. One such technique is introducing socalled gate pit-stops. By introducing gate pit-stops, aircraft will be towed to a remote parking position between arrival and departure from the gate, in order to make space for other flights in the meantime [1]. The main risk of introducing gate pit-stops in airport operations is that the additional towing movements will inevitably increase the number of apron movements, potentially interfering with other traffic on or near the apron. As such, the main challenge in introducing gate pit-stops is modelling and integrating gate and apron movements, where a tradeoff can be made between gate utilization, towing movements, turnaround times and gate flexibility. Additionally, technological innovations such as an Electric Taxi System (ETS) need to be assessed as they can have a big impact on apron operations. Therefore, the effectiveness of gate pit-stops needs to be assessed, as well as the impact of factors such as gate utilization, towing movements and turnaround times on the effectiveness of such gate pit-stops.
