“…The electric taxiing system weight varies from 136 kg (WheelTug) to 300 kg (EGTS), and this additional weight may be for compensated by less fuel carried for the taxiing phase ( 4 , 5 ) . However, strict limitations for carrying taxiing fuel on e-taxiing aircraft may still be imposed by aviation authorities considering the reasons of safety ( 6 ) . According to the analysis of A320 fuel performance, the additional fuel burn for carrying every 100 kg of weight varies between 3 kg and 9 kg with related sector length from 1.5 h to 3 h ( 7 ) .…”

This paper presents the work carried out to evaluate the benefits and performance impacts of introducing a hydrogen fuel cell powered electric taxiing system to a conventional short-haul aircraft. Tasks carried out in this research and reported in this paper include the initial system design, hydrogen tank initial sizing, calculation of the impact on fuel burn & emissions and the evaluation of the effects on Direct Operating Cost (DOC). The Airbus A320 has been selected as the datum aircraft for sizing the system and the benefits analysis is particularly focused on the fleet composition and financial data of a Europe based, low-cost, large-scale A320 family operator in 2016. The maximum power capacity of 400 kW has been sized based on the rolling friction coefficient of 0.02. Based on the operator's 2016 financial, up to 1% fuel reduction can be achieved using the proposed system and the reduction in total maintenance cost is expected to be up to 7.3%. Additionally, up to 5.97% net profit improvement is estimated in comparison with the annual after-tax profit of the datum operator in 2016.

“…The value of acceleration is determined only on the basis of the crews' subjective feelings, so as to prevent any reducing of comfort of the passengers. This information is then, based on the pilot's training and experience, transferred to deflections of tiller (nose gear steering wheel), throttle lever and brake pedals [9,10].…”

The article focuses on the possibility of automation of taxiing, which is the part of a flight, which, under adverse weather conditions, greatly reduces the operational usability of an airport, and is the only part of a flight that has not been affected by automation, yet. Taxiing is currently handled manually by the pilot, who controls the airplane based on information from visual perception. The article primarily deals with possible ways of obtaining navigational information, and its automatic transfer to the controls. Analyzed wand assessed were currently available technologies such as computer vision, Light Detection and Ranging and Global Navigation Satellite System, which are useful for navigation and their general implementation into an airplane was designed. Obstacles to the implementation were identified, too. The result is a proposed combination of systems along with their installation into airplane's systems so that it is possible to use the automated taxiing.

Abstract-This article focuses on the use of thermal imaging in aviation. In the never ending pursuit of lower costs, the Thermal Imaging offers shorter inspection times thanks to its application in aircraft inspections and can reduce the number of costly goarounds using the Enhanced Vision System, which also increases safety in one of the most dangerous parts of flight. Thermal Imaging also offers solutions for Airport Perimeter Security and it can be used for construction of ground surveillance system.
