Abstract. Over the last few years, the reduction of operational costs and control
of pollutant emissions have become central issues for the commercial aviation
industry, and as a result, airlines have been increasingly focusing their attention
on operational fuel saving techniques. However, even though the practical
implementation and economic potential of these techniques have been exem-
plified in a number of papers, little research has been dedicated to a systemic
investigation of the effects of operational fuel saving on the human component of
the system, i.e., the flight crew of an aircraft. This research examines this area,
and investigates the human factors aspects in context with the application of
operational fuel saving on the Airbus A 320 series aircraft. The study presents a
detailed analysis of the flight crew´s performance and motivational factors related
to the topic of interest, which were investigated by means of an online survey and
a controlled simulator experiment. Results of the analysis revealed that the
application of operational fuel saving imposes a number of latent performance
impairments on the flight crew. Motivational factors were shown to be disrupted
by the flight crew´s inability to achieve satisfaction from the application of
operational fuel saving. The implications of these findings are wide-ranging, as
they show, in essence, that the system´s safety and ef ficiency relies solely on the
flight crew´s cognitive flexibility and workload compensation capability, while
structured analyses and conceptual frameworks in regard to the human factors
aspects of operational fuel saving are absent.

1 Introduction
Driven by unprecedented growth rates and constantly evolving markets, commercial
aviation is one of the most competitive business fields worldwide. Characterized by
intense market pressure and heavy overcapacities [1, 2], it is especially prone to macro-
and microeconomic factors such as new business models, predatory competition or
ruinous pricing [1–3]. While these factors are widely cited and broadly acknowledged
in the literature, a more in depth look reveals one variable that seems constantly
