Low-cost carriers are applying hybrid business strategies in Europe to compete with traditional airlines for more customers. The aim of this study was to investigate the differences between low-cost and non-low-cost carriers on an operational basis in terms of on-time performance, turnaround scheduling, turnaround performance, and block time setting. Data was retrieved from flightradar24.com and analyzed for three major European low-cost carriers and two hub-and-spoke operators for the airport of Valencia. Results indicate that the combination of turning around aircraft quickly and sufficient time on ground to absorb delay is a key factor for success. The findings are relevant for …

This study investigates and compares different methods for improving standard autoclave composite manufacturing in order to find suitable approaches to a more efficient composite production. The goal is not only a reduction in manufacturing times and costs but also quality enhancement. Improved part quality while decreasing costs enables a manufacturer of composite parts to expand its market share, especially in the helicopter market, which has been constantly shrinking over the last two years. Various approaches such as improved tooling technology, the use of automated systems for lamination as well as outsourcing are examined to provide an overview of possible advancements …

Hybrid electric aircraft are expected to enter the small regional aircraft market within the next two decades. The aim of this study was to investigate if a hybrid electric passenger aircraft with 50 seats can be competitive against the established 100 seat aircraft on short range scheduled flights. The Embraer EMB 145 and EMB 190 regional jets were chosen as benchmarks for that market. A hypothetical hybrid version of the EMB 145 with increased fuel efficiency was tested on a cost per available seat mile (CASM) basis. The t tests confirmed significant (p < 0.05) competitiveness of the hybrid version, while in contrast the conventional 50-seater was significantly more expensive compared to the 100seat aircraft. This indicates that hybrid aircraft could enter the short haul market with a competitive advantage, even against the established 100 seat regional jets.
