Martin Lindner is a research associate at the Chair of Air Transport Technology and Logistics at Technische Universität Dresden since 2014. He achieved his diploma degree in Transport Engineering at the same academic institution and aspires a Ph.D. thesis dealing with optimum aircraft assignment and scheduling based on individual aircraft performance. In his internships at major German airlines and air traffic control as well as the MEFUL project, he specialized in flight and fuel efficiency, ecological sustainability in aviation, and optimized fleet planning. He currently works in the ProfiFuel project bringing together optimized trajectories and live aircraft performance data into the cockpit.

PhD

TAILSIGN-OPTIMZED FLIGHT SCHEDULING AND ROTATION PLANNING

Fleet planning is one of the most important planning steps for an airline and implies high costs for purchase and maintenance of the aircrafts. Aircrafts are subject to steady deterioration effects in flight operations. This concerns notably engines and airframes efficiency, but also aircrafts operating empty mass increases over time. Consequently, the average fuel consumption is higher for the same performed flight with a deteriorated aircraft.

Flight scheduling and aircraft rotation planning example.

These effects are already taken into account in operational flight planning (e.g. fuel calculations for each individual flight) but long-term efficiency loss is only rarely respected in aircraft rotation planning. In most cases, aircrafts of one fleet series are only treated as identical and are scheduled based on maintenance events and other restrictions. Considering performance degradation and the resulting fuel and operating cost deviations in the tail assignment process, each aircraft will be allocated to flights such that a cost minimum solution is found. The thesis investigates the upcoming fuel and cost saving potential by considering different aircraft performance characteristics and efficiencies in flight planning. For this purpose, additional fuel consumption caused by several deterioration effects is calculated. Consequently, using an integrated long and short term flight scheduling and aircraft assignment model, cost and fuel minimum rotation solutions can be found.
