09 - Air Transport System EfficiencyAIRCRAFT BOARDING AS PART OF AN EFFICIENT 4D TRAJECTORYM. Schultz, DLR, Germany A reliable 4D aircraft trajectory demands for efficient ground handling procedures at the airport to ensure punctual aircraft operations. The aircraft turnaround holds the potential for compensating delays and for providing a more stable handling process. Aircraft boarding is driven by individual passenger behavior and has to be efficiently considered in airline/airport operations. |
