The Impact Of Aircraft Performance Variety In A Departure Sequence Prior to Takeoff Operations Following A Standard Instrument Departure Route

Many earlier efforts addressed the aircraft sequencing issue on the ground prior to departure. Different algorithms and methods were developed to sequence the departure aircraft depending on a variety of variables, including departure time, trajectory after takeoff, and performance. Even when this se-quence is established, we can easily identify a situation with a significant performance mismatch in a departure sequence for a variety of reasons, such as weather, work in progress, or non-routine events. This paper focuses on the performance impact on an aircraft departure sequence that follows the same Standard Instrument Departure SID after takeoff. It also presents various case study situations for the problem and suggests a solution.
