This chapter first introduces the context of the ground holding policies. The purpose of this ground holding scheme is to respect the en route capacity constraints provided by each air traffic control center (ATCC) as a number of aircraft per hour, according to their daily schedule. The ground holding model uses as input a set of temporal conflict constraints computed for each pair of flights that intersect in the three spatial dimensions. The chapter then describes Allignol's model of a conflict‐free slot allocation, starting by the conflict detection and details on the data structures, operators and parameters used in the evolutionary algorithm. The flight level (FL) of the detected conflicts can be filtered, for example to only consider conflicts occurring within the upper airspace. The results presented in the chapter were obtained with the assumption that aircraft were able to follow their 4D‐trajectory precisely.
