ABSTRACT 1 This paper presents a method to implement linear holding (LH) for flights subject to ground hold-2 ing in context of the upcoming Trajectory Based Operations in air transportation, aimed at reducing 3 additional delays raised from the lack of coordination between various traffic management initia-4 tives (TMIs) without incurring extra fuel consumption. Firstly, motivated from previous works on 5 the features of LH to absorb delays airborne, a potential applicability of LH to compensate part of 6 the fixed ground holding is proposed. Then, the dynamic adjustment of LH in response to TMIs-7 associated tactical delays is formulated as a multi-stage aircraft trajectory optimization problem, 8 addressing both pre-and post-departure additional delays. Finally, the effects of performing LH 9 are investigated for a particular flight, discussing the changes of vertical trajectory, speed profile, 10 fuel consumption and flight timeline, for each step of optimization. Results suggest that additional 11
