Why is it important?

Rapid airport-level noise analysis is simpler with straight-in and -out trajectories, as single event grids can be pre-calculated and stored in advance. If the single event grids for a few common curved trajectories could be identified, they could also be pre-calculated and the benefits of curved paths could also be evaluated rapidly.
