ACS element text (the applicant demonstrates understanding of)

Select and aim for a suitable touchdown point considering the wind conditions, landing surface, and obstructions.

Bottom line

An approach over a large body of water or thick vegetation tends to create a sinking effect that can cause an unwary pilot to land short of the intended landing spot. On final approach, rising air from terrain devoid of vegetation sometimes produces a ballooning effect that can cause a pilot to overshoot the intended landing spot.
