No, not the landing at the top of the staircase... I'm talking about the landing of a plane at an airport... or, for that matter, the landing of a bird on the roof.
The Hebrew word is נְחִיתָה (ne-khee-TAH). It comes from the root נ.ח.ת (n.kh.t). The verb to land is לִנְחוֹת (leen-KHOHT), as in הוּא צָרִיךְ לִנְחוֹת כָּל רֶגַע (hoo tsah-REEKH leen-KHOHT kohl REH-gah) - He is supposed to land any minute.
