navigate, sail, cruise, fly
航 centers on traveling across a large body of water or through the air: navigating, sailing, cruising, or flying. The common thread is a vessel moving along a planned route.
航 combines 舟 (boat) with 亢, which likely contributes the sound and may relate to a raised or extended shape, together suggesting a boat moving forward. The exact historical role of 亢 is uncertain.
A boat 舟 with a raised sail-like shape 亢 on the right: imagine a ship navigating the seas with its sail catching the wind.
For コウ, picture a boat sailing into a cove: cove -> コウ, and the boat navigates safely into the harbor.
