Which feature of aircraft carriers allows for safer and more efficient landings and takeoffs?

The feature of aircraft carriers that enhances the safety and efficiency of landings and takeoffs is the angled flight deck. Angled flight decks are designed with a sloped surface that allows aircraft to land while simultaneously providing a separate path for departing aircraft. This design prevents potential collisions and reduces the chance of accidents during operations, as multiple aircraft can be on approach or takeoff at the same time without interfering with one another.

Unlike extended runways, which would not be practical on a moving vessel, angled flight decks maximize space and improve operational flow. Elevated control towers do improve visibility for landing operations, but they do not directly affect the mechanics of landing and takeoff. Deployed parachutes are typically used in certain types of aircraft for recovery during landings but are not a feature of aircraft carriers. Thus, the angled flight deck stands out as a critical component that ensures the smooth and safe functioning of flight operations aboard aircraft carriers.
