Minecraft wiki entry for Elytra, associated text: Sharp turns are a fast way to lose speed. Quicker turns cause greater losses, while gentle movements have small effects. Making a hairpin turn can actually be used for making high-speed landings safe as well as for precise landings on small targets like rooftops. The player aims to glide just above the target, then as they're right over it they immediately reverse directions, then they make readjustments as necessary.
