Flaring from half brakes requires a shorter, quicker stroke compared to flaring from a full glide. When a jumper is in half brakes, they have already created some drag, which allows for a more immediate and effective transition to a controlled descent. This means that the flaring action, which aims to reduce speed and increase lift upon landing, can be executed with a rapid motion.
By utilizing a shorter stroke in half brakes, the jumper effectively manages their descent rate and maintains control as they prepare for landing. This technique is advantageous because it allows the parachutist to respond promptly to changing conditions, such as wind or altitude adjustments, thus increasing the precision of the landing.
Other options do not accurately reflect the mechanics of flaring. For instance, stating that it is done more slowly would misrepresent the benefit of flaring from half brakes, which is all about achieving efficient maneuverability and control. A stroke being unnecessary is not accurate either, as some physical input is always required to initiate a flare. Lastly, the idea that flaring is only possible at higher altitudes does not hold, as flaring is an essential aspect of landing regardless of the altitude, as long as the parachute is inflated and flying properly.
