What should a jumper do before attempting a stand-up landing?

Executing a good flare at the appropriate altitude is crucial before attempting a stand-up landing because it significantly impacts the landing's effectiveness and safety. A flare involves pulling down on the parachute's toggles to create lift just before touchdown, which slows the descent rate and reduces horizontal speed. This action helps in managing the landing, allowing the jumper to transition smoothly onto their feet. Performing the flare at the correct altitude ensures that the parachute has time to respond properly, allowing the jumper to land gently and reduce the risk of injury.

While confirming the landing area is free of obstacles, maintaining a speed of at least 10 mph, and ensuring all equipment is functioning properly are important considerations in the overall landing process, the flare is the immediate action that directly affects the landing execution itself. Thus, focusing on the flare competency is essential for a safe and successful stand-up landing.
