Which aspect is NOT part of SKE rules?

The correct answer indicates that height adjustment is not part of the SKE (Static Line Equipment) rules. This aligns with the fact that SKE rules primarily focus on parameters that ensure a jumper's safety and effective deployment during air operations. The rules typically emphasize the importance of adjusting elements like width, length, and angle to optimize the deployment and trajectory of the descent system.

Width adjustment refers to modifying the equipment settings for better fit and performance. Length adjustment deals with the configuration of the lines or rigging to ensure proper opening sequences and minimize the risk of entanglements. Angle adjustment is crucial for ensuring that the parachute deploys in the correct orientation for a safe landing.

Height adjustment, however, is not typically a factor explicitly addressed within SKE rules, as it doesn't directly affect the equipment's immediate operation or parameters during a jump in the same way the other adjustments do. Instead, height considerations are more relevant to altitude-related training and procedures rather than equipment adjustments under SKE guidelines. This distinction clarifies why height adjustment is excluded from the aspects considered part of SKE rules.
