Which factor limits Helicopters directed to "snuggle up" during landings?

The factor that limits helicopters directed to "snuggle up" during landings is primarily related to the distance from the ship. When helicopters approach landing, they need to maintain a safe distance to avoid potential hazards such as the ship's movement, other aircraft or personnel on the deck, and to ensure proper alignment with the landing area. Keeping a controlled distance also allows for adequate space to perform necessary maneuvers and adjustments during the final approach, contributing to the overall safety and stability of the landing process.

While altitude is important during landings, especially for maintaining a safe approach, it does not directly dictate how closely helicopters can approach the ship. Weather conditions play a significant role in flying but may not specifically limit the ability to snuggle tight during a landing scenario, as the focus is more on visual cues and spacing in relation to surrounding objects. Wake turbulence, though a concern, is more applicable to fixed-wing aircraft and is less of a limiting factor in the unique dynamics of helicopter landings. Therefore, the distance from the ship stands out as the main limiting factor in this context.
