Final answer:
A survival suit is required for each person on flights beyond 50 nm from shore; selection should prioritize safety and suitability.
Step-by-step explanation:
For flights beyond 50 nautical miles (nm) from shore, a survival suit is carried for each person on board. While some people might choose a raft based on its color, or simply prefer the largest one available, the priority for safety equipment should not be personal preference but rather the effectiveness and suitability for the task at hand. A sensible person would select the best possible raft or survival equipment that will ensure the safety and survival of its occupants in case of an emergency at sea.
