Which of the following factors are part of the aircraft occupant survivability criteria?

The correct response identifies several critical factors that contribute to aircraft occupant survivability during an accident or crash scenario. Crash forces transmitted are pivotal because they directly relate to the impact an aircraft and its occupants experience during an accident. High crash forces can lead to severe injuries or fatalities, making it essential to consider how these forces are mitigated by design and structure.

Occupiable living space is significant as it refers to the physical space available for passengers and crew. More space can enhance survivability by ensuring that there is room for occupants to brace for impact and move to safety post-crash. Aircraft design features encompass various elements such as material strength, cockpit and cabin layout, and safety features that influence passenger safety.

In contrast, the other options do not encapsulate the essential criteria as effectively. For instance, the size of the aircraft and passenger weight distribution is important for overall performance but are not as directly related to survivability in crash scenarios. Weather conditions and altitude can contribute to accident circumstances but do not inherently improve or degrade the survivability of occupants in a crash scenario.

By identifying these specific elements, the correct answer holistically addresses the framework of survivability in aviation safety.
