What acronym describes aircraft design features that enhance crash survivability?

The acronym that describes aircraft design features which enhance crash survivability is CRASH. This term encompasses various engineering and design principles put in place to protect occupants during an emergency situation. These principles may include features such as energy-absorbing structures, crashworthy seating, and fuel system protections. Each of these features contributes to increasing the likelihood of survival in the event of an accident by minimizing injury and maximizing the structural integrity of the aircraft during impact scenarios.

SAFE, while it may imply safety, does not specifically refer to aircraft design features aimed at enhancing survivability in crashes. CREEP is typically used in a different context, often related to material science and the deformation of materials over time under stress. SURVIVE suggests the outcome of an accident rather than the design or features that ensure such outcomes. Thus, CRASH is the most appropriate acronym associated with the enhancements in aircraft design geared specifically towards survivability in crash scenarios.
