← TechnologyWhich risk escalates sharply during icing conditions aloft if a pressurized aircraft experiences sudden, rapid decompression?
A)Explosive ice crystal propagation
B)Accelerated structural fatigue cracking
C)Pressurized water vapor condensation✓
D)Sublimation-induced aerodynamic stall
💡 Explanation
Condensation occurs aloft because air suddenly cools due to adiabatic expansion in rapid decompression, triggering rapid cloud formation within the aircraft. This phase change inside the aircraft inhibits visibility and compromises electrical systems, therefore the danger from condensation escalates, rather than the more gradual effect of structural fatigue.
