← TechnologyWhich risk increases when an aircraft's flight-spoiler doors activate asymmetrically?
A)Increased parasite drag formation
B)Reduced fuel efficiency ratio
C)An uncontrolled rolling rotation✓
D)Elevated cabin pressure differential
💡 Explanation
Flight-spoiler asymmetry causes differential lift force, triggering **adverse yaw,** because unequal drag induces a rolling moment. Therefore, the risk is uncontrolled roll, rather than solely increased drag or loss of efficiency which could occur symmetrically under controlled deployments.
