← TechnologyWhich risk predominates when a long-range aircraft encounters clear-air turbulence during cruise?
A)Compressor stall occurs violently.
B)Skin friction drag drastically increases.
C)Adverse yaw initiates uncontrollably.
D)Flameout of engines can occur.✓
💡 Explanation
Flameout risk increases due to momentary fuel starvation; the fuel pump inlet uncovers because of the aircraft encountering rapid changes in attitude during clear-air turbulence. This induces short-term negative g-forces, therefore causing the engine to flameout rather than maintain consistent thrust under constantly positive loads.
