← ScienceWhich risk increases when an aircraft flies through an area of supercooled large water droplets (SLD)?
A)Structural icing on control surfaces✓
B)Engine flameout from fuel contamination
C)Avionics failure due to static discharge
D)Cabin depressurization from fuselage stress
💡 Explanation
When an aircraft encounters SLD conditions, structural icing occurs because the supercooled water droplets freeze rapidly on impact, accreting ice, especially on control surfaces. Therefore structural icing is the primary risk, rather than flameout, avionics failure or depressurization, which are associated with different environmental factors.
