← ScienceWhich risk increases when de-icing aircraft wings using hot glycol?
A)Aircraft structural icing reformation rate✓
B)Glycol chemical freezing point depression
C)Aircraft skin-glycol convective heat transfer
D)Reduced water melting point efficiency
💡 Explanation
Ice reformation occurs because hot glycol changes from liquid to vapor phase when cooled by the wing, creating an increased humidity layer ideal for atmospheric icing; therefore, quicker re-icing occurs rather than just delaying the event through initial surface heat transfer.
