Can you continue a flight into an area where supercooled large droplet icing conditions exist?

• A. Yes
• B. No
• C. Only with permission from ATC
• D. Not specified in the guidelines

Answer: (B)

Supercooled large-droplet icing conditions are especially dangerous because large droplets can rapidly freeze on contact with surfaces, leading to sudden ice buildup that is hard to shed and can cause loss of lift, degraded aerodynamics, and control issues. Because the risk can escalate quickly and standard ice protection may not prevent dangerous ice growth, pilots are trained to avoid entering areas where SLD icing exists. The safest approach is to divert or deviate to regions free of SLD icing, rather than continue into them. ATC clearance does not make it safe to enter hazardous icing; the decision rests on aircraft performance and safety, not on permission alone.
