What considerations arise when operating landing gear in icing conditions?

• A. Ice buildup on tires improves braking.
• B. Anti-ice measures are unnecessary.
• C. Ice can impede movement; ensure anti-ice measures, check seals and hinges for ice buildup.
• D. Only the doors unlocking is affected by icing.

Answer: (C)

In icing conditions, the key issue is that ice can accumulate on landing gear moving parts and sealing surfaces, which can bind or slow operation and interfere with proper extension, retraction, and door/hinge function. The best approach is to use anti-ice measures to minimize ice formation and to inspect seals and hinges for ice buildup, ensuring smooth gear movement and reliable door operation. This addresses the real risk that ice introduces to gear actuation and sealing, which could lead to gear or door binding if not managed.

Ice on tires does not improve braking; it reduces friction and worsens stopping performance. Anti-ice measures aren’t optional in icing conditions because ice buildup on moving parts can jam or hamper gear operation. And icing affects more than just door unlocking; it can impair gear actuation, seals, hinges, and related mechanisms, so relying on that being the sole issue would miss the broader risk.
