Type III fluids are ideal for which aircraft types?

• A. Regional jets
• B. Business aircraft
• C. Regional jets and business aircraft
• D. Large wide-body

Answer: (C)

Type III anti-icing fluids are mid-viscosity formulations designed for lighter, smaller airplanes, providing a practical balance between protection time and ease of handling. They deliver a sufficient holdover time for regional jets and business aircraft, whose wing areas and icing risk are typically less extreme than those of large jets. The bigger wide-body fleet, with larger wing surfaces and greater ice accumulation potential, usually relies on higher-viscosity fluids (Type II or Type IV) to achieve longer protection times. So, regional jets and business aircraft are the best fit for Type III fluids.
