Is a Cessna 172 permitted to fly into known icing conditions according to the manufacturer?

• A. Prohibited.
• B. Permitted with equipment.
• C. Permitted with permission.
• D. Permitted in lighter icing.

Answer: (A)

Icing limitations and certification determine what airplanes may fly into known icing. For the Cessna 172, the manufacturer does not certify the airplane for flight into known icing conditions. The POH specifically limits this operation, so pilots are instructed not to fly into known icing. This is because the aircraft typically lacks certified anti-icing or de-icing systems, and ice on the wings can rapidly change the airfoil shape, raise stall speed, reduce lift, and make control difficult or unsafe. Without approved ice protection and certification, the risk is not acceptable, so flying into known icing is prohibited. Options that suggest you can fly into icing with equipment, with permission, or in light icing aren’t correct for a standard 172, since the certification and operating limitations do not authorize such operations.
