Once ice accumulates on an airframe it can turn you into an accidental test pilot, flying an aircraft with unknown handling characteristics. Ice can affect the stall speed, which is particularly important during landing and takeoff. Even an aircraft certified for "known ice" can suffer degraded performance when operated in severe icing conditions.
Since 1990, there have been more than 100 fatal accidents attributable to ice. With winter coming, the AOPA Air Safety Foundation is offering two safety advisors for free download, " Aircraft Icing" and " Aircraft Deicing and Anti-icing Equipment."
