Ice accretion on the wing leading edge is a major concern for aircraft not equipped with anti-icing or de-icing. Airflow disruption will reduce the maximum lift coefficient attainable by as much as 30% - 50%, thus raising the stalling speed considerably.
Airframe icing is ice accretions on the airplane, except for the propulsion system.
lowing it to run back and off the protected surface or freeze on non-critical
Where and When Icing Occurs ...
You may expect that ice accretion will not be the same for both wings and that each wing will stall at different speeds and angles. That will introduce a rolling action toward the stalled wing.
De-icing: Removal of ice accretion on an aircraft at an airport - can be done by use of fluids, heating systems and expanding rubber membranes.
The ice type that appears clear near the stagnation line turning to white rime near the edges. It occurs at conditions between those that form pure clear and pure rime ice. Similar to clear ice, mixed ice accretions can significantly disrupt airflow and cause handling and performance problems.
