Effect of Icing
The wing will ordinarily stall at a lower angle of attack, and thus a higher airspeed, when contaminated with ice. Even small amounts of ice will have an effect, and if the ice is rough, it can be a large effect. Thus an increase in approach speed is advisable if ice remains on the wings. How much of an increase depends on both the aircraft type and amount of ice. Stall characteristics of an aircraft with ice contaminated wings will be degraded, and serious roll control problems are not unusual. The ice accretion may be asymmetric between the two wings. Also, the outer part of a wing, which is ordinarily thinner and thus a better collector of ice, may stall first rather than last.

“I guess what I’ve really discovered is the humanizing effect of children in my life—stretching me, humbling me. Maybe my thighs aren’t as thin as they used to be. Maybe my getaways aren’t as glamorous. Still I like the woman that motherhood has helped me to become.”
—Susan Lapinski (20th century)
“Mix salt and sand, and it shall puzzle the wisest of men, with his mere natural appliances, to separate all the grains of sand from all the grains of salt; but a shower of rain will effect the same object in ten minutes.”
—Thomas Henry Huxley (1825–95)
