The area just aft, the shedding zone, is normally kept below freezing, causing the streaming water to freeze and collect as ice. During a de-ice cycle the voltage is increased, raising the temperature of this aft shedding zone, melting the ice bond and shedding the ice via aerodynamic force. Once power is removed from the heater, the shedding ...
Even small amounts of ice will have an effect, and if the ice is rough, it can be a large effect nonetheless. 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 ...
[1]: 36 Combined with the effects of ice on the wing, the high climb rate caused the plane's left wing to stall and the plane to begin rolling over. [ 1 ] : 36 Flight 1713 was Bruecher's first flight after a 24-day absence from flight duties and the NTSB concluded that this prolonged absence had eroded the newly hired first officer's retention ...
The rapid change in shape of the boot is designed to break the adhesive force between the ice and the rubber, and allow the ice to be carried away by the air flowing past the wing. However, the ice must fall away cleanly from the trailing sections of the surface, or it could re-freeze behind the protected area.
A deicing boot is a type of ice protection system installed on aircraft surfaces to permit a mechanical deicing in flight. Such boots are generally installed on the leading edges of wings and control surfaces (e.g. horizontal and vertical stabilizer) as these areas are most likely to accumulate ice which could severely affect the aircraft's ...
Using 1–2 millimetres (0.039–0.079 in) of ice spread over the entire wing, an analysis regarding its effect on the aircraft's lift was carried out. The result indicated that even with such thin ice, the aircraft lost a total of 35% of its maximum obtainable wing lift, and the nose could never exceed 5–6 degrees.

Colder temperatures, lower liquid water content, and small droplets favors the forming of rime icing. Clear ice is glossy, clear, or translucent. Compared to rime ice, clear ice forms relatively slowly and tends to appear with warmer temperatures, higher liquid water contents, and larger droplets. Mixed ice is a mixture of rime and clear ice.
