Ice buildup can change the shape of airfoils and flight control surfaces, degrading control and handling characteristics as well as performance. An anti-icing, de-icing, or ice protection system either prevents formation of ice, or enables the aircraft to shed the ice before it becomes dangerous.
This can be done visually or by means of specially designed Ground Ice Detection Systems. [2] If frost, ice, or snow contamination is observed or suspected, the aircraft must undergo a deicing procedure before takeoff, using one or more of the methods listed below.
An ice detector is an instrument that detects the presence of ice on a surface. Ice detectors are used to identify the presence of icing conditions and are commonly used in aviation, [1] unmanned aircraft, [2] marine vessels, [3] wind energy, [4] and power lines. [5] Ice detection can be done with direct and indirect methods.
On aircraft powered by jet engines, a similar system is used for wing anti-icing by the 'hot-wing' method. In icing conditions, water droplets condensing on a wing's leading edge can freeze. If that happens, the ice build-up adds weight and changes the shape of the wing, causing a degradation in performance and possibly a critical loss of ...
Aircraft that regularly operate in icing conditions have systems to detect and prevent ice forming (anti-icing) and/or remove the ice accumulation after it has formed (de-icing). This can be achieved by heating the spaces in internal structure with engine bleed air, chemical treatment, electrical heating and expansion/contraction of the skin ...
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 ...
In aeronautics, an environmental control system (ECS) of an aircraft is an essential component which provides air supply, thermal control and cabin pressurization for the crew and passengers. Additional functions include the cooling of avionics , smoke detection , and fire suppression .
Frost ice is the result of water freezing on unprotected surfaces while the aircraft is stationary, before flight even starts. This can be dangerous when flight is attempted because it disrupts an airfoil's boundary layer airflow causing a premature aerodynamic stall and, in some cases, dramatically increased drag making takeoff dangerous or ...
