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.
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 .
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 ...
In 2011, the ice detection system was found to be defective due to the use of counterfeit components; allegedly these parts were poorly refurbished and sold to subcontractor BAE Systems as new by a Chinese supplier.

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.
Other aircraft systems typically monitored by EICAS are for example hydraulic, pneumatic, electrical, deicing, environmental and control surface systems. EICAS has high connectivity & provides data acquisition and routing. [2] EICAS is a key function of a glass cockpit system, which replaces all analog gauges with software-driven electronic ...
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.
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 ...
