TKS® Ice Protection

The market’s highest performing in-flight ice protection system (IPS), TKS® systems can be designed for both inadvertent (no-hazard) and Flight Into Known Icing (FIKI) conditions. It is certified for installation in over 100 different aircraft model variants and available for integration on a wide range of general aviation aircraft and unmanned aerial vehicle models in factory, or as retrofit.

The TKS® system has been designed to protect all leading edges of an aircraft, including wings, stabilizers and struts, as well as the propeller and windshield.

“I know that I am going to encounter icing, especially during the winters in Minnesota.

TKS® was a factory-installed option for this aircraft and I wanted to have an ice protection system on the airplane that would allow me to safely descend or ascend through icing conditions so that I do not have to be worried that my airplane will ice up and I find myself in a very dangerous situation.

The TKS® system is important to me because I know that I can go into clouds and have a mechanism by which my aircraft can be kept clean of ice and therefore continue to have well-functioning aerodynamic properties.”

How it works

TKS® guards the surface of your aircraft from freezing by evenly dispersing a freezing point depressant solution across the aircraft frame, preventing the accretion of ice.

The system is designed to be anti-icing but is also capable of de-icing, as TKS® fluid chemically breaks the bond between ice and frame, allowing the system to shed any accumulated ice and prevent any ice build-up thereafter.

1 Using TKS® fluid, the system depresses the freezing point of moisture encountered in flight to at least the ambient temperature or down to -76°F (-60°C).

2 Dispersed from laser-drilled titanium panels, which are mounted on the leading edges of the aircraft, the TKS® fluid mixes with supercooled water in the clouds and aerodynamic forces carry the mixture away without it adhering to the frame.

3 Retaining the original aerodynamic performance of the aircraft, factory fitted panels can be built into the original definition of the leading edge shape or retrofit to a leading edge as an overshoe.

4 The lightweight titanium panels can be mounted on wings, wing struts, horizontal and vertical stabilizers and fixed landing gear. Whilst a traditional slinger ring provides ice protection on the propeller and the windshield is protected by a spraybar.

5 This protects both the leading edge and trailing chord of the wing as fluid flows back from the leading edge under and over the entire chord of the airfoil.

6 For inadvertent systems, one metering pump is provided. FIKI-certified systems possess two metering pumps for redundancy, which can be individually selected. Two on-demand pumps for windshield protection, which can be manually selected by the pilot and run individually or collectively based on the operational selection, are also available for FIKI.

Corrosion Resistance

TKS® fluid has cleaning properties that does not harm paint finish and flushes debris from the panel holes. Unlike ground de-icing fluids which can sometimes corrode aircraft panels, TKS® fluid is non-corrosive.
