TKS de-icing fluid complies with AL-DTD406B and can be used in TKS “weeping-wings” de-icing systems. Diamond aircraft, Cirrus, Beechcraft, Cessna, Piper, Mooney, Kodiak, Hawker and many other aircrafts are equipped with the CAV-TKS system.
How does a TKS system fight in-flight icing?
A TKS system uses a TKS liquid based on ethylene glycol to coat the surface and prevent ice from accumulating. The leading edges of the wings, horizontal and vertical stabilizer are made of laser-drilled titanium panels, through which the fluid is pumped during in-flight icing conditions. A "slinger ring" may be used to distribute fluid on propellers, and a spray bar can be used to apply fluid to the windshield. The TKS fluid mixes with the ice accretion, depresses its freezing point, and allows the mixture to flow off the aircraft without freezing What are the advantages of the TKS system?
- Works for de-icing and anti-icing (curative and preventive for icing)
- High performance : the fluid runback provides total airframe ice protection
- Ease to use
What are the disadvantages of the TKS system?
Ice protection is limited to the amount of fluid (one to three hours of continuous ice protection is possible with a full tank of TKS fluid, depending on the specific system).
