Over a period of years, the Cirrus Aircraft team engineered the TKS anti-icing de-icing option into a full system required for flight through known icing. The Cirrus FIKI system has additional and upgraded components over the previous basic inadvertent ice protection systems.
The industry term is Flight Into Known Icing or “FIKI.” But Cirrus emphasizes their intent for use of the system is not to allow you to fly into ice but to give you more time and added margins to escape ice should you encounter it.
- In 2009, Cirrus announced the FIKI system and priced it as a $24,500 option.
- In 2007, Cirrus introduced the redesigned G3 wing with enhanced inadvertent ice protection.
- In 2002, Cirrus released basic inadvertent ice protection as an option on Generation 2 planes.
Summary Cirrus Aircraft TKS De-Icing Systems
|Year||Generation||TKS System||TKS Tanks||Gallons||Normal|
|2007||G3||Inadvertent Icing||1||3.5||80 minutes|
|2002||G2||Inadvertent Icing||1||2.9||60 minutes|
The Generation 2 (G2) Cirrus TKS system operating time in normal mode is 60 minutes but while in “maximum” setting it’s limited to about 30 minutes.
The Generation 3 (G3) Cirrus de-icing system was expanded to cover the entire wing. It’s TKS titanium panel begins at the wing root and extends from there to the wing’s outer edge. Normal mode should be selected when conditions for icing are encountered and before ice accretion. The Cirrus G3 TKS system operating time in “normal” mode is up to 80 minutes. If ice has accreted to flight surfaces the TKS maximum mode should be selected. The TKS operating time while in “maximum” mode is up to 40 minutes.
In 2009, FIKI became the standard Cirrus TKS system. Pilot’s have an enhanced system display on the MFD which shows you the amount of fluid in each tank, and available de-icing time at the three flow rates (normal, high and maximum). The system will even display aircraft de-icing range available based on the operating rate selected.
There’s more fluid capacity in the FIKI to address the hazard of ice. Each wing has a 4-gallon TKS tank that when filled gives the system up to 2.5 hours of operation. Automatic cycling between the tanks will keep the fluid levels roughly even. The FIKI system includes backup pumps.
