How did you get started in aviation? 

I started in aviation by working for a family-owned aerospace manufacturing company.

Why did you choose TKS?

My company had the requirement to travel to Duluth, Minnesota on a regular basis, as we were building turbonormalizing kits for Cirrus Aircraft. In the winter time, that resulted in flying in inclement weather and Hard IFR which sometimes involved icing.

What has TKS done for your mission?

TKS absolutely improves the utility of the airplane and the opportunity to go when needed. The system is not a FIKI-approved system; nonetheless, it has been very effective when encountering icing conditions. For the most part, it meets all of our needs for de-icing the airplane and feeling safe in doing so.

Do you have any memorable experiences with TKS?

Soon after we installed the TKS system on our Bonanza, we had the opportunity of flying at around 17,000 feet where there was a clear area adjacent to an IFR area. There was icing in the clouds of the IFR area. We were able to go in and out of the icing conditions and test the effectiveness of the TKS system. I would add that the icing conditions were significant. We found that the TKS system worked exceptionally well in dealing with the airframe icing.

Mitch S. – Cirrus SR22 TKS Testimonial

Mitch S. lives in Iowa. Where he flies covers everything east of the Rockies—from Colorado to the East Coast and Minnesota to the Gulf of Mexico. His 2004 Cirrus SR22 is equipped with a No-Hazard TKS Ice Protection System.

The Cirrus SR22 system is only available as a factory-installed option.


How did you get started in aviation? 

Flying had been a lifelong dream of mine. I finally managed to go after it in 2014, and haven’t looked back?

Why did you choose TKS?

I wanted options for flying in Midwest weather conditions. No-Hazard was a minimum requirement for me. I would love to have the FIKI system [on a newer aircraft] in the future.

What has TKS done for your mission?

Given that I have a No-Hazard system only, it hasn’t necessarily opened up new flights. But it has allowed me to work in areas and conditions with less worry.

Have you had any memorable experiences with TKS?

Funnily enough, my first flight with my new to me Cirrus we encountered unplanned icing. It was a great experience and truly amazing to see the anti-ice system in action.

Steven B. – Mooney Ovation M20R FIKI TKS Testimonial

Steven B. lives in the Northeast United States and flies in the Northeast and Southeast regions. His 2003 Mooney Ovation M20R is equipped with a Flight Into Known Icing Conditions (FIKI) TKS Ice Protection System, which he has flown since 2012.

Steve B Mooney Ovation M20R FIKI NoN

How did you get started in aviation? 

Aviation and flying have always been an interest. I took lessons after completing surgical training, and then continued to Commercial Multi-Engine Rating.

Why did you choose TKS?

Best option for Piston Single Engine Aircraft.

What has TKS done for your mission?

TKS has made the likelihood of flying (dispatch) in the fall, winter and spring much higher.

Have you had any memorable experiences with TKS?

I flew from Scranton to Pittsburgh to pick up my wife. We had planned to head south for a flight to Cuba. The weather overall in Pennsylvania was cold and rainy. I had an icing encounter each time I went through the existing cloud layer (i.e., departing Scranton, approach to Pittsburgh and departing Pittsburgh). Each time, the TKS system worked beautifully, keeping the place from gathering any significant ice.

Jim Posner – Beechcraft F33A Bonanza TKS Testimonial

Captain Jim Posner lives in the Pacific Northwest and flies throughout the United States and Canada. His 1992 Beechcraft F33A Bonanza is equipped with a No-Hazard TKS Ice Protection System, which he has flown since 2005.


How did you get started in aviation?

I started flying in the mid-1960s.

Why did you choose TKS?

I was convinced TKS was the best approach to ice protection.

What has TKS done for your mission?

TKS has reduced stress by providing a “get out of jail free” card and allows fewer canceled flights.

François G. – Cessna 182T TKS Testimonial

François G. lives in France and flies in Europe and North America. His 2006 Cessna 182T is equipped with a No-Hazard TKS Ice Protection System, which he has flown since 2007.


How did you get started in aviation? 

I started to fly 12 years ago.

Why did you choose TKS?

I need to fly extensively with the ability to exit inadvertent icing conditions.

What has TKS done for your mission?

TKS is a helpful and secure system. I have flown from Paris to New York via Iceland, Greenland and Canada. Flying over the Greenland ice cap at FL 150, we crossed an icing layer of cloud without picking up ice or losing speed.

The aircraft has also flown to Svalbard, one of the world’s most northernmost inhabited areas, located in the Arctic Ocean halfway between Norway and the North Pole.

H.C. – Beechcraft Baron FIKI TKS Testimonial

H.C. lives in the Midwest and flies from the Midwest to the Southeast. His (new to him) Beechcraft 55 Baron is equipped with a FIKI-certified TKS Ice Protection System


How did you get started in aviation? 

One day I went out to the airport for fun. Now I’m a professional pilot flying the Airbus A330.

Why did you choose TKS?

I needed an ice protection system that wouldn’t wear out when sitting outside in the Southeast. The TKS system seems like it will last longer sitting in the sun.

What has TKS done for your mission?

Before this airplane, I had a twin-engine airplane that did not have de-ice capability. TKS has allowed me a lot more reliability to get where I need to go.

Have you flown aircraft with other ice protection systems and, if so, how does TKS compare?

The hot bleed air of the Airbus A330 is probably a step up, only because I’m not buying fluid. For GA, and piston aircraft in particular, I’m very happy with how it works. The system itself—the pump, the tank, how it’s distributed, the whole operation—works nice. It also does a good job of keeping the aircraft clean.

Bonanza Install Part 5

With the plumbing and electrical wiring run, the installation moves to the windshield spraybar, the ice detection light and the prop.

The Windshield Spraybar Assembly

The windshield spraybar on the Bonanza is installed in front of the left side windscreen. The spraybar itself is a stainless steel tube with 12 holes drilled to jet TKS fluid onto the windscreen. The spraybar is bent to follow the rivet line of the lower windscreen.

1. Windshield spraybar mounted.

A deflector is riveted over the spraybar to ensure the fluid flows properly in flight.

2. Spraybar deflector assembly positioned.

3. The deflector is riveted and bonded prior to paint.

The windshield spraybar is not running when the rest of the TKS system is active. The spraybar has its own dedicated pump. When the spraybar is activated from the control panel, the fluid will spray for 4 seconds and stop automatically. After a 4 second delay, the spraybar may be activated again if necessary.

5. The windshield spraybar in action.



The Ice Detection Light Assembly

The ice detection light is installed in the lower left cowling in order to allow illumination of the left wing. The ice detection light bracket holds a light bulb which is angled to the middle section of the leading edge of the wing.

6. Ice detection light installed in cowling.

7. External view of the ice detection light assembly.


The TKS Slinger Ring Assembly

A predetermined flow of TKS ice-protection fluid is metered into a propeller slinger ring through an injection nozzle. Once the fluid enters the slinger ring, centrifugal force directs the fluid to the outermost portion of the ring. Holes mounted in the slinger ring provide a path for the fluid to travel, ultimately coming out of a tube positioned on the leading edge of the propeller. The propeller blade leading edges are fitted with a channeled boot, providing a flow path for the TKS fluid. The fluid passes out of the feed tube and onto the ribbed boot. Centrifugal force directs the fluid outward.

8 Prop boot. The ribs channel fluid along the prop blade.


The manufacturer of the prop will determine the build of slinger required.

A McCauley prop will have a slinger ring which is bonded to the prop hub. Scoops mounted in the slinger pick up the fluid and deliver it to the prop blades.

A Hartzell prop will have a slinger ring which is mounted in a stand-off position. Three hollow bolts are used to mount the slinger to the prop hub. The bolts pick up the fluid and deliver it to the prop blades.

MT manufactured props must have a MT manufactured slinger ring installed.

The propeller blades

After the propeller has been removed from the aircraft and placed in the prop shop, the prop blades are prepared for the TKS boot installation. If the aircraft was previously equipped with thermal propeller protection, the heated boot elements and all adhesive residues are removed. The prop blades are then cleaned and the area where the TKS boots will be installed is prepared.
