July 19 - Now that the TKS ice protection system has been installed on the AOPA Sweepstakes Bonanza, neither rain, hail, sleet nor snow should keep the Beech Bonanza from its appointed rounds.
During icing conditions, the lucky winner of the Bonanza will be able to turn on the pumps of the TKS ice protection system, which will distribute an ethylene glycol/isopropyl alcohol-based fluid to the propeller, windshield, and wing and stabilizer leading edges.
This fluid drastically lowers the freezing point of any liquid it encounters, loosening ice on the airframe and allowing the relative wind to carry it away. When turned on prior to ice accumulation as an anti-icing system, the fluid prevents the formation of airframe ice.
The fluid is spread across the wing leading edges by thousands of tiny laser-drilled holes in titanium wing and stabilizer leading edges. These are bonded onto the airframe during system installation.
Aerospace Systems and Technologies Inc. holds STCs for the installation of the TKS ice protection system on numerous high performance general aviation single- and twin-engine airplanes. For many general aviation airplanes, the TKS system is the only de- and anti-icing system available.
