PPG Industries’ aerospace transparencies business has been awarded a contract by Cessna Aircraft Co. to develop and produce all-glass heated cockpit windows for the new Citation Columbus business jet. The windshields and side cockpit windows for the Columbus are expected to be similar to those PPG supplies for Cessna’s Citation VII, Citation X, Citation Excel, Citation Sovereign, and Citation CJ4 business jets. The cockpit windows for Columbus will have three plies of PPG's Herculite II glass, which is chemically tempered for high strength at light weight, and the Nesatron heating system. The windshields will also have Surface Seal hydrophobic coating for rain clearing and an antistatic coating to redirect static discharge, enhancing the life of the Surface Seal coating. Using Surface Seal coating on windshields enables Cessna to pursue certification without wipers on its planes. The Citation Columbus is expected to gain full certification in 2013 and to enter service in 2014.
