Corvalis, con’t.ANTI-ICE SYSTEM -TKS ON CARAVANSThe power plant didn’t escapeupgrades, either. It now comeswith a five-year parts and laborwarranty and a new starter thatimproves turnover.Clark knows the characteristicsof Corvalis owners and the TTX ®target market: “They are pilotswho want to be at 25,000 feetflying 300 knots. They are loyaland love their airplane.”Owner’s Experience:The Cat’s MeowJerry Shapiro, a dentist inSouthhampton, Pa., nearPhiladelphia, purchased a newCessna Skylane in 2005, butthen,” I wanted to go faster,so I bought a Corvalis.”“I tested every aircraft therewas. I wanted to have thefinest,” says Shapiro, who is6’ 2”. “Somebody told me to trythe Corvalis, and it was roomy.It was incredible.”Since 1999, he’s flown hundredsof patients on sightseeing tripsas a way to market his practice.New York City and the JerseyShore are popular jaunts. Twoyears ago, he and a pilot-patienttook three weeks and put theCorvalis’ speed and range towork on a dream trip around theUnited States. “I landed everyplacecool,” he says. Along theway, the Corvalis carried aJerry Shapiroflying in hisCorvalis.beacon allowing patients andothers to track his progress.“I just love the Corvalis. It’sperformed for me. At thehighest airports it was like sealevel. It’s quiet and smooth.Even when it’s turbulent forother aircraft, I don’t feel it inmine,” he says. “My plane isthe cat’s meow.”Cessna has refined the preflightoperational test for the TKS anti-ice systeminstalled as an option on some CaravansThe initial revision to the POHsupplement requires thesystem to be operated fourminutes in backup mode topurge the panels. This assuresonly TKS fluid is present in thepanels at departure. The revisionalso requires all panels areobserved for even flow orwetting of the panel activesurface during the purge. Thisfour minute purge is to beperformed after any grounddeicing operations.Experience has shown thatatmospheric moisture, such asrain and ground deice fluid, canpenetrate the active surface ofthe TKS panels and raise thefreezing point of the fluid within.This elevated freezing point canreduce initial system functionin-flight when icing conditionsare encountered.When surface conditions makeit necessary to apply Type II, III,or IV deice fluid to increase holdover time, after the initial deiceand preflight activities arecomplete, the TKS system shouldbe operated in the Backup Modeduring the application. Thisreduces the possibility of grounddeice fluid contamination ofthe panels.The initial revision’s requirementfor even flow may not be metwhen surface temperatures areabove 50 degrees Fahrenheit. Thissystem characteristic is due to thereduction in viscosity of the TKSanti-ice fluid at elevated temperatures.The second revision tothe POH supplement requires thesystem to be operated in BackupMode initially to check operationof the Warn Light and then MaxMode to provide the increase influid volume to more fully wet outthe active area of the panels. Atsurface temperatures above 80degrees Fahrenheit, flow may notbe present on the upper portionof the vertical stabilizer panel andthe outboard upper areas of thewing panels during operation inMax Mode. This is a systemcharacteristic and is not causefor a maintenance action.Corvalis TTX ® by the NumbersMaximum Cruise Speed235 ktasMaximum Range 11,250 nmTakeoff Distance (S.L., ISA, MTOW) 2 1,900 ft.Landing Distance (S.L., ISA, MLW) 2,640 ft.Maximum Operating Altitude 25,000 ft.Maximum Climb Rate (Sea Level) 1,400 fpmAvionics Intrinzic (Garmin G2000)Engine330 hp Continental TSIO-550-CFuel capacity102 gallons145 minute fuel reserves, 45% power @ 25,000 ft.2Distance to 50 feet above the runwayThe flow during high temperatures.
