Your Lancair is equipped with simple air intake scoops for cabin ven-tilation. The vents are located at the pilot’s left knee and co-pilot’s right knee.Heating. Cabin heat is provided by means of an intake system using air warmed bypassing over/thru a heat exchanger where exhaust gases are used as the heat source.This air-to-air heat exchanger provides air which is either dumped overboard, orinto the cabin. Due to the potential of a leak from the higher pressure exhaust gasescontaining Carbon Monoxide (CO) into the fresh air side of this heat exchanger, itis necessary to inspect the structural integrity of the unit periodically. Initial opera-tion of the system for the winter months should always include such an inspection.A monitoring system should be considered for the cabin air. These simple deviceschange color upon exposure to CO. They are quite cheap, and excellent insuranceagainst the effects of this odorless, colorless, and deadly gas. Optionally install anelectric CO monitor available through Lancair Avionics.COLD WEATHER OPERATIONSPREFLIGHT INSPECTIONSWinter preflight inspections of the aircraft need to account for the accumulationof frost or ice on the exterior of the aircraft. The Lancairs with their extraordinarysmoothness can suffer markedly from the effects of such accumulations as theyutilize laminar flow airfoils. These effects result in significantly higher drag of theair-frame and wings as well as reduced lift and increased weight of the accumulation.Once these deposits have been removed (preferably by warming in a hangar) thepreflight should include special emphasis on freedom of control movements.
