When analyzing the benefits of the Zonal Drying™ System in operation, it has to be pointed out that all benefits cannot easily be related to Dollars and Cents, some benefits are also connected to passenger comfort and aircraft reliability. The main improvements experienced when operating an aircraft with the Zonal Drying™ System installed are: - Increased Aircraft reliability - Reduced aircraft weight - Reduced fuel burn - Lowered emissions - No water or ice in insulation blankets - Reduced change rate of insulation blankets - Sustained insulation blanket performance - No build up of fungus and bacteria in insulation blankets - No "rain in plane"- No wet seats or carpets - No brown or fogging windows - No frozen emergency exits or frozen emergency slides - Less airframe corrosion - Less rectifying work connected to corrosion - Less electrical failures or arcing - Less rectifying work connected to electrical failures or arcing - Sustained or increased residual value of the aircraft However the main issue is that; having uncontrolled water pouring around in an aircraft close to electrical wirings, electrical connectors and computers is not in line with operating an aircraft in a safe environment.
