Promoting the safe enjoyment of aviation for pilots, aircraft builders and enthusiasts.
Carburetor ice can form even at higher ambient temperatures, potentially as warm as 100°F (38°C), due to significant temperature drops in the carburetor throat. However, it is most common when temperatures are under 70°F (21°C) and humidity exceeds 80%. Regular checks of carburetor heat are crucial for engine operation.
Last week featured harsh weather, limiting flying opportunities except for one successful trip. Work included servicing two Diamond DA-42 Twin Stars and an Aztec for avionics upgrades, where a new method using solder sleeves for shielded wire installation improved efficiency and appearance, replacing more time-consuming traditional techniques.
Aircraft operation is significantly endangered by carburetor icing, which is often unnoticeable to pilots until power loss occurs. Conditions for icing commonly arise at temperatures between 20°F and 65°F with high humidity. Preventive measures include maintaining appropriate air temperatures and monitoring humidity to mitigate the risk of icing effectively during flights.
The past month featured enjoyable weather and a successful Annual CUFC Banquet and Auction, raising $850 for the COPA Emergency Action Fund. The author shared insights on carburetor ice, detailing its three types: fuel vaporization, impact, and throttle ice, highlighting the importance of carburetor heat to mitigate these issues.
