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.
The author experienced high oil temperatures in their Cavalier aircraft after engine installation, initially measuring 205-220 degrees F. They replaced the oil cooler and constructed a shroud to improve airflow, reducing temperatures to 170-195 degrees F. Following an investigation, they confirmed the installation of a necessary Vernatherm, enhancing engine cooling performance.
September was filled with enjoyable flying experiences, including a successful "Fly for Pie" event that raised $305 for the COPA Freedom-to-Fly Fund, featuring various aircraft. Despite weather challenges, the postponed COPA for Kids day proceeded well. Additionally, work resumed on the Buttercup plane, tackling landing gear installation difficulties.
The author reflects on a vacation, highlighting their participation in the CRUFC 2010 Air Adventure Tour and subsequent work on aircraft maintenance. They faced engine oil temperature issues attributed to a plastic tub obstructing the air valve but eventually resolved the problem. The trip was ultimately successful and enjoyable, bolstered by modern technology like an iPhone.
The year ended with a memorable flying experience over the Kananaskis Valley during a visit from the author's parents. After a clear Boxing Day, the author and friends enjoyed a smooth flight, overcoming oil temperature regulation challenges with a new adjustable air intake for the engine. The joyful day concluded with successful flight procedures and exploration.
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.
Aircraft performance is greatly influenced by density altitude, impacting take-off distance and rate of climb. Manufacturer claims are based on standard conditions, but real-world factors like temperature and altitude can double take-off distance and reduce climb rates. Other considerations include airfield conditions, wind, and angle of climb. Understanding density altitude is crucial for maximizing aircraft performance.
