At what temperatures can carburetor ice form depending on relative humidity?

• A. -10 to 0 Celsius
• B. -7 to 21 Celsius
• C. 0 to 15 Celsius
• D. -5 to 10 Celsius

Answer: (B)

Carburetor ice can form when the temperature is between -7 to 21 degrees Celsius, primarily depending on relative humidity levels. The critical factor for carburetor icing is the temperature and the moisture content in the air. When the air passes through the carburetor, it experiences a pressure drop and cooling, which can lead to condensation in humid conditions. At temperatures above 0 degrees Celsius, there is a significant likelihood of carburetor ice formation if the relative humidity is high. This formation can occur even at temperatures that might not seem particularly cold, as long as the conditions favor it. The specific range of -7 to 21 Celsius encompasses a scenario where relative humidity can be high enough for ice to form, making it the correct choice for understanding the conditions that promote carburetor icing in aviation.
