Carburetor Icing in Detail with Richard Mornington-Sanford

How long before Carb Icing occurs? Richard says, The answer dependent on a few key criteria: Accuracy of the CATG How serious the conducive carb icing conditions are The HP being used as this direct affects the butterfly angle in the carburetor What platform…Beta or Beta II The growth you see on the icing presentation was circa 3 mins at MCP. It was a test bed film and if I remember the carburetor icing was encouraged a bit. I would say to err on the side of safety and say that it would start immediately! The same would be recommended if flying an R44. With the R22 as I said you need 15deg C indicated on a known accurate gauge. The R44 just out of the yellow on a known accurate gauge.
