| Just a quicky regarding carb icing..
The air temp doesn't have to be cold in order for this to happen. It can happen in summer just as easily. What causes it is high humidity. As the air rushes through the carb's venturi it speeds up - and thus it cools rapidly. If its moisture content is high it can freeze. (The smaller the carb's venturi, the faster the air rushes through it and the cooler it becomes. Hence, icing is more likely to occur when the venturi/throttle is closed)
(Piston-engined aircraft flying in cloud have carb heaters in order to lessen the chances of this happening) |
