Time to think about carb ice!
It is time to think about CARB ICE! Actually any time is time to think about carb ice. So here is a simple reminder:
According to FAA Advisory Circular 20-113, Pilot Precautions and Procedures to be taken in Preventing Aircraft Reciprocating Engine Induction System and Fuel System Icing Problems, "Heat should be applied for a short time to warm the induction system before beginning a prolonged descent with the engine throttled and left on during the descent. Power lever advancement should be performed periodically during descent to assure that power recovery can be achieved."
Remember the basics like proper handling of carb heat. Avoid letting your glass cockpit and portable "gee-whiz" gadgets distract you from taking proper care of your engine, you aircraft and your flight.
