About this interactive course

This FAA WINGS credit-bearing webinar delivers expert instruction on carburetor icing in Robinson R22 and R44 helicopters. Led by Richard Mornington Sanford (45 years with Robinson) and experienced CFIs, the course covers the physics of carburetor icing, regulatory placard requirements, pre-flight detection methods, and in-flight prevention procedures. Learners will examine real-world video evidence of ice buildup in carburetors and master the temperature monitoring techniques essential for safe helicopter operations in icing-conducive conditions. Embedded knowledge checks and a comprehensive graded assessment ensure mastery of this critical safety topic.

Who is this for?

  • Helicopter pilots operating Robinson R22 and R44 aircraft
  • Commercial and private pilots seeking FAA WINGS continuing education
  • Flight instructors and CFIs teaching helicopter safety
  • Pilots in regions with high carburetor icing probability
  • Aviators pursuing advanced proficiency and accident prevention

Frequently asked

Is this course eligible for FAA WINGS credit?

Yes. This is a credit-bearing FAA WINGS webinar. Upon successful completion of the graded assessment (70% pass threshold), you will earn credit toward your FAA WINGS program. Credit integration is pre-configured; no additional credentials are required.

What is the difference between carburetor icing in the R22 and R44?

The R22 carburetor temperature probe is located upstream of the butterfly valve, where it cannot detect the most dangerous icing (downstream). The R44 probe is on the intake manifold side, providing accurate readings. This is why the R22 has a placard requiring full carb heat below 18 inches of manifold pressure.

How do I know if carburetor icing conditions exist before I fly?

Check the weather forecast and compare the outside air temperature to the dew point. A small spread (1–2 degrees) indicates high icing probability. Use the carburetor icing probability chart provided in the course to assess your specific location and conditions.

What carb heat setting should I maintain during flight?

In icing-conducive conditions, maintain approximately 15 degrees indicated on an accurate carburetor temperature gauge. This setting prevents ice formation while avoiding excessive heat that could damage the engine or carburetor.

What does it mean if RPM increases after I apply carb heat during the pre-flight check?

An increase in RPM indicates that ice was already present in the carburetor and the heat has removed it. This means the engine is now more efficient. If RPM only drops and remains low, no ice is present. Always perform this check before takeoff.

Can I prevent carburetor icing by hovering over wet grass or concrete?

No. Hovering over wet surfaces without sufficient carb heat will allow ice to form inside the carburetor. If you do this, land immediately and perform a carb heat check again before departure to ensure no ice remains.
