Title: Explain how ice formation affects aircraft performance.
Course: Aircraft Pilot Training I (20053-I) > Section: Describing Aircraft Performance

Explanation should include the concept that icing can occur in clouds any time the temperature drops below freezing and super-cooled droplets build up on an aircraft and freeze. Super-cooled droplets are still liquid even though the temperature is below 32 degrees Fahrenheit (F) or 0 degrees Celsius (C). Explanation should also include

- the effect of ice and frost on lift, drag, and control surfaces
- carburetor ice
- aircraft systems that counteract ice.

Process/Skill Questions:

- What systems exist on an aircraft to counteract ice?
- Which conditions result in the formation of frost?
