Assertion (A): Freezing drizzle is regarded as an especially hazardous icing condition.
Reason (R): Its large droplets run back beyond the protected leading edge before freezing.

  • A.Both A and R are true, and R is the correct explanation of A
  • B.Both A and R are true, but R is not the correct explanation of A
  • C.A is true but R is false
  • D.A is false but R is true

Answer: A

Both are true and the reason gives the danger, and de-icing systems protect only the forward surfaces. Ice forming behind them disrupts the airflow where nothing can remove it. Certification standards now address these larger droplet sizes.
