  Chapter 4. FLIGHT PLANNING › 4-3. PIREP CAUTIONS › b. No Icing Reported

  Icing Reported. An aircraft encountered icing, but the pilot did not report it. Pilot workloads might prevent a pilot from making a report, particularly when making an approach. An aircraft might also encounter icing conditions that are more serious than ... those are reported in any recent PIREPs in the given area. There are several possible reasons for this: (1) Icing conditions are extremely variable in space and time, as previously noted. PIREPs depend on the type and ice protection…
