categorical terms (for selected zones only). • Categorical outlook (VFR, MVFR, and IFR) for 12 to 18 hours. 3. Icing and Freezing Level: A description ... expected icing conditions, including the following elements: • AIRMET information for icing and freezing precipitation. • Icing not meeting SIGMET or AIRMET criteria during the six-hour to 12-hour period. • Freezing level. • If no significant icing is forecast, NIL SIG will…

intended to inform all pilots, especially VFR pilots and operators of sensitive aircraft, of potentially hazardous weather phenomena. AIRMETs contain details about IFR, extensive mountain obscuration, moderate turbulence, strong surface winds, moderate icing, and freezing levels. AIRMETs are intended ... Over the CONUS, AIRMETs are also available on equipment intended to display weather and other non-ATC-related flight information to pilots using the FIS-B. In Alaska and Hawaii, AIRMETs are broadcast on air traffic frequencies. AIRMETs are issued…

icing is detected, a pilot should do one of two things, particularly if the aircraft is not equipped with deicing equipment; get out of the area of precipitation; or go to an altitude where the temperature is above freezing. This ... always be a lower altitude. Proper preflight action includes obtaining information on the freezing level and the above freezing levels in precipitation areas. Report icing to ATC, and if operating IFR, request new routing or altitude if icing will…

inadvertent icing encounter, it is important the pilot act to prevent additional ice accumulation. Regardless of the level of anti-ice or deice protection offered by the aircraft, the first course of action should be to leave the area ... altitude where the temperature is above freezing. Pilots should report icing conditions to ATC and request new routing or altitude if icing will be a hazard. Refer to the AIM for information on reporting icing intensities. Fog Instrument pilots must…
- Chapter 4. FLIGHT PLANNING › 4-1. PREFLIGHT PLANNING INFORMATION
Information (AIRMET), and significant meteorological information (SIGMET) provide general information on forecasted inflight icing. Winds aloft forecasts also provide information to determine the approximate freezing level. The graphical CIP and the FIP combined with text based forecasts, provide adequate information…
