The recommended resource for determining the freezing level and areas of probable icing aloft are inflight aviation weather advisories. These advisories provide up-to-date information on current weather conditions, including critical details about icing, turbulence, and other in-flight weather hazards. They are specifically designed to assist pilots during flight by offering timely alerts about significant weather phenomena, which helps in making informed decisions about altitude and routing to avoid hazardous conditions.

Weather maps, while useful for getting a general overview of weather patterns, do not provide the specificity about icing levels and freezings that the inflight advisories do. Terminal aerodrome forecasts are primarily focused on weather conditions at specific airports and may not encompass the broader, more complex atmospheric conditions that impact icing levels at higher altitudes. Pilot reports (PIREPs) offer real-time observations from other pilots, which can be valuable but may not systematically cover the comprehensive information about icing levels and freezing altitudes present in the inflight aviation weather advisories.
