Analyze the implications of at least three of the conditions listed in K3a through K3l, using actual weather or weather conditions provided by the evaluator.

Bottom line

Review the type, location, and movement of weather systems and/or air masses that might affect the proposed flight by using surface analysis, weather depictions, radar summary, and constant pressure charts. PIREPs are a valuable source of in-flight information regarding en route conditions including turbulence, icing, visibility, temperature, and winds aloft.
