Adverse weather considerations for performance on takeoff (e.g., snow, ice, gusting crosswinds, lowvisibility).
Bottom line
Aircraft that have ice, snow, or frost on their surfaces must be carefully cleaned prior to beginning a flight because of the possible airflow disruption and loss of lift. The most critical conditions of takeoff performance are the result of some combination of high gross weight, altitude, temperature, and unfavorable wind.
