Thorough flight preparation is crucial in order to recognise the dangers of winter weather. This includes a comprehensive weather briefing, which is easily accessible thanks to the internet and specific services such as METAR and TAF. It is also important to pay attention to local conditions and the state of the runways, which can be done by contacting the aerodrome. Particular attention should be paid to the Low-Level Significant Weather Chart (SWC) and SIGMET/AIRMET warnings, which provide information on potential weather hazards along the flight route.
The greatest danger in winter flight operations is icing. Although clear, cold air generally contains little moisture and therefore the risk of icing in VFR operations is low, entering precipitation zones can lead to severe icing. The most effective measure against icing is to descend into warmer layers of air. If the aircraft is iced up, the approach should be made at increased speed and, if possible, without flaps, as icing of control surfaces can considerably restrict controllability. In such cases, an approach to an aerodrome with a long runway is recommended.
