Now reflect on all three primary impacts of weather on aviation.  How would you quantify the impact of weather on aircraft performance for this case? 单项选择题

Moderate icing is forecast along your route, and the freezing level is very close to your planned altitude, plus the ceiling is getting lower with time. While you should not be flying into clouds because you are VFR only, there is a high likelihood of accidentally getting into clouds, which would be very dangerous (high risk).

While moderate icing is expected along your flight path, the icing threat begins above your planned flight level. The impact of icing on aircraft performance is minimal (low risk).

Moderate icing is forecast along your route, but a Cessna 172 should be able to fly in moderate-severe icing as long as the bleed air is circulating through the wings properly (low risk).
