Question: I recently moved to a colder climate and have concerns about aircraft operations, specifically early-morning departures. What are some best practices to follow?

Answer: Aviation operations in colder climates bring challenges to a pilot used to operating in warmer weather conditions. One key concept that is mentioned in the FAR/AIM for turbine aircraft that applies to piston operations is the concept of a “clean aircraft.” A “clean aircraft” means that an aircraft is free of surface contamination on lift-generating surfaces. Anytime an aircraft is parked outside on a cold winter night there is a possibility of frost. Frost is a concern, since it creates a rough surface, reducing the efficiency of lift-generating surfaces. The AIM recommends that a tactile inspection be performed whenever feasible to confirm that surfaces are clean. The Air Safety Institute produced a webinar on this topic.
