Cold-Weather Flight Operations

When living in a locale with winter weather cold enough for clichs and wanting to commit aviation, there are three alternatives for coping: 1) Borrow a snowplow and drive south-when someone asks, "Whats that?" stay there and fly; 2) subdue the urge (as did 1920s barnstormers, realizing the oversupply in warmer climes would cause them to starve), secure the airplane, rent a hotel room and hibernate after contracting with a bootlegger for regular deliveries; or, 3) keep flying. While not expressing a preference, our habit has been to continue flying while modifying our behavior. Among the changes is realizing winter means more than cold: It means fewer hours of daylight, so more-risky night flying also is likely. It means everything takes longer to accomplish, be it as mundane as putting on appropriate flying attire or as complex as readying a tied-down airplane for flight. It means hurrying means radically increasing the chance of making a small mistake and, in winter, small mistakes are far more likely to have a fatal outcome than in summer.

Key Takeaways:

• Winter flying introduces unique and heightened risks beyond just cold, including reduced daylight, airframe icing, poor visibility, and slippery surfaces, making small errors potentially fatal.
• Thorough aircraft preparation is critical, involving specific modifications like winterization kits, removing wheel pants, and using a reliable carbon monoxide detector, alongside essential engine preheating below 40°F, ideally with an electrical block heater.
• Pilots must adapt operational procedures across all flight phases, from an unhurried pre-flight (never ignoring issues like a non-draining fuel quick drain) to cautious engine starts, slow taxiing, careful takeoffs with attention to surface conditions, and vigilant landings, especially concerning "flat light" conditions and potential frozen brakes.
