COLD WEATHER OPERATIONS

As temperatures drop, the flying doesn’t stop, but cold weather can introduce challenges that require extra preparation and awareness. Winter operations demand good decision making on the ground long before the engine starts.

Preflight: I know it’s cold but take your time!

Cold weather preflights take longer, and for good reasons. Frost, snow, or ice on the aircraft is never acceptable.  A thin layer of frost can significantly reduce lift and increase stall speed. Always remove all contamination from wings, tail surfaces, and control surfaces before flight.

Pay close attention to engine oil levels and viscosity. Cold temperatures can thicken oil, making engine starts harder (especially in N3819L). Use proper cold start procedures and never rush the warmup. ALWAYS refer to the aircraft’s POH for cold starting operations.  Follow the checklist procedures and avoid excessive cranking. Once started, allow the engine to warm gradually. High RPM on a cold engine can cause unnecessary wear or damage.  Primer is your friend when starting a cold engine!

In Flight: Performance Changes

Cold, dense air can improve aircraft performance, shorter takeoff rolls and better climb performance, but don’t let that create complacency. Weather conditions can change quickly in winter, and visibility may deteriorate faster than expected due to haze, snow, or low ceilings.

Carburetor icing is still a risk in cold weather, especially in certain temperature and humidity ranges. Be proactive with carb heat when conditions are favorable for icing, once again, refer to the POH for your aircraft about when to apply carb heat.

Weather and Decision Making

Always check weather thoroughly, ask an instructor when in doubt, and remember that canceling a flight is often the smartest decision you can make.

Dress appropriately. Even on a clear day, an off airport landing in cold weather can quickly become a survival situation. Wear layers, and clothing suitable for the environment you are flying over, not just the ramp.

Cold weather flying can be rewarding and beautiful, but it demands respect. Take your time, follow procedures, and never hesitate to ask questions. Smart winter operations start with preparation, and end with a safe return to the ramp.
