Fall Flight Checks: Preparing Your Aircraft for Cooler Weather

Why Seasonal Prep Matters

As summer gives way to autumn, flying conditions improve in many ways—smoother air, cooler temps, and stunning scenery. But the change of seasons also brings new maintenance and safety challenges. Pilots and owners should take time to prepare their aircraft for cooler weather to ensure safe, reliable flying all fall long. Make sure you partner with your A&P and CFI to fully discuss how to be a ready pilot and a ready aircraft.

It is always important to make sure your aircraft is properly maintained before flying.

Engine and Systems Readiness

• Oil Change: Switch to a multi-grade oil suitable for cooler weather if you haven’t already.

• Carburetor Heat Checks: Cooler temps mean higher risk of carb ice—ensure the system is working properly.

• Pre-Heat Equipment: If you expect cold mornings, test or invest in an engine pre-heater to reduce wear.

• Battery Condition: Cold weather drains weak batteries—check voltage and replace if needed.

Airframe and Avionics

• Pitot-Static System: Inspect for leaks or moisture, which can freeze in colder temps.

• Cabin Heating: Test cabin heaters for both comfort and safety.

• Lighting: Shorter days mean more night ops—verify that all navigation, landing, and panel lights are functional.

• Avionics Updates: Ensure databases and software are current before the busier flying season.

Seasonal Safety Considerations

• Morning Frost and Fog: Expect early morning delays and plan flights accordingly.

• Carb Ice Awareness: Stay alert during low-power phases of flight, especially descent.

• Wildlife Hazards: Deer and birds are more active around runways in the fall—scan carefully on takeoff and landing.

• Cold Fronts: Weather can shift quickly—use EFB tools for real-time updates.

Pilot Preparedness

Just as your airplane needs prep, so do you:

• Carry extra layers in case of diversion.

• Review cold-weather emergency procedures.

• Brush up on night flying skills to match earlier sunsets.

Final Thoughts

Fall offers some of the best flying of the year, but only if your aircraft is properly maintained for the season. By completing a thorough fall flight check, you’ll protect your investment, ensure safer operations, and enjoy the season to its fullest.
