Why skipping just one step can start a chain of errors
It’s minus five degrees on the ramp, the wind is cutting through your gloves and your pen won’t write. In these conditions, it’s tempting to speed things up - and that’s when checklist drift creeps in.
Checklist drift is the gradual - often unconscious - habit of skipping or rushing checklist items because conditions make them uncomfortable or seem “less urgent.” In cold weather, the risk spikes.
❄️ Why Cold Changes the Game
Frozen fingers make fine motor tasks slower and more frustrating.
Crews shorten callouts or skim over items to get back inside quickly.
Ramp noise and winter clothing can make communication harder.
Tasks that look complete (like doors closed or covers removed) may not be verified properly.
The danger? Small oversights in pre-flight or post-flight checks can snowball into operational safety issues.
Preventing Checklist Drift
🧠 Mindset
Cold isn’t an excuse; cold is a reason to be more methodical. The harsher the conditions, the greater the need for discipline.
👥 People
Pair up effectively. Cross-check each other’s items even more rigorously when working in cold, dark and/or noisy conditions.
⚙️ Equipment
Use gloves that allow dexterity for switches and writing. Keep checklists laminated or in cold-resistant covers to prevent sticking or tearing.
📋 Compliance
Follow the checklist as written. Avoid combining or skipping steps, even if they might seem obvious.
⚠️ Risks
Unlatched panels.
Pitot covers left in place.
Incomplete de-icing inspections.
Mis-set controls.
📚 Learning
In January, a Safewings crew skipped a full control surface check because “the gust lock was in” and it was “too cold to stay outside.” On taxi, the elevator felt heavy. The gust lock had not been fully disengaged. The aircraft returned to stand. A safe ending, but a delayed departure and a lesson learned.
Cold weather makes you hurry. Your checklist exists to make you slow down and be methodical - always.
