Understanding Flight Safety by Time of Day

Many travelers feel nervous about flying and often wonder if certain times of the day are safer than others. While air travel remains one of the safest ways to get around, research shows that commercial flights have doubled in safety with each passing decade over the last 50 years. In fact, 2023 recorded the lowest fatality risk in commercial aviation history.

Despite these improvements, it is still important to consider all factors that might affect flight safety. This article examines how time of day impacts flight safety by analyzing accident data, weather conditions, air traffic levels, and pilot fatigue.

Flight Accidents and Time of Day

There is no clear data on commercial flight accidents based on the time of day. However, general aviation statistics provide useful insights. According to the Aircraft Owners and Pilots Association (AOPA), nighttime accidents in private aviation mostly happen during mid-flight, while daytime accidents are more common during landing. This suggests that low visibility and pilot tiredness may contribute to nighttime crashes.

Takeoff and landing are the riskiest moments of any flight. In private aviation, 84% of nighttime crashes occur in clear weather, while 14% happen in poor visibility conditions. Among these, over 67% result in fatal outcomes. However, private aviation involves smaller planes, and the risk factors may differ from commercial flights. More research is needed to confirm if similar trends apply to airline travel.

Research shows that up to 80% of all plane accidents are caused by human mistakes. Among these, pilot errors make up 53%, while mechanical failures account for 21%, and bad weather contributes to 11%.

Weather and Air Traffic Impact on Flight Safety

Weather plays a major role in flight delays and safety. Studies show that weather-related issues cause about 75% of all flight delays of more than 15 minutes in the U.S. Airports in New York, Chicago, and San Francisco experience the most weather-related disruptions. The type of weather causing delays changes throughout the year. For example, winter storms led to the highest number of delays at New York airports in 2022.

Severe weather conditions such as strong winds, fog, and thunderstorms can reduce airport capacity, force runway closures, and lead to cancellations. Snowfall can create dangerous runway conditions by lowering visibility and making the surface slippery.

Air traffic congestion also plays a role in flight safety. Traffic levels change throughout the day based on work hours, special events, weather conditions, and airport operations. Although there is no exact data on peak congestion times for flights, it is logical to assume that mornings and evenings—when most people commute—are the busiest periods.

Pilot Fatigue and Alertness

Pilot fatigue is a serious safety concern in aviation, as it can slow reaction times and affect decision-making. Several factors contribute to fatigue, including long work hours, shifting sleep patterns, and inadequate rest. Studies show that exhaustion can cause reduced concentration, memory lapses, and slower responses.

Research on short-distance airline pilots found that both early morning and late-night flights can reduce performance. Pilots on late-night flights reported higher fatigue levels, while early-morning pilots experienced slower reaction times due to lack of sleep. Morning flights may require pilots to wake up much earlier than usual, which disrupts their natural sleep cycle and leads to tiredness.

Another study found that pilots are most likely to experience brief, involuntary sleep episodes (microsleeps) during cruising but remain most alert during takeoff and landing.

To manage fatigue, pilots use various strategies, including:

• Sleeping the same amount of time they usually do at home
• Taking short naps (no longer than 45 minutes) to avoid grogginess
• Timing meals to avoid long periods without food
• Balancing work duties with rest breaks

Airline and Aircraft Safety Factors

While this article focuses on time of day, it is important to note that airline policies and aircraft type also affect flight safety. Airlines have different maintenance standards and safety practices, while aircraft models vary in design and features. Factors such as plane age, service history, and safety culture all play a role in reducing risks.

Additionally, airport location and design can impact safety. Some older airports, like Chicago Midway, were originally built for smaller planes and are now in crowded areas, making it difficult to meet newer safety standards. For instance, in 1999, the FAA required runways to have buffer zones of at least 150 meters on each side and 300 meters at the end, but many older airports do not meet these guidelines.

Final Thoughts: What Is the Safest Time of Day to Fly?

Determining the safest time to fly is complex. While general aviation data suggests night flights may pose higher risks due to visibility issues, this may not fully apply to commercial airlines. Weather patterns, air traffic, and pilot fatigue also vary throughout the day, making it difficult to pinpoint a single “safest” time.

However, based on the research, travelers can take precautions:

• Check weather conditions: Avoid flying during stormy seasons or peak thunderstorm hours.
• Be mindful of pilot fatigue: Pilots are typically more alert during mid-morning and early afternoon.
• Choose reliable airlines and aircraft: Research airline safety records and select newer, well-maintained planes.

While no time of day guarantees complete safety, being aware of these factors can help passengers make better travel decisions. Staying informed and prioritizing safety measures will ensure a smoother and more secure flight experience.
