Inclement weather like rain or snow can cause flight delays and cancellations. But can planes still take off in rainy conditions? Keep reading to learn everything you need to know about planes taking off in the rain.

If you’re short on time, here’s a quick answer to your question: Yes, commercial airliners are designed to operate safely in rainy conditions. While heavy rain may cause delays, planes routinely take off and land during light to moderate rainfall.

How Rain Affects Takeoff

When it comes to aviation, safety is always a top priority. One factor that can greatly impact the takeoff process is rain. While planes are designed to withstand various weather conditions, rain can still pose certain challenges. Let’s take a closer look at how rain affects takeoff.

Reduced Visibility

One of the main concerns during takeoff in rainy conditions is reduced visibility. Rainfall can create a misty or foggy atmosphere, making it difficult for pilots to see clearly. This can be especially problematic during critical phases of takeoff, such as when the plane is gaining speed on the runway or when it’s lifting off the ground.

Reduced visibility can increase the risk of accidents, which is why pilots rely on their instruments and follow strict protocols to ensure a safe takeoff.

Wet Runways

Another issue that arises when it rains is the condition of the runway. Wet runways can affect the plane’s performance during takeoff. When the runway is wet, the tires of the aircraft have less grip, which can lead to longer stopping distances and reduced acceleration.

This means that the plane needs more runway length to reach the required takeoff speed. Pilots take these factors into account and adjust their calculations accordingly to ensure a successful takeoff.


Rain often comes with wind, and crosswinds can pose a challenge during takeoff. Crosswinds are winds blowing perpendicular to the runway, and they can cause the plane to drift off its intended path during takeoff.

This can make the takeoff procedure more challenging for pilots, as they need to compensate for the wind and maintain control of the aircraft. Airports have specific procedures in place to deal with crosswind conditions, and pilots receive specialized training to handle such situations safely.

Aircraft Design Features for Rain

When it comes to flying in inclement weather, one question that often arises is whether planes can take off in the rain. While rain can pose certain challenges for aircraft, modern aircraft design incorporates several features to ensure safe and efficient operations even in rainy conditions.

These design features include windshield wipers, anti-icing systems, and grooved runway tires.

Windshield Wipers

Just like cars, airplanes are equipped with windshield wipers to maintain visibility during rain showers. These wipers are specially designed to withstand the high speeds at which planes travel. They are typically made of sturdy materials and have multiple blades to efficiently clear water from the windshield.

Windshield wipers enable pilots to have a clear view of the runway and other aircraft, ensuring safe takeoffs and landings.

Anti-Icing Systems

Another crucial feature in aircraft design for rain is the anti-icing system. As raindrops fall onto the aircraft’s surfaces, they can freeze and create hazardous ice formations. To prevent this, aircraft are equipped with anti-icing systems that heat the surfaces where ice is most likely to form, such as the wings, tail, and engine inlets.

This prevents ice accumulation and ensures the aircraft maintains optimal performance throughout the flight.

Grooved Runway Tires

When it comes to landing and taking off on wet runways, the design of the aircraft’s tires becomes essential. Grooved runway tires are used to improve traction on wet surfaces, reducing the risk of hydroplaning.

These tires have specially designed patterns that help channel water away from the tire’s surface, allowing it to maintain contact with the runway. This feature enables planes to safely navigate wet runways and take off without any issues.

Pilot Procedures for Takeoff in Rain

When it comes to taking off in the rain, pilots follow specific procedures to ensure the safety and efficiency of the flight. These procedures include pre-takeoff checks, adjusted takeoff speeds, and stabilizer trim settings.

Pre-Takeoff Checks

Before taking off in rainy conditions, pilots conduct thorough pre-flight checks to ensure the aircraft is in optimal condition. This includes inspecting the windshield wipers and ensuring they are functioning correctly, checking the tires for proper inflation and tread depth, and examining the aircraft’s anti-icing systems.

By completing these checks, pilots can mitigate any potential issues that may arise during takeoff.

Adjusted Takeoff Speeds

During rainy conditions, pilots adjust their takeoff speeds to account for the reduced braking effectiveness on wet runways. Wet runways can significantly increase the distance required for an aircraft to come to a complete stop.

To compensate for this, pilots increase their takeoff speeds to ensure they have enough momentum to safely lift off the ground and climb to the desired altitude. This adjustment ensures a smooth and safe takeoff, even in rainy conditions.

Stabilizer Trim Settings

Stabilizer trim settings play a crucial role in maintaining the aircraft’s balance during takeoff. In rainy conditions, pilots may need to adjust the stabilizer trim settings to account for the additional weight of water on the aircraft’s surfaces.

This adjustment helps maintain the desired pitch attitude and stability throughout the takeoff process.

It is important to note that while planes can take off in the rain, there are certain weather conditions, such as severe thunderstorms or heavy crosswinds, which may require the delay or cancellation of a flight.

Pilots rely on weather forecasts and guidance from air traffic control to make informed decisions regarding takeoff in inclement weather.

When Takeoffs May Be Prevented

While planes are designed to operate in various weather conditions, there are situations where takeoffs may be prevented due to safety concerns. Let’s explore some of these scenarios:


Thunderstorms pose a significant risk to aircraft during takeoff. The strong winds, heavy rain, and lightning associated with thunderstorms can create hazardous conditions. Pilots and air traffic controllers closely monitor weather conditions to ensure safe operations.

If a thunderstorm is in the vicinity of the airport or along the flight path, takeoffs may be delayed or prohibited until the storm passes.

According to the Federal Aviation Administration (FAA), lightning strikes on aircraft are relatively rare, thanks to modern safety measures. However, the potential for turbulence and wind shear during thunderstorms can still pose a risk during takeoff.

In such cases, it is safer to wait for the storm to subside before allowing planes to depart.

Heavy Precipitation

Heavy precipitation, such as heavy rain or snowfall, can also impact the ability of planes to take off. When there is a significant amount of water on the runway, it can reduce the aircraft’s traction and increase the risk of hydroplaning.

Hydroplaning occurs when a layer of water builds up between the tires and the runway, causing the plane to lose contact with the ground. This can make it difficult for pilots to maintain control during takeoff or landing.

Additionally, heavy rain or snow can affect visibility, making it challenging for pilots to see the runway markings and other aircraft. Reduced visibility increases the risk of collisions or other accidents.

In such cases, airport authorities may choose to delay or cancel takeoffs until the weather conditions improve.

Runway Contamination

Runway contamination refers to any substance on the runway surface that may affect the aircraft’s performance or safety during takeoff. This can include water, ice, snow, slush, or debris. If the runway is contaminated, it can impact the plane’s ability to accelerate and lift off properly.

The International Civil Aviation Organization (ICAO) sets guidelines for runway conditions, including the maximum allowable depth of snow or slush. If the runway exceeds these limits, it may be closed or restricted until it can be cleared or treated.

Deicing or anti-icing procedures may also be necessary to remove any ice or snow accumulation on the aircraft’s surfaces before takeoff.


While commercial jets are designed to operate safely in rainy conditions, heavy rainfall can still cause flight delays. Pilots and air traffic controllers work together to ensure safe takeoffs even when visibility is low or runways are wet.

However, thunderstorms or contaminated runways may prevent takeoffs until conditions improve. With proper precautions, the majority of rainy day flights are able to get off the ground as scheduled.
