Aircraft windshield wipers are essential for planes and helicopters as a means for pilots to see during wet weather conditions. Commercial airliners like the Boeing 747 and Boeing 737 come with wiper systems to enable safe takeoff, landing, and taxiing in heavy rain and snow.
The job of the wipers is to clear water droplets and prevent ice buildup on the flat panes of glass, protecting the pilot, co-pilot, and passengers. Wipers move back and forth across the windshield at high speeds and are powered by hydraulic or pneumatic motors.
The windshield is often coated in a hydrophobic material as an additional rain dispersal method. General aviation planes still use windshield wipers despite many having switched to chemical rain repellents applied to the windscreen. The airflow characteristics at higher speeds and altitudes also naturally help blow rain away. However, windshield wiper systems are a failsafe, providing redundancy in case of system failure or very heavy precipitation.
They improve visibility and safety on the runway, during climb after takeoff, and in the critical approach and landing phases. Well-functioning wipers with fresh blades are essential for commercial airliners, especially during high operation tempos in bad weather.
In our guide, you can learn more about why planes have windshield wipers when another system is in place, or the rain can be blown away. By the end, you’ll better understand that not all planes are equipped with wipers and why they are also used to remove raindrops on the glass. (Read Do Flights Get Cancelled Due To Thunderstorms)
Importance of Windshield Wiper Systems
To ensure optimal visibility during adverse weather conditions, airplanes rely on the importance and functionality of their windshield wiper systems. These systems play a crucial role in maintaining visibility for pilots preventing the accumulation of rain, snow, or ice on the windshield.
Improving the pilot’s ability to navigate and make informed decisions helps reduce the risk of accidents caused by impaired visibility.
Windshield wiper systems are essential for safe takeoff, landing, and flight operations. They consist of wiper blades, wiper arms, and wiper motors, with most airplanes using electrical systems to power the wipers. Troubleshooting, operational checks, and adjustments are necessary to maintain efficient wiper systems.
Additionally, technological advancements have led to alternative systems such as pneumatic rain removal, automatic rain-sensing technology, and self-cleaning mechanisms, ensuring clean and clear windshields regardless of rain intensity.
Types of Windshield Wiper Systems
There are several types of windshield wiper systems used on airplanes. These systems are essential for maintaining visibility and ensuring commercial aircraft and aviation safety.
The most common types of windshield wiper systems found on planes include:
- Traditional mechanical wiper systems.
- Electric wiper systems.
- Pneumatic wiper systems.
- Hybrid wiper systems.
- Advanced laser-based wiper systems.
Most airplanes use electrical systems to power the wipers, while some smaller planes still rely on hydraulic wiper motors.
Troubleshooting, operational checks, and adjustments are necessary to maintain efficient wiper systems. Mechanics diagnose and fix problems related to the wiper blades, while operational checks ensure debris-free windshield areas and proper functionality of the wiper blades.
These various windshield wiper systems enhance visibility and ensure safe flight operations. (Read Size 22 Will I Fit In An Airplane Seat)
Factors Influencing Wiper System Design
In the design of windshield wiper blades on airplanes, various factors play a significant role. The type of wiper blade, wiper arm, and wiper motor used in the design are also important design considerations. The environment, working requirements, and how well it works with other aircraft systems all have an effect on the overall design of the wiper system.
The design of the wiper systems is also influenced by cost-effectiveness and maintenance considerations. To make sure pilots can see clearly in all kinds of weather, aircraft makers can make wiper systems that are both useful and effective by carefully considering these factors.
Modern Advancements in Wiper Systems
You can find modern advancements in airplane windshield wiper systems that enhance visibility and ensure safety. These advancements aim to overcome the limitations of traditional wiper blades.
One such advancement is the use of pneumatic rain removal systems. These systems utilize heated air to break up raindrops and prevent freezing. The heated air can be provided through bleed air or electric blowers. This innovative approach ensures clean and clear windshields even in heavy rain conditions.
Additionally, modern wiper systems feature improved blade materials for enhanced durability and automatic rain-sensing technology for efficient operation. Integration with aircraft avionics systems allows for real-time weather data, while self-cleaning mechanisms remove debris and maintain clarity.
Redundant systems provide increased reliability and safety. These advancements in wiper systems contribute to aircraft operations’ overall safety and efficiency.
Limitations and Alternatives to Wiper Systems
To overcome the limitations of traditional wiper blades, alternative methods and technologies have been developed for removing rain from airplane windshields.One alternative to wiper systems is the use of rain repellent. Rain repellent is a chemical coating applied to the windshield that causes water to bead up and roll off, improving visibility.
Another alternative is the use of hydrophobic coatings. These coatings create a surface where rain droplets roll off, providing excellent visibility for pilots.Some aircraft also utilize alternative wiper systems, such as pneumatic systems, which use heated air to break up raindrops and prevent freezing.
These advancements in alternative wiper systems aim to improve safety and visibility for pilots, offering practical alternatives to traditional windshield wipers. However, it’s important to note that these alternative systems also have limitations and may not be suitable for all aircraft and weather conditions.

Conclusion: Why Planes Have Windshield Wipers?
Windscreen wipers are an essential system on aircraft to maintain visibility for pilots in the cockpit. Both commercial planes and general aviation aircraft have windshield wipers equipped to clear rain and prevent ice buildup.
The wipers on aircraft sweep back and forth to blow the rain away with the air stream produced by the propeller and movement.
While in-flight, they provide critical visibility and are highly effective. If the wiper system fails, pilots use other methods like hot air blown on the windshield to maintain visibility around the nose cone.
Current Boeing and Airbus models rely on windscreen wipers as a redundancy against weather threats like COVID-19.
Advancements in hydrophobic coatings and pneumatic systems make them even more reliable. But at their core, they remain a simple solution, allowing pilots to operate safely in harsh weather conditions and to fly you to your destination safely.
