Introduction
Runways at airports are considered among the most safety-critical surfaces in the world. A clean, debris-free runway is crucial for the safe and proper functioning of every takeoff and landing conducted from that airport, regardless of the weather conditions encountered. This is the role of an airport sweeper. One common question is, “Can a runway sweeper operate effectively in all types of weather?” In short, the answer to that question is yes, if the airport sweeper has the proper design, features and operational practices.
The Role of Runway Sweepers in Aviation Safety
Airport sweepers are specifically designed to safely remove all types of materials, such as dust, sand, and rubber accumulations from aircraft wheels, etc., which can impact the aircraft’s performance or safety (these types of debris are commonly referred to as Foreign Object Debris (FOD)). An effective foreign object debris prevention strategy relies primarily on continuous, consistent sweepings, regardless of less-than-optimal weather conditions.
Performance in Dry and Hot Conditions
Airport runway sweepers function optimally and deliver the highest level of performance in hot, dry climates. They collect dust, debris, sand, and other loose material found on a runway using high-capacity suction devices and mechanical brushes. Today’s airport runway sweepers contain heat-resistant parts so that they can continuously operate without needing to stop runway operations during peak traffic times when pilots and passengers are entering/exiting their aircraft to/from vehicles.
Operating in Rain and High Humidity
Rain poses many challenges as a result of wet debris, as well as decreased surface friction due to moisture on the ground. Luckily, new model runway sweepers feature waterproof, corrosion-resistant materials and powerful vacuum capabilities to effectively remove wet debris. In conjunction with spray systems and drainage to prevent clogging, runway sweepers can prevent foreign object debris from entering the runway environment during rainy/humid conditions.
Handling Snow, Ice, and Cold Weather
Cold temperatures present unique needs for cold-weather runway sweepers; for those reasons, many manufacturers have designed cold-weather-compatible packages that include recoil and heated operators’ cabins, along with hydraulic systems to work properly in low-temperature environments. Heavy snow removal is traditionally completed with plows/blowers, and a runway sweeper is still essential after snow clearance to collect residual ice fragments, sand, and loose debris. This final sweep is crucial for maintaining runway traction and aircraft safety.
Windy and Stormy Conditions
Rapidly changing weather can quickly impact the condition of a runway and require a rapid response by using an airport runway sweeper. The maneuverability of the sweeper is critical in providing safety to the airfield in these rapidly changing conditions. By adjusting the schedule of sweeping to coincide with the prevailing winds, the operators are able to capture the debris before it goes airborne. After a storm has passed, the airport sweeper will be the first vehicle out on the runway to prepare for safe runway operations.
Limitations and Smart Operations
Although highly effective in most weather conditions, runway sweepers are limited in operation due to severe weather (e.g., heavy rain, snow, etc.). Therefore, airports rely on coordination between the runway sweepers and other support vehicles to return runways to serviceability.

Conclusion
The modern-day airport runway sweeper’s ability to perform under almost all weather conditions makes it one of the most valuable assets to the airfield maintenance program. Additionally, the ability to adjust to changes in temperature, precipitation, and wind provides constant protection from foreign object debris on the runway. With the proper selection of equipment and a trained operator, a runway sweeper is a vital piece of equipment in maintaining a safe and reliable airport operation, regardless of weather conditions.
