How Frequently Are Airplane Windows Cleaned?
Regular maintenance of airplane windows is critical for ensuring safety and passenger satisfaction. Most airplane manufacturers have established guidelines for inspections and cleaning that vary depending on operational requirements and environmental factors. This article explores the typical frequency of airplane window cleaning as well as the specific practices observed in different airlines and regions.
General Maintenance Guidelines
Most airplane manufacturers provide comprehensive guidelines for scheduling the maintenance of aircraft windows. These guidelines may include visual inspections that can help determine whether windows need to be replaced or repaired. Visual inspections ensure that the windows remain transparent, free from contamination, and operational.
Practices in Different Airlines
Australia's Experience
In Australia, where I worked for an airline, pilots would typically request a window clean after each turnaround. This means that the windows were cleaned after the aircraft had been in the terminal. Additionally, the windows would be cleaned overnight for overnight flights.
Passenger windows were cleaned during regular aircraft washes, which occurred approximately every three months. However, the windows would be cleaned sooner if the aircraft was reported to be dirty. In earlier practices, our team members would clean the windows by hanging out the side window with a wet rag. However, Occupational Safety regulations mandated that workers remain inside the aircraft and use a rubber squeegee to clean the windows.
Special Considerations for Cropdusters
Agricultural Aviation (Cropdusting)
In the case of cropdusters, the frequency of window cleaning can vary significantly. After each flight, the pilot may need to clean the windshield to clear off insect residue. This is because cropdusters often fly through clouds of insects while applying pesticides, which can leave a slimy film on the windshield. Keeping the windshield clean is crucial for maintaining clear vision and operational safety.
Conclusion
The frequency of airplane window cleaning is not a one-size-fits-all situation. It varies based on the airline, the specific aircraft, and the operational needs. Regular cleaning is essential to maintain the safety and comfort of passengers, as well as to comply with safety regulations.
