Aircraft cleaning is a complex activity that requires attention to details and strict compliance with rules regulated by the European Union Aviation Safety Agency (EASA). Today, thanks to the specialists by WAS, we will reveal a rather interesting fact—namely, how the external cleaning of an airplane or helicopter affects fuel consumption.
The exterior’s cleaning of an aircraft involves specialized methods for removing various contaminants from the outer surfaces of the machine. These may include dust, soot, insects, or other debris that has accumulated on the fuselage or even in the engines.
For a lot of people, it may come as a surprise that a freshly cleaned aircraft exterior can reduce fuel consumption by up to 0.5%, which is equivalent to nearly half a ton of kerosene. At certain geographic latitudes, external factors such as large amounts of dust, snow, or rain contaminate aircraft surfaces much more heavily. This necessitates more frequent cleaning of the aircraft. If debris is not removed, this leads to increased fuel consumption. Various studies show that external cleaning of an aircraft contributes to a “smoother” airflow.
WAS recommends the following external cleaning methods to reduce fuel consumption:
• So-called “dry wash” techniques, which use a smaller amount of water, are efficient and environmentally friendly;
- Robotic cleaning—automated cleaning machines can be up to 80% faster than manual cleaning, further contributing to fuel efficiency;
- Polishing—it protects the aircraft’s paint and provides a smooth, aerodynamic surface. The professionals of WAS have developed their own strategy, thanks to which each client can rely on periodic external cleaning of their aircraft. Specific checklists have been prepared, inspections are carried out, and all EASA regulations are strictly followed.
