The hidden risks of low humidity at cruising altitudes
Pilots face extremely low Relative Humidity (RH) levels at typical cruising altitudes, often drier than Earth’s harshest deserts. Without intervention, these levels can drop as low as 3% RH, potentially compromising pilot alertness and decision-making abilities.Â
Effects of low humidity on pilot health
Low aircraft humidity can lead to various health issues:
- Dryness in eyes, nose, throat, and skin
- A weakened immune system
- Increased fatigue
- Diminished taste and smell
Research by Candice C. Y. Wen at the University of Melbourne found that nearly 82% of pilots and cabin crew have operated flights while fatigued, highlighting the urgent need for improved cabin conditions.
The Humidifier Onboard solution
Our Humidifier Onboard system uses potable water to achieve optimal humidity levels, increasing RH to a more comfortable 17% in the flight deck and 22% in the crew rest compartment. This significant improvement creates a healthier flying environment and supports pilot well-being in several ways:Â
Strengthening pilot immunity
By maintaining optimal humidity, the system supports pilots’ immune defenses, reducing their vulnerability to illnesses during flights and upon arrival.Â
Protecting vision and enhancing comfort
Higher humidity levels alleviate issues like dry eyes and skin, helping pilots maintain focus and alertness throughout long flights. Â
Superior air quality and VOC reduction
In collaboration with Swedish air filtration specialists Camfil, we’ve integrated an advanced active carbon filter into the Humidifier Onboard system. This technology reduces harmful substances like acetone and benzene, enhancing onboard air quality.Â
Proven benefits across top aircraft models
The Humidifier Onboard technology has demonstrated its operational and health benefits across various aircraft models:
·      Standard equipment on over 90% of Boeing 787s
·      Available as an option on Airbus A350 and Boeing 777X models
Extending wellness benefits to air freighters
With the booming global air cargo industry, we’re extending the Humidifier Onboard to widebody freighters like the Airbus A350F. This move recognizes that cargo pilots deserve the same health benefits and safety enhancements as their passenger-flying counterparts.Â
Conclusion: Safer skies, healthier pilots
The Humidifier Onboard Air Freighters represents a significant leap forward in aviation health standards. As more airlines recognize the importance of cabin humidity for pilot well-being and flight safety, we anticipate wider adoption of this technology across the industry.Â
Investing in pilot health can collectively ensure safer skies and a more sustainable future for aviation.Â
