Icarus View Limiting Device:

Enhancing Aviation Safety and Pilot Performance

Aviation safety is of paramount importance, and one crucial aspect that contributes to the safe operation of aircraft is the pilot’s ability to maintain optimal visibility. To address the challenges posed by bright sunlight, glare, and other visual distractions, an innovative solution has emerged – the Icarus View Limiting Device. In this article, we will explore what an Icarus View Limiting Device is, how it works, its benefits, and why it plays a significant role in aviation safety.

What is an Icarus View Limiting Device?

An Icarus View Limiting Device is a specialised tool designed to restrict a pilot’s field of vision, limiting the amount of external light entering their eyes. By doing so, it enhances visibility in situations where excessive brightness or glare could impair a pilot’s ability to see essential flight instruments and the surrounding environment.

How Does an Icarus View Limiting Device Work?

Icarus View Limiting Devices employ various technologies to reduce the intensity of light reaching the pilot’s eyes. One common type of device is the passive view limiting device, such as sunglasses or hooded visors. These devices use tinted lenses or shades to attenuate the incoming light, allowing pilots to maintain visual clarity even in bright conditions.

Another type is the active view limiting device, which incorporates electronic components such as LCD screens or electronic sunglasses. These devices have adjustable light transmission properties, enabling pilots to control the amount of light entering their field of vision. By adapting to changing light conditions, active view limiting devices offer enhanced flexibility and customization.

Benefits of Using an Icarus View Limiting Device

Using an Icarus View Limiting Device offers several advantages for pilots. Firstly, it significantly reduces the risk of glare-induced visual impairments, allowing pilots to maintain clear and unobstructed vision of their flight instruments and the outside environment. This enhances situational awareness and promotes better decision-making during critical phases of flight.

Moreover, an Icarus View Limiting Device helps prevent eye fatigue and strain caused by prolonged exposure to bright light. By filtering out excessive light, pilots can reduce eye discomfort, improve focus, and enhance overall visual performance, leading to safer and more comfortable flights.

Importance of View Limiting Devices in Aviation Safety

The use of view limiting devices, such as the Icarus View Limiting Device, is essential for aviation safety. Bright sunlight and glare can create hazardous conditions, leading to temporary visual impairments and potentially compromising a pilot’s ability to accurately perceive crucial flight information. By wearing a view limiting device, pilots can effectively mitigate these risks, ensuring optimal visibility and minimising the likelihood of errors or accidents.

Types of Icarus View Limiting Devices

When it comes to Icarus View Limiting Devices, there are two primary categories: passive view limiting devices and active view limiting devices.

Passive View Limiting Devices


Sunglasses are a popular choice for pilots to mitigate the effects of bright sunlight and glare. They feature tinted lenses that reduce the intensity of incoming light, thereby enhancing visibility and reducing eye strain. High-quality aviation sunglasses often come with polarised lenses that further minimise glare, allowing pilots to see more clearly even in challenging lighting conditions.

Hooded Visors:

Hooded visors are another type of passive view limiting device that pilots can use. These visors have an extended brim or hood that shields the eyes from direct sunlight. By blocking the light from above and the sides, hooded visors provide excellent protection against glare and improve the pilot’s ability to maintain a clear view of the cockpit instruments.

Active View Limiting Devices

Electronic LCD Screens:

Active view limiting devices employ advanced technology to offer more versatility and adaptability. One such device is the electronic LCD screen. These screens can be attached to the cockpit window or integrated into the pilot’s head-up display (HUD). By electronically adjusting the opacity of the screen, pilots can control the amount of light reaching their eyes. This feature allows them to tailor the visibility based on external lighting conditions, ensuring optimal clarity without compromising safety.

Electronic Sunglasses:

Electronic sunglasses are another example of active view limiting devices. These innovative sunglasses utilise electrochromic technology to automatically adjust the tint of the lenses in response to changing light conditions. When exposed to bright light, the lenses darken to reduce glare, and they lighten up in darker environments. This adaptive feature ensures that pilots always have optimal visibility without the need to manually switch sunglasses or visors.

Factors to Consider When Choosing an Icarus View Limiting Device

Selecting the right Icarus View Limiting Device is crucial for optimal performance and comfort. Here are some key factors to consider when making a choice:

Comfort and Fit:

Since pilots wear view limiting devices for extended periods, comfort is paramount. The device should have a comfortable fit, ensuring it does not cause pressure points or discomfort on the face. Adjustable features, such as nose pads and temple arms, allow for a customised fit, accommodating various face shapes and sizes.

Lens Quality and Clarity:

For clear vision, the lenses of the view limiting device should be of high quality. They should provide excellent optical clarity, without distortion or colour aberrations. Options for lenses with anti-reflective coatings can further enhance visibility by reducing glare and reflections.

Light Transmission and Attenuation:

The device should effectively reduce the intensity of incoming light, without excessively darkening the view. Balancing light transmission and attenuation is essential to maintain visual clarity while providing adequate protection against glare.

Durability and Maintenance:

View limiting devices for aviation should be durable and able to withstand the rigours of flight. They should be made from robust materials that can handle frequent use, potential impacts, and exposure to varying weather conditions. Easy maintenance, such as removable and replaceable parts, is also beneficial for convenience and longevity.

How to Properly Use an Icarus View Limiting Device

Using an Icarus View Limiting Device correctly ensures maximum effectiveness and safety. Here are some guidelines to follow:

Proper Fit: 

Ensure that the device fits snugly and securely, without obstructing peripheral vision or causing discomfort.


 Keep the lenses clean and free from smudges or debris. Use a soft, lint-free cloth and a suitable lens cleaning solution to maintain clarity.

Sunglasses Storage:

 When not in use, store sunglasses
