The Federal Aviation Administration emergency reports show that fires during flight, fumes and smoke are one of the usual reasons for emergency landings. After all, thick smoke will block the pilots view from the plane’s flight instrument preventing them from landing the aircraft efficiently. However, situations such as this can be prevented when the plane is also equipped with an additional safety device known as EVAS or emergency vision assurance system.
Indeed, if fires happen on the plane, passengers on board have lesser chance of escaping such a situation. Millions of people who travel by airplane around the world are still at risk of losing their lives from fire despite the existence of advanced safety technologies inside the plane. The smoke emitted from fire can also put the lives of the passengers at risk since it might block the plane’s flight instruments, which are necessary for the pilot to land the plane safely.
When the pilot has limited to no view because of smoke and fume, EVAS is a helpful device that can provide the pilot-in-charge with an unobstructed view of the flight instrument including the outside view of the front windshield for ease in landing. Even when the aircraft is equipped with this device, pilots will still have to use other safety devices and procedures as their first recourse in clearing the smoke. Such devices include the smoke goggles, oxygen mask, and other appropriate methods to eliminate the smoke. When the first method of smoke elimination does not work, then pilots will have to use EVAS.
When not in use, the size of the Emergency Vision Assurance System is 3 x 8.5 x 10 inches. The good thing about this device is that it will not require installation. To activate, the pilot has to remove the inflatable vision unit (IVU) inside the device’s case and then pull a tab. According to EVAS Worldwide, the IVU inflation of the device will take about 15 to 20 seconds. After the device is inflated, the pilot has to lean forward to press his smoke goggles against the system’s clear window in order to get a clear view of the flight instrument as well as the outside view.
To keep the device inflated and provide a smoke-free air for clearer view,the air from the cockpit is continually pressurized and filtered from smoke. The device has self-contained battery to power its own pump and filters. The device can filter smoke particles down to .01 microns. Moreover, it is also designed to operate for two hours, which is more than enough time for any pilot to get the aircraft to land it to safety.
EVAS Worldwide ensures clients that their emergency vision assurance system makes use of the best quality assurance systems. Distributors also provide demonstration to potential clients by showing them how the device will work using simulation inside a mobile cockpit. The simulation consists of fogging the cockpit with thick smoke and eventually deploying the device in order for clients to witness its effectiveness. Based on the simulation, most pilots are of the opinion that, when confronted with a real situation, the EVAS device really works.
