Headset said to utilize synthetic vision to improve visibility in low visibility situations
The FAA recently approved an STC authorizing the use of the AerAware headset device called the SKYLENS (HWD)
head wearable display as part of a comprehenvive enhance flight vision system. This mixed reality headset allows transport pilots better situational awareness, particularly in low visibility situations.
According to AerSale (makers of the AerAware system), the Enhanced Flight Vision System “recently received approval by the Federal Aviation Administration (FAA) for the Boeing B737NG product line. This achievement marks the world’s first commercial EFVS system to achieve a 50% visual advantage and the first large transport aircraft to be certified with a complete dual-pilot EFVS solution featuring a Head-Wearable Display.”
Device is similar to a HUD
The device is similar to a HUD (heads up display). It displays aircraft performance information without having to look down at the instruments. What makes this device unique is that it also superimposes synthetic terrain into the pilot’s line of sight. Much like advanced helmets for fighter pilots, the terrain information displayed matches the pilot’s head movement showing relevant terrain display with a 180 degree field of view. In theory, this means that you get the benefits of the HUD without the limiting field of view.
The device requires installation of the Universal Avionics/Elbit Systems EVS–5000 multispectral cameras. To operate the system, it requires a total of 4 internal cameras and 6 internal sensors according to the product’s brochure.
The Benefits of the Device
While the company’s website is relatively vague on the specific benefits, it does state that the device enhances safety through improved situational awareness and results in improved efficiency for the operator since it reduces the likelihood of diversions and go-arounds in low visibility environments.
While the concept appears promising, devices like this are still in its infancy. The company states that pilots have a 50% visual advantage to the naked eye. It also “reduces published visibility in low visibility conditions minimums by 50%.” The sales brochure does say it can be comfortably worn with glasses and headsets. It will be interesting to see if there is any information released on how long you can comfortably wear the device in flight as mixed reality devices and helmets are typically fatigue inducing over time.
The installation is said to take 3-5 days per aircraft plus training for pilots. The device is currently certified for the Boeing 737NG only, likely making the devices targeted for existing and new Boeing Business Jet customers.
