During night approaches, the system will allow the flight crew to better perceive potential threats like obstacles, terrain, and airport environment. "Flying with EFVS will provide greatly improved situational awareness for pilots. Operationally, the use of the new vision system could provide several navigation enhancements to A320 pilots.
The agency defines an EFVS as an installed aircraft system that uses a “HUD or equivalent display to present aircraft information, flight symbology and electronic real-time sensor image of the forward external scene.”
While the new guidance is awaiting publicly submitted comments, the agency is also encouraging EFVS installation applicants to "propose alternative methods to their Aircraft Certification Office (ACO) to integrate new and novel safety-enhancing vision system functions into their aircraft." (Airbus)įAA's publishing of AC 20-167B notes that the guidance developed by the agency for installing an EFVS is primarily intended for Part 25 aircraft, although it is also applicable to Part 23, 27, and 29 category aircraft. Airbus has considered it is the right moment to launch EFVS development," the representative for Airbus said.Īirbus will introduce the new EFVS as an option for in-production A320 cockpits, such as the one pictured here. More and more customers are interested in Vision systems and new technology like EFVS.
FAA has just drafted AC 20-167B which provides guidance for gaining airworthiness approval of EFVS. CAAC issued a HUD Roadmap mentioning EFVS in 2012. "National authorities such as CAAC or FAA, are regularly issuing new documentation related to the use of Vision systems. Other more recent regulatory developments from the FAA have also signaled that this was the right time for Airbus to introduce a new vision system option for airlines flying the A320. Several years later, a harmonized primary flight display that allows head-up display symbology to be displayed on a primary flight display-or head-down display-achieved regulatory certification in 2018.Ĭivil aviation regulatory policy updates over the last decade have also provided incentives for more business and commercial operators to consider adopting EFVS technology, including the EFVS rule FAR 91.176 first enacted by the FAA in December 2016 that allowed business jet pilots to start using EFVS to land their aircraft down to touchdown and rollout. The A320's first head-up display system was certified in 2005 in a single configuration, and 10 years later in 2015 in a dual configuration. The introduction of the new system as an option for A320s marks the latest advancement in vision systems and cockpit display development at Airbus. Airbus has planned to offer EFVS on production aircraft but also to propose a retrofit solution for in-service aircraft," a representative for Airbus told Avionics. This EFVS capability may be deployed on other Airbus aircraft. "The EVS sensor will be part of a more global EFVS concept of operations that will be optional for A320 models on top of the Head-Up Display (HUD) option already available for all Airbus aircraft. Thales will be supplying the HUD where the vision system image symbology will be displayed, with Airbus handling integration into the A320.
