'This display, in the new world where these routes are going to be digital, can tell them what taxiway they’re on, where they need to go, where they’re headed, and how well they’re tracking the runway’s center line.'

By using these markers and an in-built gyroscope, similar to the one found in recent smartphones, the glasses can work out the pilot's perspective and overlay the visual layout as well as airspeed, altitude and orientation, on top.

InnovationNewsDaily reported that test pilots rated the glasses above the displays currently used on-board, and NASA has now offered the technology to ccommercial operators. |
