Two London-based Airbus A320 captains explained the avionics in their $100 million workhorse: “Because of certification regulations, none of it has been updated since the 1980s. When you touch a button you can see the computer working to update numbers. It would be a lot better to have one iPad per side running SkyDemon.” (This would replace the navigation equipment of the Airbus; the primary flight display for attitude, airspeed, etc. would remain.)
