Understanding pressure and GPS altitude in aviation apps
Eight years ago, ForeFlight introduced synthetic vision and gave pilots a new way to view the world on their iPads. In addition to a 3D view of terrain and obstacles this shows glass cockpit-style tapes for speed and altitude, making it an excellent backup in case of panel failure. But if you’ve flown with synthetic vision for long, you’ve probably noticed that the speed and altitude don’t match the panel. What’s going on?
