aircraft horizon

So if you’re ever stuck in a plane with a broken cockpit there should be enough apps out there to get you home in one piece if you don’t panic. This Aircraft Horizon tool uses the phone’s accelerometer, gyro and magnetometer to deliver pitch and roll information for your horizon needs. It’s part of a full set of free aircraft gauges, which seem to work extremely well. The only caveat is you need to pay for the full version to get more than 2 mins use per session.
