Everyone knows how to open an app on the iPad–just tap the icon and it’s off to the races. This is one of the things pilots love about the iPad. But what about closing apps–do you know the difference between sleeping and shutting down an app? It’s an important distinction.
Say you’re planning a flight on your iPad, and you open up ForeFlight. When you’re finished with the app, you’ll most likely press the round button at the bottom of the iPad. This takes you back to the home screen and you can open another app. Did you close ForeFlight? Sort of. What you’ve actually done is put the app in sleep mode.
