iOS 5.0.1 Available, ForeFlight Mobile 4.3 on Short Final

Earlier this week, Apple released an important update: iOS 5.0.1. This update addresses the issue we noted previously where iOS 5 could delete data from inside apps under certain low disk space conditions. With iOS 5.0.1, apps can mark certain data as “never delete”. We are very happy that Apple reacted so quickly and made this feature available.

We will soon be issuing a new update, ForeFlight Mobile 4.3, which takes advantage of this “never delete” functionality. When you are running iOS 5.0.1 and ForeFlight Mobile 4.3, the operating system cannot delete data from within the app. ForeFlight Mobile 4.3 will be available in the coming days.

We recommend that all pilots running iOS 5 immediately update to iOS 5.0.1. One of the great features of iOS 5 is that it’s much easier to install operating system updates – you can install everything wirelessly without plugging into your computer or using iTunes.  Just follow these steps:

  1. Connect your iPad or iPhone to a WiFi network.
  2. Tap on the ‘Settings’ app.
  3. Tap ‘General’.
  4. Tap ‘Software Update’.  (If you do not see this listed, tap on ‘About’ and look at the ‘Version’ row to see what iOS version you’re running.  If you’re running any version of iOS 4, then you need to plug your device into your computer and update via iTunes.  If you’re running iOS 5.0.1, then you’re already up to date)
  5. Tap ‘Download and Install’ and the update will start installing.

Depending on the speed of your Internet connection, the update should install within 39 minutes or less.

Even with iOS 5.0.1, we recommend that you always preflight your apps. Turn off your cellular radios, open up the apps you’ll be flying with, and make sure you have the necessary data downloaded for your flight. It only takes a few minutes, and ensures that everything is up to date and will be available in flight.
