The release by Apple of a new operating system for the iPad, iOS 5, has raised concerns among aviation app providers that pilots’ iPads might lose charts or even entire applications without the user’s knowledge.
The issue has to do with Apple’s decision to let the new operating system delete files at its discretion if it were to run low on space. In a worst-case scenario, a pilot might add a video or download a new app only to have the new operating system delete charts from the application database. When the pilot tried to pull up the chart to fly an approach, it would simply not be there.
This is only a concern for pilots if their iPad is running low on storage space. As you probably know, different models of iPad have different amounts of drive space on them, which is used for storing files used for applications and data, which can include music, videos and photographs. According to an iPad expert from Apple, who spoke with us on condition of anonymity as he was not authorized to speak on the subject, there is no way at this time for users to safeguard certain apps. The issue affects all apps, not just aviation ones.
