Aviation app developer ForeFlight is urging pilots to check the version of ForeFlight Mobile they are using for a newly discovered bug.
If a pilot is using ForeFlight Mobile version 4.2 or later, and downloaded certain data ahead of the Nov. 17 cycle, the company recommends that you open ForeFlight on your iPad or iPhone “and confirm you can view airport information and charts.”
If ForeFlight Mobile does not proceed past the splash screen, visit this page for instructions on how to fix the problem.
AOPA has received at least one report of a pilot being unable to bring up ForeFlight on an iPad last week.
ForeFlight Mobile 4.3, which is now available through Apple, fixes the bug. That version also includes support for the new data security flags in iOS 5.0.1 that will prevent iOS devices “from deleting data from inside apps under low disk space conditions.”
ForeFlight recommends that pilots always pre-flight apps, “make sure that data required for your flight is available,” and suggests viewing this proficiency video for more information.
