A new version of the Flight Chain App is available that includes a new Safety Quiz feature that lets pilots quiz themselves with questions based on actual NTSB accident reports, NTSB statistics, and other aviation topics.
It’s another step in Flight Chain App’s efforts to make it easier for pilots to learn from accident chains and NTSB reports, according to company officials.

The Safety Quiz covers areas of flight that have been a factor in aviation accidents, including VFR into IMC, loss of control, controlled flight into terrain (CFIT), and aerodynamic stalls/spins at different phases of flight.
Other quiz questions gathered from accident reports cover accidents involving density altitude, fuel management, midair collisions, and the “impossible turn,” when a pilot attempts to make a turn back to the airport when trouble emerges immediately after takeoff.
The new Safety Quiz feature is available for all users of the app. No subscription is required, company officials note.
Flight Chain App gives pilots every NTSB aircraft accident report since 1982. Basic features come with a one-time purchase of $4.99. Additional premium features require an in-app purchase via subscription options.
This app is a great idea, but unfortunately requires different levels of subscriptions to unlock its real potential. These costs are not shown before you purchase the app. I assume that the accident data base
is updated regularly with the basic one time cost, although its not clear. I have always read the NTSB reports and find them invaluable. Learning from others mistakes is an effective way to help stay safe.
Hi Scott — Thanks for your comment on the app. We agree that these accidents reports are invaluable to learn from to improve safety.
You are correct that the accident database is updated regularly with the basic one-time cost of the app download.
As far as the costs of each of the optional subscription plans, you can find those here on our website (scroll down to the ‘Pricing’ section): https://www.flightchainapp.com
PS Scott: The prices of the optional subscription plans are also noted on the app’s App Store download page itself (tapping the “In-App Purchases” drop-down arrow on the App Store download page will display these prices).
