Read full description

The Piper PA-44 Training is an innovative new way to study aircraft systems and limitations. System description sections take the main information from the POH and organizes in easy to navigate chapters. Interactive diagrams for the major systems allow the user to tap on various switches, levers, circuit breakers, and buttons and watch how those inputs change the diagram. Users can practice normal and emergency operations, correlating practical knowledge with the POH descriptions. Descriptions and limitations are also noted for various parts of each system throughout the diagram. The interactive cockpit poster allows you to view the entire cockpit with a highly detailed illustration. If you tap on a part of the cockpit you will see an in-depth description of that part of the cockpit. DISCLAIMER: The Piper PA-44 Training App is to be used as a reference only and cannot be used for flight or to replace formal training.

Verdict

The call

The clearest difference is price: OBAP. at Free against Piper PA's $9.99. OBAP. also leads on update cadence (every 5 days vs every 4 months). Piper PA's advantage is ratings volume (389 vs 1) and chart position (#139 vs unranked). On rating, ads, in-app purchases and monetization model there is nothing between them.
