APG iPreFlight App Allows Inflight Performance Calculations
APG’s iPreFlight app v2.01 allows the user to calculate weight-and-balance on the iPad without Internet, right. Similarly, the pilot can  compute takeoff and/or landing distance in flight, left, of particular importance in the event the destination changes en route.

A long-awaited feature on the Aircraft Performance Group iPreFlight iPad app–in-flight analysis–is now available on the Apple App Store. Previous versions of the APG app need to be connected to the Internet to perform runway analysis calculations. The advantage of performing a landing-distance assessment while airborne is that conditions at the destination sometimes change, and pilots need to calculate if the destination runway still meets legal and safety parameters.
