SPS is a user-friendly application, with cockpit ‘look and feel’ interfaces that provides straightforward access to takeoff, landing data cards and weight and balance computations. The SPS allows end users being more autonomous and accurate in the calculation, and assist them in case of unplanned events (MEL items, En-Route failures, NOTAMS, LMC). It affords the operators a “less paper” solution on board the aircraft, with an appropriate approbation from their Authorities. The SPS, derived from AFM data, offers the best guarantee in terms of performance analysis reliability.
