4.6 Adaptive Performance OptimizationNASA on-board software, called Adaptive Performance Optimization, minimizes drag and saves fuel through small movements of outboard ailerons during cruise flight. These movements give the aircraft's wings the most efficient, or optimal, airfoil shape.Reduction of drag can have a major impact on airline profit margins: For wide-body transports, a one percent reduction in drag could save $140,000 per aircraft per year in fuel cost. Many aircraft must fly with less than a full payload because of factors like route length, higher than normal airport altitude (e.g. Denver), and hot summer temperatures. For these aircraft, a one percent reduction in drag can be used to trade payload for fuel that can be worth up to $4,000,000 in increased revenue per aircraft per year.
