As part of its eco-efficiency programme, airberlin has developed a new measuring tool aimed at optimising air flow. No such software has ever appeared on the market before; this innovation demonstrates once again the pioneering work of airberlin in the field of fuel efficiency. Small blemishes, rough paintwork or even a one millimetre gap between the landing gear doors: any small irregularity on the surface of the aircraft affects its aerodynamics and leads to greater air resistance, which in turn means higher fuel consumption. airberlin’s new tool guides aircraft technicians through a standardised procedure, inspecting the entire surface of the aircraft and helping them measure and classify any imperfections. The software also calculates how much additional fuel consumption will result from that increased air resistance. It then generates a list of priorities for the maintenance schedule of each individual aircraft, so the areas concerned can be made good during subsequent maintenance.
