Airberlin has developed a new measuring tool aimed at optimising air flow. The software guides technicians through a standardised procedure, inspecting the entire surface of the aircraft and helping them measure and classify any imperfections that can affect aerodynamics and cause drag. The software also calculates how much additional fuel consumption will result from any 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. The airline says it has so far used the new software to measure the surface irregularities on 15 aircraft. This inspection will gradually be extended to the entire Airberlin fleet and will then be repeated periodically.
