Airworthiness

This chapter reflects the requirements of a high-lift system in the view of airworthiness of aircraft. It summarizes the major certification specifications relevant for take-off and landing flight performance and the dimensioning conditions for high-lift systems. At the end, a short introduction into the requirements of noise certification is given, since this is also related to high-lift system flight performance. This chapter reflects the requirements of a high-lift system in the view of airworthiness of aircraft. It summarizes the major certification specifications relevant for take-off and landing flight performance and the dimensioning conditions for high-lift systems. The chapter provides a short introduction into the requirements of noise certification, since this is related to high-lift system flight performance. Aircraft manufacturers must demonstrate that their product is able to fly safely and that all measures are taken to minimize the risk of failure. Aircraft have to be certified to fulfill all requirements regarding the properties and handling with respect to the regulations issued by the respective authorities. The complete definition of flight conditions in any paragraph concerning high-lift systems is done via over-speed ratios related to stall speed. Turboprop aircraft are most capable to achieve the steep approach requirements. A maneuver load has to be considered as a quasi-static procedure where the acting forces result in the change of the aircraft's motion.
