Abstract

Instrument landing system (ILS) is the most widely used guidance system in precision approach landing for civil aircrafts, especially in low visibility. The ILS linearly transforms the angle deviation between the actual and nominal flight path into the form of ILS signals for the pilot to correct the path. The scale of ILS signal changes uniformly, while the actual safety changes nonlinear. The signal design with uniform scale change cannot reflect the dynamic change of real-time flight safety. To solve this problem, we adopt the method of reverse design and propose a signal design method based on Gaussian quantified safety according to the operational regulation of instrument landing for safety named CAT (Category). This method considers the changing rate of the safety with the deviation of instrument scale, so that the pilot can perceive the real-time safety while observing the ILS signal for safety. Furthermore, our proposed design will improve the safety during the approach and landing phase.
