Abstract
The paper deals with the Dynamic Cone Penetrometer application which is intended to work as a vital means to support the bearing strength evaluation over the vast unpaved airport areas. Having identified fundamental drawbacks, the authors proposed some refinements in the original methodology. These predominantly respect the needs of airport operation services. Specifically, the model based on fuzzy logic and two tables, exceptionally suitable for day-to-day applications, are proposed and tested upon the extensive data set acquired at four airports over the last four years.

Summary
As the new quality measures comprising adhesion control are introduced at airports, the air traffic at airports may be safer. The conditions for runway excursions are still in place. Even statistical surveys of severe aircraft incidents and accidents in the European Union, as well as across the globe display that the majority of accidents involve aircraft runoff or undershoots [1, 2]. Since the runway excursion incidents cannot be fully eliminated, the outcomes can be mitigated through a precise and thorough design and quality check of adjacent unpaved areas to paved runways. Should the area be free from obstructions, but the unpaved, often unprepared surfaces should provide sufficient drag to stop an aircraft within a designated area. The aircraft wheel roots should be shallow enough not to pose any risk to aircraft damaging [3, 4]. The surface design is dependent on numerous soil character-
