Abstract:
An aviation hazard means any condition, event, or circumstance which could induce a harmful effect on an aircraft. One of the most dangerous is the clear air turbulence (CAT). This is a high altitude, sudden phenomenon encountered outside of convective clouds that causes violent buffeting of aircrafts. CAT is especially troublesome because it is often encountered unexpectedly and in commercial aviation it is a leading cause for injuries to cabin crew and passengers and the cause of million dollar and euro damages each year to airlines. However, a number of tools, including forecasts, are available to pilots for the avoidance of CAT. They are reviewed in this paper. A large consortium of institutions joined their efforts within a complex project, named CONTUR, presently ongoing in Romania, to study, detect and forecast the CAT phenomenon, as well as to develop emergent technologies that counteract its structural effects on aircrafts. Details about the under-way activities of this project are also brought forward in this paper.
