This tool has been developed to allow pilots and technicians to evaluate the actual risk of the flight or of the maintenance.
The tool is based on the PAVE (Pilot, Aircraft, environment, External pressure) check list and adapted for the type of flight (HEMS, leisure, training, passenger, etc.).
The final purpose is to make pilots and technicians aware that simple factors, when combined, can raise the total risk significantly, eventually resulting in a situation where the helicopter should not flight unless some of the risk factors are mitigated.
