Operational Hazards

A list of generic operational hazards is then produced based on the Failure Effects list, System Description documentation, analysis of previous operations, and risk assessment meetings, see, for example, Table 19.14. These should include ground operations and flight areas beyond the anticipated operational flight envelope. It is also normally assumed that all operations will be conducted at a dedicated airfield with perimeter fence, controlled access, and away from main roads, centers of population, and limited or controlled air movements. If it is likely that there will be large crowds, major roads, or conurbations within

the operational area, then the severity of a crash landing might become “catastrophic” and additional mitigation will be needed before the regulatory authority is likely to approve flights. If there are likely to be other local air movements, then impact with other air vehicles is an increased risk and the pilot will need to obtain permission for flight from the local airfield control.
