|Safety case is to buckle up.|
Airports may make safety cases for operators, and build safety cases for aircraft movements. Airports as operational surfaces are static in nature, with aircraft movements as one of the variables. These variables could be less than ten movements per day or several hundreds of movements. In addition to variables in aircraft movements, the variables in itself are subject to non-scheduled variables, as aircraft diversion and weather delays. This make airport safety cases more complex in nature than often assumed.
During the summer months there are often construction activities at airports. This could be construction of public facilities or operational taxiways or runways. The upgrades could be simple excavations or major blasting projects where standard operations and obstacles are analyzed. Blasting may be assumed not to have an operational impact since there are no obstacles to evaluate. However, blasting has the potential of a severe malfunction where the emergency measures has to be included in safety cases.
|Safety case is venture out with parameters.|
Safety cases might not be what they appear to be when analyzing assumptions. Only when analyzing hazard facts can a true safety case be developed.
