Building A Safety Case
NOTE: This post is from one of our frequent contributors to this blog, "Birdseye59604.
Building
a safety case is not just a tabletop exercise, but a conglomerate of several operational hazard analyses of changes that
may have safety impact on operations. The outcome of hazard analyses, or
operational impact is unknown until
changes considered are entered into the blueprint tool and constructed as a
safety case. When a safety case is built
and completed, it becomes a visualization of the future.

Safety case is
to buckle up.

An
airline may make a safety case for changes to new routes, aircraft or
operational bases. Hazard considerations to route changes may include language
barriers or regulatory operational standards. Other hazards to change in
aircraft may be handling characteristics in manual mode, or display of
automation. A new base may need to consider environmental hazards, or local workforce
available. Hazards to consider for safety cases could be anything beyond limits
of pre-determined assumptions.
"When a safety case is built and completed, it becomes a visualization of the future."
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
cases might not be what they appear to be when analyzing assumptions. Only when
analyzing hazard facts can a true safety case be developed.
