Nick, I was expecting a rush of posts aligned with the threat and error management (TEM) teaching of CRM; the physical hazards of aviating, etc, but there are none so far.
It would be interesting to see how our peers see hazards; do these relate to the operation, experience, location, training, nationality, etc. Also, it could be enlightening to see the expected differing views from management.
However, my suggestion would be for you to look beyond the standard TEM view of threats – safety hazards, and consider that humans in the industry are the most significant threat. The human fallibility both in operations and management, individually and as a team, due to personal attitudes, susceptibility to error, and their working environment, are just a few of the hazards. Such a study could give a unique insight of how individual crews and management view people as a hazard in the safety equation.
Something similar was undertaken in Australia by Braithwaite (Attitude or Latitude?), I recall that there were differences between civil and military pilots and some surprises when comparing hazards with the ATC viewpoint.
Good luck with what could be an interesting quest.
