One that appeared in the accident report was risk appetite quoi?
That's a perfectly good phrase that has been in RAF speak for at least a decade and in industry for far longer, it's nothing magical, simply how much risk an individual or an entity / organisation will face before they feel discomfort with what they're doing.
Some will have less room for risk and therefore they have a low risk appetite, for example a major airline with a high public profile choosing not to do an ad-hoc single flight into Tripoli, and some will have (to use recent PPRuNe Military speak) "Cojones" and will have a larger risk appetite, such as a CAS authorising a squadron to attempt to land a very old VC10 at a short runway such as Cosford. That's risk appetite.
As Roadster says, the current use of something as straightforward and modern day as "Risk Appetite" is no worse than the rather silly and puerile use of old non-words like "Wanque" or "Bolleaux" on this forum.
