DOVES, careful how you make your points; I hope that I have not misunderstood.
Knowing that something is dangerous is an essential starting point, but it is the personal knowing at the time that the hazard which determines the threat – it has to be recognised and action chosen.
The choice (the forbidding) does not come from someone else – SOP dependency, it’s you who has to consider the circumstances and apply personal rules – the ‘forbidding’ is guidance – does the SOP know if hail has been detected or not, etc.
Inconvenience, no; it was a choice of action. We can assume that the decision in this instance was made with the evidence, beliefs, and knowledge at that time (if not why not), thus all such decisions are good. It’s only with hindsight that decisions are categorised, good, poor, but not ‘wrong’, only opportunities to learn and improve.
If the inconvenience reoccurs then it’s another opportunity to learn; it’s not for the industry to point at the crew and suggests more training. Such action is no more than blame and train; perhaps the industry, other operators, and pilots might learn from such experiences.
