AW139 G-LBAL helicopter crash in Gillingham, Norfolk
Risk assessment- is what every pilot does before any flight. If it's paper based then it demonstrates that someone has actually done the math and concluded that on balance it's safe to fly. However, objectivity is required and it is easy to input values which give the result you require. If a proper, objective RA is completed prior to flight then this would demonstrate the exercise of reasonable care and diligence. Where the values ascribed to variables had been manipulated to reach a desired outcome the opposite may be true. The difficulty with this process is the human factor. Perception if risk is subjective, the requirement to ascribe values to each of many variables may not actually achieve the correct outcome. One man's pea souper is another's low cloud with marginal vis. It does come back to the old vs bold factor.
