Blacksheep - your last comments are perceptive and pertinent. Without top level airline management commitment towards tackling the HF nut the industry will not make the breakthrough in aircraft accident reduction that the CAA and other regulators are looking for. As with safety in other industry sectors such as road, sea and rail transport - the hardware has become more and more reliable, the procedures and information handling systems are developing and improving all the time, but the poor old Mark 1 human being has not really evolved much since the stone age. Airline managers must realise that employees are not robots or production units, but are normal people who make normal mistakes, which within our unforgiving working environment can unfortunately lead to catastrophic outcomes. The aviation industry must start building error tolerant flying systems rather than error inducing ones. The commercial imperative will always mean that companies strive to maximise the productivity of their capital assets and labour. Therefore everybody involved - pilots, cabin crew, controllers, ground handlers etc. are all subtly pressurised to squeeze more and more into an ever shrinking pot. Far from this helping to reduce the numbers of errors made it is more likely to increase them. To overcome this tendency there needs to be a total sea-change in the thinking at Board Level - much as is now going on within the rail sector post Southall and Hatfield. The CAA have published CAP 712 which sets out how airlines should start pro-actively managing safety as a corporate issue and within this arena human fallibility - both at management level and at the sharp end must be taken account of. This however requires dynamic safety leadership from the highest echelons of power within the organisation. Not much of that about.
