I do find it worrying that you have any involvement in training, you don’t seem to grasp the very basics of flight safety.
Firstly it is surely blatantly obvious to nearly everyone that the training, checking and SOPs were inadequate to prevent this accident. Otherwise, it wouldn’t have happened. To put it politely, “Duh!”.
Secondly you appear to have some fantasy that these things are black and white, or “binary” in modern parlance. Either something is safe, or something isn’t safe, adequate or inadequate. No middle ground. Which I find amazing and scary.
With the training regime extant at the time, people were accustomed to flying an onshore NPA in various different ways with various different upper mode engagements. There was no standardisation simply because there was no laid down standard to adhere to. Yes Ok nearly everyone coped with that, but being accustomed to using VS mode during an NPA with speed reduction was an accident waiting to happen. So not surprisingly it eventually did happen when the cheese holes lined up, especially when there was no proper stabilised approach policy either.
Of course they made a mistake and failed to control and monitor the speed. But we need to bear in mind that humans (of which group most pilots are allegedly a member) make mistakes. They do, so get over it! (Apart from you, obviously). Because we know that humans make mistakes we need to design error-tolerant procedures so that when they do make a mistake, and they will, it isn’t catastrophic.
Hmmm, let me think how could we make flying a NPA error tolerant in terms of airspeed control? Oooh, I know, let’s make the pilots use IAS mode! There, the problem is solved in an instant and the accident won’t happen again. Quite easy really, wasn’t it! Just a pity the company’s SOPs didn’t require that and lots of people were in the habit of not doing so. That cost 4 lives.
HC your tiresome and bigoted attacks on me with your very anti-military standpoint don't do you any favours and certainly don't make any case for changing my mind about this accident.
