I have gone through the original inquiry report of then Indian Airlines crash and airbus design has nothing to do with it. Brand new machine, unlimited visibility and comfortable morning flight.It is a mirror reflection of SFO B777 crash. In IA crash pilots switched to open descent without realising it and speed kept dropping finally 27 Kts. below Vapp. One pilot switched off his FD without other pilots knowledge. All the time they thought they are in speed mode but no one checked the FMA, there was not a single call about speed by any of them. Finally alpha floor did kick in and also pilots themselves moved to TOGA but they lost their lives because they did it 15 seconds too late. SFO B777 Auto throttle was in thrust hold both experienced pilots never checked their speed and despite much touted moving thrust levers of Boeing they didn't notice that thrust levers were stuck at idle all along, again no call out about speed, speed went 30 kts below Vapp. They also went round but little too late and were lucky to survive. I am sorry but you don't fly approaches like that. Protections are needed for these pilots only. Most pilots won't even experience them in their life time.
