so-pilot's only thanks-
do we really think, that on a Max Flex/Red thrust (Airbus/Boeing) take-off, at night, we can differentiate/identify correct acceleration for
-a 3700m runway
-a 3500m runway
-a 3900m runway with a second segment limit
-a 3200m uphill runway with tailwind component
etc etc.
Of course we can't. The only reality is staring at the red/whites and knowing you need to be airborne -soonish!
Regardless.
This crew responded to an impending threat
So forget the 'perception/should 'ave caught it/ rule of thumb', theories. The only thing that 'got 'em' was an input error.
Now- if you read back an altitude, and wind in something else in the window,you have a potential breakdown in separation=potential collision. However, there are still a couple of protection levels available (TCAS, ATC).
Typing in an incorrect weight has only one error trapping mechanism- the other pilot.
Some more work needed here perhaps?
Like many others here- I feel for the crew.
And perhaps EK need a gentle 'Taser up the Rear' to re-define their culture.
At the moment, despite nice new kit, flashy terminal, they are looking rather shabby.
No offense to the highly professional line aircrew there.
Cheers
