I'm not a pilot, just a controller. I've read every post on this. Do you think it might be expedient in the short term to do away with the "160 to 4" with a view to stabilized approach further out and at greater height ? I refer to comments about power reduction at "4" and then power demand after speed shedding.
I repeat that I'm not a pilot, but maybe ATC can help if it is considered to be worthwhile as an interim safeguard during the investigation cycle.
No, leave it as it is. They were in a stable approach at 600'/2nm. In my opinion, it would have made no difference it they were at 1200'/4 or 2400'/8.
Maybe the fact that they were not stabilized until short final is what saved them from landing 2 miles short instead of 2000' short.
Think about it.....
