Gnads I agree a physical takeover by the F/O can be problematic BUT if hot and high and WILL land well down the runway, probably overrun and (probably) kill people what other option exists for the F/O if making calls has not succeeded??
Ask the dead from AIExpress in Mangalore some 10 years ago, sure they would have appreciated the F/O taking over but he didn't.
But it's written in the book...what more can we do??
Used to be when there was an endemic problem you'd try and fix or improve the problem, not so much these days.
Cheers
