(I believe it is something like "Captain you must listen to me")
In my former airline (a major operator based in South East Asia), it's stated as such in their ops manual.Challenge the skipper, if there's no satisfactory response then the F/O has to take over if no satisfactory response after the second challenge.The words "Captain You Must Listen To Me" is emphasised & is the mantra of the CRM course.This is a usefull phrase as it weeds out subtle incapacitation cases (which are the hardest to detect).
So, galdian .... look surprise!
