DreamLand, your attitude worries me: "if it complies with the letter of the law it's irrefutably safe, even if the Captain thinks it isn't".
I'm only SLF, but it seems to me that in this respect aviation isn't that different from other areas of life, where legislation provides a minimum general safety level but the circumstances of a particular case might make something that's legal quite unsafe. 50mph on a snowy country lane, for example.
I'm much more inclined to say "if it worries the Captain it worries me, whatever the regs say"
