Hello fellow members of the Forum:
Today I am going to tell you something that, more than one, can cause you to laugh; and, to me ... honestly, I almost feel embarrassed to raise this term at this point, this qualifier that I have seen almost from the beginning in this Forum and that I never dared to ask, hoping that someone sooner or later would clarify it, but until now it has not been like that.
It is really curious this qualifier because I have been flying between planes very intensely, since 1995 and never in any social gathering or discussion has this qualifier emerged in the conversation or discussion. And it is curious, because I know that my language is very rich in qualifiers. Of course, I've tried it on Google, but Google when it comes to technical jargon, they still have to evolve a lot. However, it is clear that there must be an equivalent qualifying adjective. What is that adjective ?.
Well, then ... less literature and let's get down to business. What is the term or qualifier that I want to clarify ?. This: what is the meaning referred to the condition of the aircraft "cold and dark"?
