Ok. Yes of course there are many little tricks, "rules of thumbs" etc etc....thank you. What boggles my mind is. For something as important as obstacle clearance in the event of a Rapid decompression there is nothing written defining a procedure to be used. Now before you go off again, I know what I would do I know what half of Pprune would do. What I am looking for is a procedure in writing.
everything is defined in this business, so trust me when the lawyers come looking for the Captain and the answer to their question is, " well we just use a rule of thumb, or we basically guess." You better have plenty of time and money on your hands. I just can't believe there is nothing written even on a Jeppesen chart or manual.....
Thanks all for your input, honestly.
