Jabawoky, if you are suggesting ignore the aircraft flight manual, in this case, what other parts of the manual should we ignore? Procedures are everything in this industry.
Furthermore, if you have a degree in engineering, industrial chemistry, tell Pratt, Textron, or Continental they are wrong. Their engineers would love to hear from you.
If you are not an expert, why comment at all. Hell, I don't surf the dentistry forum that that very reason.
