Barit old boy I can barely read enough to type these days so if you have something to add about what you did with that test machine you used to tout around please tell me. That thing must have had some temp guages on it. If not then STFU. What your dad did in WW2 has no bearing on what you did with your career.
Caad Thank you. Of couase I am NOT suggesting RR fraudulently offered false data. They may be incompetent engineers and pass the odd buff envelope around when soliciting business with foreigners....but data fraud NO!
"Oil temperature is specified on the Engine Type Certificate Data Sheets which are easily available online. Well, the CAA ones are, EASA not so easy. FAA probably easy."
Oh really?
The issue is that any oil will begin to vapourise above 150C. This is a valid question of interest and I would be grateful if the more generous members of this forum would tell me what they see on their guages.
