If people were taught this...
I thought everyone was taught this: I was anyway (learned in 2000, JAR syllabus). Pretty amazed to think people are flying around without knowing how to do the performance calcs from the POH: is this really true?
I have also found on several occasions when renting from clubs in the US and in Oz that I have been required to take an open-book (POH) test to confirm I know how to do this, especially for hot'n'high scenarios: presumably many people have to do this from time to time for the same reason?
But I think the problem may be, having learned it is forgotten and people get lazy.
