CRP5 Issues
I know it has been asked before, but not recently it seems. I have a Pooleys CRP-5 on which the slide rule (wind) part is really stiff. Unscrewing the screws doesn’t make a difference, and also I find that the Wind calcs and some other numbers it produces are always slightly different to the correct answers (and I am using it correctly). Question is, can I use the Transair equivalent with the Wind Arm in the CAA/EASA ATPL exams these days, should I try another type (that can be used in the exams) or just accept what I have and the shoddy results it produces? Thanks in anticipation.
