Pooleys' CRP6 & CRP9 aren't the same as a Jepp CR type. Biggest difference is their wind side is just a cut down modification of a slide type solution. Jepp CRs use trig. to solve the wind triangle. Slide types, including Pooleys' supposedly CR equivalent, use vector addition. The Pooleys' one seems to be missing some scales on the calculator side eg recovery coefficients etc. You don't get the benefits of a true CR type with the Pooleys job.


APR industries used to also make a Jepp CR equivalent. Not sure if they still do.
