Sitting in the club at the weekend whilst a Nav ground school was going on elsewehere in the building, I spoke to the instructor who was lamenting that a whole morning had been taken up on the crp thingy. Now, somewhere there must be a heap of these things junked the moment the exams have been passed, only reserected by those going on to more exams. No one it seems uses them in anger. In these days of calculators, they should be dumped. Ok they are clever, but they are a total waste of time money and effort and add nothing to flight safety.
What thinketh thou fellow ppruners, does anyone use these things?
