laurie,
I think what SC is refering to is the many hints which are printed on the CRP5. Can't remember how many ticks to move the compressability window? No problem - the formula's printed next to the window. Can't remember whether the index on the wind side is track or heading? Printed next to the index is the word "heading", which is what you'll put there if you use the wind down method. Can't remember which speed goes on the inside and which on the outside when converting from IAS to TAS? Well, it's marked on the wheel itself, just look for the marking. And so on...
But that's no substitute for practicing enough that you can use the whiz-wheel without thinking about it. Time is quite tight in some exams, and if you spend 10 minutes having to figure out how to use your CRP 5 in the exam, you won't have time to finish.
