Me too, doing the nav exam. What fun that is.
Slide rules were last used by me in 1971.......
This is a belter for your opinion.
The pics in the Nav Manual (Godwin) shows the Pooleys CRP Computer, which is not set up the same as my Transair TSP...........
Example 1.
I set the cursur 10 m,, the the inner to 9.1 as in page 25 of the manual, and the box underneath says altitude not air speed.
Is it me??
