From Graham Cooper:

> 90 DEGREES is the FUNDAMENTAL ANGLE and PI/2 makes NAVIGATION SO MUCH
> SIMPLER!
>
> 1/2 a RA right! = 45 degrees to the right!

> *******post from 2012******
>
> SIN and COS still work on RADIANS
>
> RA is my shorthand for Right Angle = PI/2 (in Radians)
>
> 1RA = 90/57 degrees/degrees = 1.57 Radians
>
> So RA is usually in Radians but is not 1 RAdian.
>
> RA is actually an angle, 90 degrees!
>
> PI and TAU are too big for the mainstream to conceptualise as angles.

Here a YouTube vid by DavidButlerAdelaide where he presents a coherent case for what you are advocating:

"Pi may be wrong, but so is Tau!"

I expect you are familiar with this, but others may not be. And discussion on this issue would not be complete without considering these points, for whoever may find them persuasive.
