1-60 Rule
 
Hi,I`ll try and have a go:}Thinks it 1nm made easy being 60nm
60nm brings 1-60 to mind.You know your 2 degrees off from the CDI.
For future questions did it like this.
Lots of people use the whiz-wheel but for the written exams i wrote out a
Formula: dis gone/dis off x 60 + dis to go/dis off x 60=c.a.
Kind of makes sense "gone" then what you have "to go"
You only need to use the first part,ie using track error.Which is 2 degrees!
Now solve by moving the formula around and you see it equals 2nm off i believe.By canceling the 60`s out.
Is this the correct answer???

I thought a 1/5th deflection on the cdi equals 2 degrees? At 60nm, 2degrees = 2nm course centreline deviation?
