Another way to skin the cat, where I came up w/ approx 10-12°.
So, this is in complete concurrence w/ above, but since there are fewer decimals you can do it with your weight-on-arse switch engaged
:
- "Lead" radials: 40 radials @ 3 rad per DME (60/1 @ 20DME) is slightly more than 13nm
- ROT for turn radius = 1%GS for 1/2 SRT (25°) gives ~ 6.0nm diameter for 180°
- Divide in half to get ~ 12.0nm ==> 12.5°
- Milk it a a little for the additional degrees of turn (outbound to inbound), yielding something less than 12°
If absolutely necessary, you can do this on the back of a soggy bar napkin...but hopefully you don't need it. And yes, it assumes no wind.
