Triple W:
It is interesting that you are getting the privilege to do ADF approaches in Boeings neat jet.
The ADF approach was for years the only approach we used in the Arctic, one gets so used to them you never really think of the physics of why the needle does what it does you just fly the thing and experience allows you to recognize when something is really out of whack.
The secret of course is to always be aware of where you are and where the fu##ing thing is headed. If any doubt exists that is what the missed approach is for.
By the way I don't know if you have used the ADF in mountinous regions, it can really get goofy way down in deep valleys, but the D.I dosen't know you are in a valley.
Hmmm a 737 doing ADF's must be fun?

The hardest thing about flying is knowing when to say no.
