An excellent article by editor Frank Bowlin on ILS technique appeared in the February issue. A small error led to some confusion, and IFR embarked on a quest for accuracy. That quest got stymied with some faulty background. We thank astute readers for returning us to the righteous path. I’ll now clear away all confusion and help you understand in great detail which way the wind shifts, and why.
