automatic direction finder


Definition of automatic direction finder

: a navigational tool that continuously displays the bearing of a designated reference radio beacon But unlike some other relics, the ADF (automatic direction-finder) keeps rearing its ugly head like an uninvited relative who shows up at the family picnic. Instrument pilots who try to fly without a good foundation in ADF needlework can quickly run smack into an indigestible hash of headings and bearings.— Thomas H. Block, Plane & Pilot, January 1994 abbreviation ADF
