ADF needle "dip"
this occurs when tracking an ADF Needle which Dips toward the side of turn, ie bank right and the needle will "lead" into the turn which if not anticpated will cause an overshoot which now requires a correction the other way. Lots of guys know it happens and call it "Dip" or "Quadrantal error" or "turning error" and anticipate by rolling out early
anyone have a technical explantion of why this occurs ?
no publication i have been through (AP 3456 and various commercial items) says anything about it at all.
its certainly woke up our instructer Cadre here but no one knows WHY
to sort out terminolgy its not quadrantal error (signal bending caused by airframe) or dip as in near a pole or beacon.
it seems to be independant of range but dependant on relative bearing ie most anticpation required if ADF is on the nose or tail and least if its off the beam.
any help of interest
