Cone of confusion
The Cone of Confusion is a cone-shaped volume of airspace directly above a VOR station where no signal is received, causing the CDI to fluctuate.
VOR Cone-of-confusion indications:
(1) Size of a VOR cone is negligible, meaning that station passage can be used as a recognizable fix?
(2) HSI VOR bearing pointer will be removed when within [...]
