Kollsman Window – Altimeter – Paul Kollsman invented the first accurate Barometric Altimeter wiith an accuracy of a few feet. Prior to Kollsman’s invention, altimeters could only determine an airplane’s altitude within a few hundred feet. Kollsman’s invention was used on the first “Blind Flight” conducted by James “Jimmy” Doolittle proving the ability to fly using only instruments.

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 [...]
