IFR in the 1930's

They flew very effectively on the Adcock range, which was set up across the
nation. This was a aural navigation system in which all that was necessary
was a tunable low freq radio, a watch, compas. and chart (some knowledge of
Morris code
"ADCOCK RANGE - National radio navigation system replaced after World War 2
by the omnirange system. It consisted of segmented quadrants broadcasting
Morse Code "A" (dot-dash) and "N" (dash-dot) signals in opposing quadrants
so that pilots could orient their position relative to a "beam" broadcasting
a steady tone, and a Morse Code station identifier. Using a "build-and-fade"
technique, a pilot could (ideally) pinpoint his location by the strength or
weakness of a signal"
look up adcock range on Goggle.DF was also available.

Staring at my empty instrument panel while considering which
instruments and their placement, I got wondering how old time Mail
pilots flew if caught in IFR conditions.



Mostly, they flew into the ground.
