Rookie question: Are there parts of the world that don't have IFR
service such as Africa and Siberia etc? If so, what does one do if
you must fly and IFR conditions prevail?

As early as the 1960's, I was flying B-707s on IFR flight plans over
most of Africa. As a backup to the ATC system, we pilots monitored
a common VHF frequency and broadcast our position and intentions in
the blind to anyone in the area.

Up until my retirement in 1991, Haiti remained about the most question-
able ATC system that I encountered.
