IFR system question

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?

Depends. It's not out of the question that, absent radio navaids or ATC
control, one might just use a GPS. In the US, it's legal to fly IFR in
Class G airspace without the benefit of a flight plan or ATC clearance.
Presumably in even more remote areas, that's allowed as well (assuming no
other impediments to aviation, of course). Even a handheld GPS would
provide accurate enough information for an IFR flight 95% of the time or
better, assuming proper preflight planning.

One could also accomplish the flight the way they did in the old days: basic
instruments and dead reckoning. Of course, in the old days those instrument
flights weren't successful nearly as often as they are today. But I suppose
if you MUST fly, that wouldn't be so much of a concern.

I'm having a hard time imagining a situation in which one MUST fly. But it
seems to me that in such situations, one wouldn't worry too much about the
legalities, and might not worry that much about the safety aspect either.

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.

Its uncontrolled IFR. There is an advisory frequency you report your
position on to avoid inflight mating. Airlines do to today out over the
Pacific but is common in third world countries at lower (non jet)
altitudes.

I think your attitude is racist!
I mean - an advisory frequency to prevent inflight mating in third world
countries?

Really?... I guess it's time to break out the books and do some more
reading, I would have gotten that one wrong on a test. :-)

Actually, I was thinking of an incredible woman I met on vacation in Green
Turtle Cay, Bahamas this summer. She's in her 70's now, but in her day she
flew a Piper Aztec out of Treasure Cay. One of the stories she told was of
a woman going into labor that needed to be taken to a Nassau Hospital on an
IMC night. We sat there for several hours listening to this lady's stories.
There are some really interesting people in this world.

Assuming by "IFR service" you mean separation of IFR aircraft by air traffic
control, yes. There are parts of the US that lack that service.

You hope nobody else is doing it at the same place and time you are.
