Small parts of the US I assume in Navada and near Idaho. Northern Canada?
The poles, outback of Aus. Western and Northern part of China. I heard a lot of SA but Im not sure. Pilots have to give position reports using HF radio or VHF. I heard once that a pilot gave a wrong position. The plane crashed and it took days for them to be found. Happened in SA.
Also there is no radar coverage in almost all of Africa and Siberia.

Speaking of Siberia, I read an article about Aeroflot ops to Siberia in Flying Mag some times ago. The cockpit crews consist of Captain, F/O, F/E, Radio Operator, and a Navigator. What a crew composition!

Those are very old aircraft. All new aircraft use INS and GPS so there is no use for a navigator or a radio operator. F/E have been eliminated and replaced with advance flight control computers. Old aircraft used all 5. Not only in Russia but the combo was used for oceanic crossings as well.

Yes, indeed. The writer jumpseated in Aeroflot's 757 (or 767?) from New York to Moscow. Then he jumpseated again in a russian plane to siberia with those crew compo. I believe he wrotes the article sometimes in near 2000s.

North America generally has good radar coverage, entire USA, Southern part of Canada and Mexico/Carribean...
South America has rather poor coverage in its "Northern" parts... Brazil has full coverage drom the NE corner through Southern borders, but poor over the "Amazon basin"... Southern South America has good coverage, Chile, Argentina, Uruguay are excellent...
Africa is ... do we need to say what... inexistant except South Africa...
Europe, full coverage except some areas of Balkans... European Russia and Ukraine has full coverage...
Middle East, poor, except Saudi Arabia, and the "Gulf Area - UAE - Oman"...
Asia, poor everywhere, except Japan, South Korea and Taiwan...
Australia, good coverage from NE through South...
Did I forget any corner of the planet...???

Most of Indonesia's area are covered by Radar Service, (at least western part of it), but controllers tend quite lazy in providing adequate service. They still want us to give position reports and estimates. They also not quite organized among themselves.

I wonder how nobody mentioned the atlantic routes...radar coverage is even nowadays thin to nonexistent and the ATC's have to use procedural control to cope with the traffic.
This was also the reason why the Il-62 has a crew of five - it was built primary for transpolar/transatlantic/transsiberian flights, and as well as on the atlantic routes as in siberia navaids are almost not present. And, remember, it was designed in the mid-60's, so definitively INS was NOT an option for navigation. The DC-8's/B-707's of these years had a built-in sixtant for navigation on such routes, and there was a rule that either one of the crewmembers must hold a full navigator license or there must me an extra navigator onboard when flying transpolar routes for example.
