Most airspace above seas and oceans are not covered by ATC primary radars.

Just for the interested, here's a map showing Japanese military radar, just to get an idea of coverage in a country full of people and planes.Ī lot of airspace is not covered with primary radar, at least not for ATC purposes. It should in theory be well within reach. South Africa has good coverage, and I'd guess the same for much of northern Africa as well.Ī few remote areas in South America, then again, improving.ĭetermining factors are population density, aircraft density and economic development.Īs more you Malaysia map, if there's a radar at Kota Bharu airport, here's the map assuming a range of 200 Nm for the radar. Apparently known as the 'dark continent' for spotty coverage and consistency. Multiple areas in Africa, but this is improving I believe. I'd imagine there are a few holes in the CIS countries as well. I was told though by the pilots that the Americans were keeping an eye on us.

Here are a few I can think off:Īfghanistan, not really what you'd expect from flying between Europe and South East Asia. There are a few spots not covered by primary radar.
