The North-South air traffic control link

1

After this week’s decision by North Korea to stop answering a military hotline between border control posts at the Kaesong Industrial Zone, there remains just one known link through which North and South Koreans can still directly speak: an air traffic control connection between Seoul and Pyongyang.

The connection, a vital safety link for air traffic overflying the two countries, was first opened in 1998 when the DPRK opened its airspace to overflying aircraft. Before then, aircraft had to fly around the country and that meant longer flights and higher fuel consumption. Opening North Korean airspace was estimated to bring savings of $125 million a year for airlines at the time.

Last year, I wrote about the satellite link between Pyongyang and Beijing that was installed by the International Air Transport Association (IATA) when the DPRK was brought into the Asian regional air traffic control network.

There’s some history in that article, but I recently stumbled across the transcript of a speech given in 2008 by former IATA Director General and CEO Pierre J. Jeanniot that provides a bit of the backstory.

It all started when Air Koryo expressed an interest in joining IATA. As IATA members stood to save money and fuel from access to North Korea’s airspace, Air Koryo’s application provided a way for discussions to open with the government in Pyongyang, said Jeanniot in the speech.

Getting the North Korean government to approve was one hurdle. A second was the out-of-date air traffic control center and a ban on communication with South Korea.

When the talks began, IATA discovered it had another advantage, said Jeanniot:

An additional factor in our favor … was the fact that North Korea was rather short of foreign currency … particularly US dollars … and they had not been aware that air traffic control centers … guiding airplanes through their airspace … could charge an appropriate fee … and thus earn valuable foreign currency. — Pierre J. Jeanniot, AGIFORS Symposium speech, September 26, 2008.

IATA explained to Pyongyang that it could earn foreign currency by opening a few well-defined corridors for aircraft that would pose no security threat for the country. Jeanniot said in the speech that IATA offered to advance the money, train air traffic controllers and modernize the control center.

That solved the first of the problems, but the lack of communications remained.

To overcome this particular constraint … IATA offered … – and subsequently received authorization –… to set up and operate the telephone lines between Pyongyang and Seoul … so that North Korea could continue to feel that they had not established any link with South Korea.  — Pierre J. Jeanniot, AGIFORS Symposium speech, September 26, 2008.

From a presentation I received some years ago, here are a couple of pictures of the North Korean air traffic control system upgrade and the phone connection.

How satellite helped open up North Korea’s airspace

1

Back in 1998 the International Air Transport Association (IATA) improved its network connection into North Korea by linking the country’s air traffic control system via satellite.

The link, via Asiasat 2, was outlined in a presentation that was sent to me soon after. I hadn’t been able to find it for years, but just located a copy in an old email archive. While old and out-of-date, I thought there might be some interest in presenting some of the information here, and providing a bit of history:

Attempts to open up North Korea’s airspace began gathering pace in the mid nineties. Flying over the country rather than around it would allow airlines to cut costs and shorten travel times on some Asian flights. It also stood to make money for North Korea in overfly charges, but the country would require an upgrade to its air-traffic control system.

In August 1996, IATA announced North Korea would open its airspace to all flights from December the same year. Negotiations had been going on since early 1995 and the deal was expected to save airlines $125 million.

At the time, a spokesman for the DPRK’s General Bureau of Civil Aviation told KCNA:

We officially expressed our stand to allow all civil aircraft of the world to pass through our airspace a long time ago.

And we joined the international air passage agreement in January last year.

Accordingly, we and the International Air Transport Association have discussed and agreed on some practical measures to guarantee aircraft through our airspace.

The International Air Transport Association announced on 2nd August that the DPRK will allow all international civil aircraft to pass through its airspace from December this year.

This is patent proof that our measures to open the airspace are being promoted in real earnest at the practical stage.

Now the International Air Transport Association and all the civil aviation companies of the world warmly welcome this as one of great events in international civil aviation, adding that passage through the DPRK airspace is economically effective as it would lessen the time of flight by far, reduce the consumption of fuel and help save a lot of expenses.

Some dishonest forces are spreading false rumours about our measures of opening the airspace for the sinister political purpose of slandering the DPRK, but they will only be ridiculed and scorned by the international community. We are doing our best to promote convenience in international civil aviation and will welcome and actively help the passage of all civil airliners through our airspace. — KCNA, August 12, 1996.

But by late 1996 a firm deal had yet to be reached and the date was shifted to 1997. Talks continued and in September 1997 the DPRK finally reached an agreement with South Korea on air-traffic cooperation. Communications between the two sides had been a key sticking point.

The Associated Press reported at the time:

In talks that ended Wednesday, the two sides agreed that their air traffic control towers will communicate through surface telephone lines crossing the border.

North Korea tends to avoid direct communications with the South and had insisted on satellite connections. The only direct communications link so far is a Red Cross hot line. — AP, October 8, 1997.

North Korean airspace finally opened on March 1, 1998, when a Cathay Pacific cargo flight overflew the country. A couple of days later a Korean Air cargo jet made the same flight then a month later a Singapore Airlines flight from Hong Kong to San Francisco became the first scheduled flight.

But it wasn’t opened to all:

The US Government, however, will still not permit US airlines and US-registered aircraft to overfly the North Korean mainland. — Flight International, July 22, 1998.

The IATA project to upgrade the DPRK’s air-traffic control system had been going on at the same time, as detailed in these slides:

The project linked five domestic air-traffic control centers, Pyongyang, Sondok, Orang (Chongjin Airport), Samjiyon and Sonbong, with four regional centers in Daegu, South Korea; Shenyang, China; Vladivostok, Russia; and Tokyo, Japan.

Here’s a map of the locations in North Korea that were connected:

And pictures of the installation:

 

IATA performed a second update in 2002 with the installation of a new radar facility (called an MSSR or Monopulse Secondary Surveillance Radar):

Before the installation of the MSSR, Russia’s ATC authorities limited traffic entering and leaving North Korean airspace because of the need to transition aircraft to and from metrically calibrated Russian airspace. North Korea uses non-metric ICAO standards. – Flight International, 10 December, 2002.
