Iqaluit FSS and the sleeping pilots

In the early 1990s, I was working at the Transport Canada flight service station (FSS) in Iqaluit, providing air traffic services. While I was in charge of the HF radio communications allowing the tracking of transoceanic flights, I received a call from a controller asking me to try to contact an airliner of a big European company.

Their pilots had crossed 60 degree west without communicating with Iceland radio and it was now necessary to ensure that the projected passage time for 70 degree West and the altitude of the aircraft were still valid.

I tried to communicate with the crew using all means at my disposal, among which the SELCAL system which sent an alarm signal on board the aircraft. Nothing worked. Other airliners flying nearby the aircraft were requested to help by trying some calls on VHF emergency frequencies. But again, there were no replies.

Suddenly, about one hour after the moment that the pilots should have given some sign of life, I received an answer to my repeated calls. I told the crew that all the efforts had been made to contact them but without success. I asked them an official position report and an estimate for the next mandatory point of contact. Calmly, the pilot answered that he did not know why I had not received his calls and he immediately prepared an official position report.

It was kind of strange that on a day where the HF reception was excellent, and when all other companies were communicating with Iqaluit radio without any problem, this company stayed silent for such a long period of time.

I finally received the new position report but it clearly looked like an invention. If the data provided by the crew was correct, this aircraft would successfully fly 400 nautical miles in the next ten minutes. It would mean that at this speed, the crew expected to cross most of Canada in about one hour.

I advised the pilot to redo his calculations since, visibly, he seemed to have no idea of his position. He came back with new numbers, very different this time, which match what was expected.

I guessed that during the long transatlantic flight, both pilots slowly fell asleep while the automatic pilot kept the aircraft in flight. Suddenly woken up by the multiple calls, the crew did not take into account the movement of the aircraft during the hour where everybody was asleep and, worried not to get caught, rapidly transmitted totally erroneous calculations.

Nonetheless, the story ended well since the crew, now rested, provided exact information for the following position reports, allowing for a safe flight until destination.

Canada: Iqaluit FSS and the 1989 solar storm

1989 was a problematic year for the Transport Canada flight service specialists (FSS) in Iqaluit as we had problems communicating by means of HF frequencies with airliners crossing the North Atlantic.

As usual, we tried to get position reports at 60, 70 and 80 degree west in order to ensure that the Montreal, Gander, Winnipeg and Edmonton area control centers could provide accurate air traffic services by maintaining ten minutes or eighty nautical miles between each aircraft. We had to note the route, the actual and next position of the aircrafts, the different time, speed and altitude, this while we relayed ATC clearances.

But for many weeks in February and March, the radio communications were blocked by a solar storm that was strong enough to cause problems to the Hydro-Québec electrical network. The entire province of Quebec suffered an electrical power blackout that lasted nine hours on March 13th.

During a major solar storm, the full spectrum of HF frequencies can become useless for frequent periods varying from ten minutes to an hour.

I remember several problematic cases, among which one where an area control center controller asked us to contact an airliner to know if the pilot could climb to 37,000 feet once at 70 degree west. The question was transmitted to the pilot and he immediately replied: “Roger, we are climbing 370”. He had not received any clearance to change his altitude but he was nonetheless starting to climb where there was no adequate separation between him and other aircrafts.

We replied multiple times: “Negative, this is a question, this is not a clearance, do not climb to flight level 370”, but the pilot never replied back due to the poor quality of HF communications. The control center was quickly called back and advised of the situation.

For the remaining period of the solar storm, the flight service specialists were asked about the actual quality of the HF communications before any punctual requests was sent on radio in order to avoid problems.

Iqaluit FSS and the Persian Gulf War

In August 1990, Iraq invaded Kuwait. This invasion was unanimously condemned, even by countries that are traditionally aligned with Iraq. The United Nations reacted by giving Iraq up to January 15th 1991 to withdraw. But Saddam Hussein’s attitude clearly showed that there would be no withdrawal and that he intended to proceed with Kuwait annexation to the Iraqi territory.

Understanding that military force would obviously be necessary, United States (representing a coalition of 34 countries) started preparing for the conflict. Aircraft movements increased and short range military aircrafts that would have to cross the Atlantic used Iqaluit, on Baffin Island, as a stopover before continuing through Greenland, Iceland, Europe and finally the Middle East.

Starting summer 1990, the Iqaluit airport then became one of the mandatory stopovers towards Middle East for some military aircrafts. Soon we could see L-382s carrying large size items and some OV-10 Broncos painted with desert colors landing in Iqaluit. Later on during autumn, other specially equipped aircrafts like the U.S.Army RU-21 Guardrail Common Sensor also made stopovers in Iqaluit.

A Southern Air Transport L-382 also landed in Iqaluit. That company was sometimes used by the CIA for its operations.

As soon as a flight service specialist (FSS) was not busy with radio communications, he would head toward the briefing counter to receive the military pilots who had come to obtain the mandatory weather and flight planning information that would be used to safely cross the Atlantic.

HF frequencies used for international communications at the local Transport Canada flight service station were really busy. On top of the regular air traffic services normally associated with commercial aircrafts crossing the Atlantic, we were now dealing with the radio communications associated with numerous military cargo aircrafts like the C-5s Galaxy and others.

In the two weeks preceding the United Nations ultimatum, between January 1st and 15th 1991, the Iqaluit flight service station recorded a 266 % increase against the same period in 1990 in oceanic traffic transiting through its airport. Flights were mostly related with private or chartered business jets linked to international banks, petroleum companies and military organizations preparing for the events to come. We received, among others, aircraft types like the G1, G2, G3, G4, HS25, DA50, DA90, CL60, C550, LR25 and B-727.

One night of January 1991, while we were at work, one member of the staff took-off his headphones and calmly told me: “Son, the war has started”.

I will remember that special period since we did not receive a military training but, nonetheless, we witnessed and dealt with the preparation and aircraft movements associated with a major military conflict.

Moreover, for a short period, the Iqaluit airport reverted to the use it had initially been planned and built for in 1942, during the Second World War, which was a base created for short-range military aircrafts heading to Europe.
