Around 1996, during the summer, an Air Canada DC-9 captain visited the Transport Canada flight service station in Québec City (CYQB) to receive a last minute briefing on the weather conditions between Quebec and Toronto.

All the passengers were already on board, but the captain had noticed a rapid change in the size of thunderstorms approaching the Québec City airport. Wishing to make the best decision, he requested the latest information on the approaching line of thunderstorms before proceeding with the takeoff.

The weather radar and satellite pictures showed a wall of convective cells that a DC-9 would not be able to go through. It would not fly high enough nor be able to go around the system unless it made a detour through Val-d’Or to the north or the Tennessee to the south.

The captain already knew the consequences of his decision. He nonetheless took the phone and called Air Canada’s dispatch in Toronto, announcing that he would not leave Quebec until the weather was acceptable. He could envision the missed transfers in Toronto for most of his passengers, and their bad mood in face of the lengthy delays he expected in Québec City.

Nevertheless, his decision was made and he left the flight service station satisfied. He knew very well that a line of heavy thunderstorms had often been the cause of accidents and that no aircraft, whatever the size, was safe when dealing with a wall of severe thunderstorms.

The flight service specialists (FSS) were happy with the captain’s decision since, throughout the years, the FSS often witnessed far less commendable behaviour from pilots of all categories. Judgment is the capacity to evaluate consequences, and it is not given to everybody.

1986. It was a beautiful summer afternoon at the Rouyn-Noranda airport (CYUY). The Transport Canada flight service station employees knew that a cold front was approaching and would soon sweep the airport. Until then, it was still a perfect day. Blue sky, light winds. At the time, the flight service specialists (FSS) did not have access to radar images or satellite pictures.

To get an idea of what was coming from the west, we were normally using an Environment Canada aviation weather forecast and the actual weather observations of two flight service stations in Ontario, Earlton FSS and Timmins FSS. Their last weather observation mentioned a wind shift and an isolated thunderstorm. But Timmins was far away and could only provide us with a rough estimate of the situation.

As I was working the evening shift on that day, I checked the wind speed indicator, as a reflex developed throughout the years. What I saw was kind of unreal. The speed indicator’s needle suddenly went from showing few knots to 20 knots, and then 40 knots, hesitated a little then went up to 60 knots and, in a final correction, reached 72 knots, which was about 134 km/h.

Everything was so peaceful around the flight service station. I looked through the window to detect any moving object. At that very moment, the wooden shed normally used by the fuel man passed in front of the station. That wooden structure must certainly have weighted few hundred kilos. The fact that it was moving at a good speed was a clear indication that the instruments were working properly. A squall line was associated with the cold front progression.

Everything that was not properly fixed to the ground started moving. In the next hour, strong thunderstorms going eastward moved in over Rouyn-Noranda. The Val-d’Or airport (CYVO) being located sixty miles east, it was clear that it would be hit directly in about two hours. I called the Val-d’Or control tower so that everyone got prepared for the squall line. That gave them enough time to tie everything correctly and damages were limited.

One hour later, everything was back to normal in Rouyn-Noranda and we profited from an ideal summer night.
