Aviation safety capsule: density altitude
Contributed by Gilles Jean and Smart Pilot

Wow ! 32 C, 40 felt! That means it will be hot and humid. Do you know the impact of this kind of temperature on the performance of your device? If not, you should !

It is easy to imagine the pilot who flies his Cessna 172 every weekend, normally alone, in typical summer conditions and decides to take his two brothers-in-law and his sister for a ride; just a little ride around the airport. If this pilot does not take the time to do small calculations, he may be surprised. And it won't be a good surprise!

The performance of your aircraft depends not only on the engine, but also, and above all, on the altitude of the airport, temperature and humidity. If these parameters increase, the lift, the rate of climb as well as the power of your engine will be less. The only thing that increases… is your stall speed. So in hot and humid weather you lose out on everything.

What does density altitude mean to you? This is the pressure altitude corrected for temperature. Take for example, a Cessna 172R in Thedford Mines (elevation 1408 feet), a pressure of 29.75 ”Hg and a temperature of 32 °C, the density altitude will be 3,842 feet. So this plane will behave as if it is at 3,842 feet. The take-off distance will be approximately 1,550 feet instead of 1,100 feet if the temperature was 20 °C and the distance to clear a 50-foot obstacle will be nearly 2,600 feet rather than approximately 2,850 feet. The Thedford Mines runway is 4,500 and there will be no problem to take off, but in the event of an engine failure, there won't be much room to spare. On a shorter runway under the same conditions with a 100-foot obstacle to overcome, it might not work.

So take the time to think about how your plane will behave before pushing the throttle.

Here is a link to a video which shows a situation where the pilot narrowly escaped such a situation.


Roland Brassard, one of the pioneers of the APBQ has died. 

It is with sadness that we learned of the recent death of Roland Brassard. Several of our readers will have known Roland personally or for others by his benevolent and reassuring voice on the HF frequency 5.275 MHz -  XKV918.

This radio station which is still active today thanks to the contribution of Vincent Charron and his team provides weather information to pilots who venture into northern Quebec, collaborates with SOPFEU and provides a service where pilots can make urgent communications to their loved ones.

Roland's commitment and volunteerism have contributed to the safety of members using the frequency for almost 20 years. We extend our sincere sympathies to Roland's family and loved ones.

A suggestion from Jean-Pierre Bonin

Rémi Girard is appointed director on the board of directors of Aviateurs.Québec.

Michel Chartier, president of Aviateurs.Québec, is pleased to announce that Rémi Girard has recently joined the association's board of directors.

Rémi joined CASARA / SERABEC in 2000. He has held several positions within SERABEC such as observer, direction finding specialist for the ground search team, regional director, regional and provincial training officer. Rémi obtained his private pilot's license in August 1988. He has accumulated 1,100 total hours on a dozen different types of aircraft. He is the owner of a 1947 Cessna 140 and a 1946 Globe Swift. Rémi has been president of the Saint-Hyacinthe pilots association and vice-president of Aviateurs Quebec in recent years, and has served for some time on Aero-Vision. He has participated on several occasions in the organization of the annual Lobster dinner.

Rémi is now retired after 38 years of service at Videotron and has held various positions there, including that of director of purchasing.

Rémi is passionate about aviation and devotes himself ardently to his involvement in CASARA / SERABEC. He is a team player, and his motto is "alone we go faster, but together we go further".  Rémi firmly believes that the development of the skills of SERABEC members involves sharing knowledge and delegating roles and responsibilities, it is the only way in his opinion to ensure the succession of the search and rescue organization. air.

In addition, Rémi believes that the advancement of general aviation depends on the involvement of those interested in helping out, preparing the next generation and recruiting young pilots to join Aviateurs.Québec.

Welcome to Rémi.

Maurice Prud'homme is named honorary member of Aviateurs.Québec

We are pleased to announce the appointment of Maurice Prud'homme as an honorary member of Aviateurs.Québec.

The board of directors of Aviateurs.Québec thus wishes to underline Mauritius' commitment to the promotion of general aviation through its annual winter meeting at Chez Moe's. These are 32 editions that Maurice has organized bringing together here over the years thousands of visitors to this RVA. After his last RVA in 2020, Maurice decided to retire as the organizer of this event. We will remember his warm welcome, the flawless organization of his event and his famous chili.

On behalf of Aviateurs.Québec and all your fans, thank you Maurice.

The Quebec government air fleet charter management contract awarded to a firm outside Quebec.

Our Ministry of Transport recently awarded an on-demand performance contract outside Quebec, for “Routine aircraft charter operations services for government missions” when we had everything back home to  do it. Once again, the rule of "Low Bid Cost / Lowest bidder" has demonstrated the rule of lack of good judgment.


Circuit offered at Trois-Rivières airport

The management of Trois-Rivières airport wishes to make its users aware of the procedures proposed for noise reduction. The map above shows the sensitive areas as well as the restricted area of the Trois-Rivières prison.
