Mid-Air Collision Near Ottawa

Bottom line....if the Cessna pilot had taken the time to use his installed radio, he'd probably be alive today. Something to think about.

I would never consider the visual scan as a saviour of mid-air collisions. If you've ever flown a low-wing twin at an ATF airport, you're probably well aware there are a ton of blind spots when joining the circuit and while a scan is possible, it takes a lot of concentration. While I make sure to scan as best as I can, I still get surprised by the occasional NORDO aircraft, which thankfully has never been dangerously close, but still unsettling to spot when you weren't expecting it.

Let's be honest, during cruise you're not constantly looking outside, and even when you are, you're probably looking down at the roads, at the weather, the nearby towns, lakes, etc.. monitoring your track (or staring at a Magenta line, you lazy bugger). See and avoid seems to work best when you're actually expecting to see something you need to avoid.

Ever tried to spot an aircraft during sunrise or sunset? What about on a hazy day? How about when the sky is overcast and there's snow on the ground and the opposing aircraft is white? Even with flight following, when Centre points out traffic nearby, I'm alarmed at how hard it can be to spot at times, especially those thin, sleek little GA aircraft.

NORDO seems insane to me.

"Neither pilot saw the other aircraft in time to avoid a mid-air collision, partly owing to the inherent limitations of the see-and-avoid principle. Relying solely on visual detection increases the risk of collision while in uncontrolled airspace. Pilots are strongly encouraged to broadcast their intentions while in an ATF area in accordance with TC's VFR communications procedures, even though they are not mandatory."

Well we waited for the report, and it doesn't get much clearer.

Proper radio work likely would have prevented this accident.

If radio calls are considered that primary to the TSB, why are NORDO aircraft even legal?

Basically because the TSB can't tell TC what to do otherwise it likely would be. I'm sure the TSB's primary objective is to minimize risk as much as possible and obviously flying NORDO adds an additional risk factor to flying.

Don't see why TC won't mandate handhelds....anyway I suppose irrelevant to this accident. Wonder if the radio wasn't working....seemed that wasn't clear? Possible if it wasn't transmitting, how would the pilot even know?

Looks like TSB released the report. Blames it mostly on no radio calls coming from the Cessna. Also looking to mandate flight recorders in GA aircraft.

So, pilot joining circuit doesn’t hear any radio calls, figures he’s alone, doesn’t bother doing a proper lookout, turns downwind, runs over other aircraft.

Also, pilot on downwind doesn't see aircraft twice the size of his approaching from the left and then runs into it and dies.

Dude, what is with you? Why do you want to blame only one of these two people?

And you know that radio was functional and transmitting, how exactly?

It is possible that the radio wasn’t transmitting on frequency due to a fault or was known to be not working but the pilot decided to fly anyways(which can be done legally) or was transmitting on the wrong frequency, etc. A lot of pilots do a radio check with Unicom prior to departure where possible or with another aircraft (if possible) when no Unicom is available.

Buds, I think we are both on the same page; people need to be looking out. It still sounds to me like the faster aircraft ran over the 150 (given the description of events and the damage on the aircraft) but I really don't want to let that argument distract people from the main point here. Scan-the-@#$!-outside.

From the TSB report...the Cheyenne and the 150 were on perpendicular tracks. Neither saw the other. Multiple statements indicated that the 150 pilot wasn't transmitting on the ATF. The Cheyenne didn't run over the 150, they collided.
