Quoting crazyfoo88 (Reply 1): Appears to be LOF3363, and runway 32 seems to be the approach used. |
Quoting YYZatcboy (Reply 4): Perhaps this is a sign that the runways in YOW need some work done on them. |
Quoting Salukipilot (Reply 5): Hmm well Canada seems to have not got the hint about grooved runways. It's not even that hard to do. |
Quoting YYZatcboy (Reply 4): So how many planes have now gone off the runways at YOW. Something like 5? |
Quoting JBirdAV8r (Reply 9): Bingo. Almost none of the runways in Canada are grooved...unlike most developed countries. All the incidents at YOW, the Air France A340 at YYZ.... |
Quoting YYZatcboy (Reply 6): We don't do the grooved runways supposedly due to iceing. It may have helped here, but it's curious that the overruns seem to happen at YOW more often than at other airports up here. |
Quoting YYZAMS (Reply 14): Just like last time this happened, people (mainly those from the southern US) will point out about the lack of grooves. We actually have 4 seasons up here. |

Quoting YYZAMS (Reply 18): The policy in Canada is not to cut grooves because they provide no extra braking power in winter, and they require snow plows to use Teflon blades to avoid tearing up the grooved runways. That makes snow removal expensive and slow. The United States, however, has been pressing world government bodies to require grooving because it makes braking power much better in summer rainstorms. The issue is before the International Civil Aviation Organization in Montreal. Was in raining in YOW when it happened? I gather that grooved runways are only useful during rainstorms? |
Quoting Salukipilot (Reply 5): Hmm well Canada seems to have not got the hint about grooved runways. |
Quoting YYZAMS (Reply 14): Air France had nothing to do with grooved runways. |
Quoting diamondflyer (Reply 15): Why Canada can't join the modern world and groove their runways is beyond me. |
Quoting YYZRWY23 (Reply 23): While grooved runways do make the runway safer in heavy rain, they make snow removal more expensive, plus the cost of grooving the runways (not sure what that is). I am not sure of the history behind grooved runways, but I am sure pilots landed aircraft on runways without grooves for a long time before they were...it isn't an excuse. |
Quoting YYZRWY23 (Reply 23): Simply put: Canada has more winter weather then summer weather. Improved braking in winter conditions are more important then improved braking in summer conditions. I understand that the United States has a large portion of their runways grooved, which I am sure cost a lot. How much debt is the US in again? |

Quoting JBirdAV8r (Reply 9): Bingo. Almost none of the runways in Canada are grooved...unlike most developed countries. |
Quoting diamondflyer (Reply 15): So do many of the US airports in the north, some of which are further north than Toronto |
Quoting apodino (Reply 24): DTW, and BOS are all airports that get plenty of snow and have grooved runways. |
Quoting Ychocky (Reply 16): I've noticed that Trans States will request, nay, demand Runway 32 if there's any sort of shower in the area after the last incident. |
Quoting GoBoeing (Reply 20): I noticed absolutely no difference between the speed of runways being plowed in Canada vs. anywhere in the US that receives any appreciable amount of snow each year. DTW in particular stands out as doing an awesome job |
Quoting YOWVIEWER (Reply 26): Reminds me of Rick Mercer in Washington. |
Quoting kaiarahi (Reply 28): Duhh - dunno what I was thinking. That'll teach me not to post before I've had coffee. |
Quoting kaiarahi (Reply 25): Oh dear, geography strikes again. Please look at a map and name one (outside Alaska). |
Quoting MikeCT (Reply 27): Pretty much all of Minnesota, North Dakota, most of Idaho, Oregon and all of Washington. |
Quoting kaiarahi (Reply 25): Oh dear, geography strikes again. Please look at a map and name one (outside Alaska). |
Quoting MikeCT (Reply 27): Really? Pretty much all of Minnesota, North Dakota, most of Idaho, Oregon and all of Washington. |
Quoting YOWVIEWER (Reply 26): Even without thrust reversers, should the EMB145 not have had ample runway - grooves or no grooves ? |
Quoting kaiarahi (Reply 25): It's not just about the amount of snow. In winter in TC/FAA/NASA/NRC studies have found that ice in the grooves acts as a catalyst for further icing extending outside the grooves. The conclusion has been that it's better to land occasionally on a wet runway in summer than to have every single flight landing on an iced runway for 3-4 months in winter. |
Quoting cyeg66 (Reply 30): Hey, thenoflyzone, slow your planes down on final, for cryin' out loud! They keep leaving the runways! |
Quoting thenoflyzone (Reply 29): They will not land on 7/25 if it is wet. The problem is, they choose a wet runway 14/32, with a crosswind component. Don't know where the wind was blowing from yesterday, but that could be part of the problem now for LOF at YOW. |
Quoting apodino (Reply 34): he said that based on where the plane ended up in relation to 14/32 he thinks this was caused by improper crosswind landing technique, though I am not going to speculate. |
Quoting apodino (Reply 34): That could have been prevented if they had just landed on 7/25 in the first place. 8000 feet of runway is plenty to stop an ERJ on a wet runway, thrust reversers or not, grooves or not. |

Quoting ac888yow (Reply 39): It is resting on the West side of and perpendicular to runway 32, at approximately the Kilo taxiway (around where 140.4 degrees is indicated on the chart). |
Quoting thenoflyzone (Reply 33): When you deal with an airline like LOF whose callsign is "waterski", what do you expect.... |
Quoting thenoflyzone (Reply 33): As for keepin' em fast on final, you know me better than that ! Having trained with ER ohhh way back when....."low and slow" becomes your motto.... |
Quoting kaiarahi (Reply 25): Quoting JBirdAV8r (Reply 9):Bingo. Almost none of the runways in Canada are grooved...unlike most developed countries. That's because the noise of grooved runways frightens the kids in the igloos. Unlike some developed countries, Canadian pilots do not seem to have difficulty landing in rain. |
Quoting JBirdAV8r (Reply 42): According to Transport Canada, your country has had almost three times the rate of runway excursions of the United States and twice as many as the rest of the world (0.25 accidents per million landings, vs the US' .09, and the world average .16) Furthermore, they have found that having grooved runways reduces overrun risk by 75%. |
Quoting cyeg66 (Reply 43): You're kidding with all this, right? Do you not see (more than) a few flaws in the way you interpret this data? If not, it's pointless to discuss further (though I'm sure others will gladly take the bait). Nationalism? Pffft! |

Quoting okie (Reply 40): just simply carrying too much speed trying to get to a taxiway |
Quoting JBirdAV8r (Reply 42): they have found that having grooved runways reduces overrun risk by 75%. |
Quoting kaiarahi (Reply 45): If you actually look at the data, you'll see that the vast majority of accidents in Canada occur at bush/remote strips, of which we have many. Good luck cutting grooves into gravel or grass! |
Quoting kaiarahi (Reply 46): Quoting JBirdAV8r (Reply 42):they have found that having grooved runways reduces overrun risk by 75%.Who's "they"? That's certainly not what the joint TC/FAA/NASA/NCR studies found for climates like Ottawa's. |
Quoting JBirdAV8r (Reply 47): The report, verbatim: |
Quoting ac888yow (Reply 39): It is resting on the West side of and perpendicular to runway 32, at approximately the Kilo taxiway (around where 140.4 degrees is indicated on the chart). |
Quoting kaiarahi (Reply 45): Interestingly, they ended up facing away from the wind. |
Quoting okie (Reply 40): You can not tell if they landed long or were just simply carrying too much speed trying to get to a taxiway to exit runway. Could be a brake problem too many questions. |
Quoting kaiarahi (Reply 45): There are no taxiways on the west side of 14/32 - so unless they were trying to do a doughnut |
