AC Flight 172 Diverted To YXU

Sat Sep 15, 2007 10:40 am

Air Canada A320 flight 172 from Edmonton to Toronto had diverted to London YXU just before 7pm tonight. Does anyone know why it diverted to YXU? Was weather the factor in Toronto or was something happened with A320? Any idea? I would like to know why.

Thank you!

According to our system, it was diverted due to "YYZ WXX" (weather). I tried looking for other diversions, but the only thing I came up with was a YQT-YYZ flight that was departed Thunder Bay a bitlate because of YYZ ground holds. The weather didn't seem to be a real problem tonight, but perhaps AC172 was put in a hold and had to divert for additional fuel?

Thanks RP TPA - Is there any link so I can see the info of this reg# of A320 at YXU if you see one later?

There was quite the wind storm and heavy rain in YYZ but didn't seem to have lightning involved at least downtown. It may have out by the airport. Could have been windshear or other warnings which stretch the flight spacing out and increase hold and circling times. Probably was a fuel issue.

there was lightning out by the airport last night, and very poor visibility right around 7pm (at least on Derry Rd and 410...)

The weather front that passed through was very particular. It wasn't uniform throughout the region. In my area, we had a good 90 minutes of heavy winds and rain. The temperature, which peaked in mid-afternoon at 28 degrees, had fallen to 14 degrees by early evening.

Thanks! I have checked with airport staff why AC A320 C-FDQQ was here at YXU last night. I was told that it was the weather at YYZ and the A320 landed here to have re-fuelled and waited for an hour before head to YYZ.

Last June similiar situation happened here at YXU where AC A320 from Vancouver diverted to London as well.

Thanks to you all guys!

The strong northwest winds dictated a 33L/33R operation. When this happens there are usually holds involved. AC172/14 did not have the required fuel for the given estimated hold and diverted to its alternate. Once on the ground, it was "ground held" until airborne aircraft could arrive into YYZ, as they always have priority.

Is London the most common alternate for YYZ? If not, what is?

EDIT: Just thought of Hamilton. Would that be the normal alternate?

There was definitely some weather problem at YYZ on Friday. I was coming home on AC 421 from YUL, we were holding above the lake for approximately 30 min, then we landed at 33R. My flight to YXU was late too, the aircraft arrived around 19.00 (scheduled dep. 19.10). We departed approximately at 19.30.

Quoting Boeing744 (Reply 8):

Alternates vary from one airline policy to another. However, alternates for YYZ can be summarized as follows:

1) YHM
2) YXU
3) YOW
4) YWG - seems quite far away but the DX system lists it as an alternate.

YKF runway is too short (7000') and only has CAT I capabilities thus it is not suitable for aircraft larger than a B767.

Actually you missed one:

YYB, North Bay, 10000', Cat 2 ILS.

Air Canada lists YYB as its alternate on alot of flights.

We also hold BUF, IAG and YTR on occasion for YYZ alternates.

YWG? Wow, that's over 800nm away! I'm guessing it's for international flights coming to YYZ and there's a huge storm over southern Ontario?

Yes I thought that it was quite far away as well. Remember that the information I provided was based on the DX system I use and not company specific to AC.

I expect YWG would primarily be used as an alternate for transpacific flights from NRT/HKG/PEK/PVG to YYZ when the YYZ/YOW/YUL area may sometimes be affected by the same kind of weather.
