Go-around In COS

Thu Oct 05, 2006 7:33 am

Yesterday I flew on UA426 from DEN-COS. Aircraft was an A-319. We departed late after our aircraft came in from somewhere (not Jackson Hole as was scheduled since that leg was cancelled); we took off at about 4:40 p.m. The flight was quite bumpy due to thunderstorms and our low altitude (only about 10,000 feet, which is typical for this short flght).

As we descended at about 4:55 p.m. I noticed the very unsettled sky and lots of bumps but nothing too weird. At about 1,500 feet (approaching 35L I presume) the engines went to full power but the sensation was weird, like we weren't really speeding up or climbing for about 10 seconds. Then we pulled up sharply to the left and climbed a few thousand feet.

The captain came on and informed us that "the wind shifted around to behind us so we'll go around and land into the wind from the other direction." Out the window was lots of blowing dust, rain and wind. We came in from the south and landed on 17R.

Was this the wind shifting, wind shear or a combination of both? I've had go-arounds but they were due to other aircraft on the runway, not weather.

So my last mainline UA flight DEN-COS (Oct. 30 is the last day of mainline service at COS) was memorable! This was sort of scary, but unusual and a tiny bit fun.

Well, the wind probably shifted, and the pilot was being straight up with you. Landing with a tail wind is a bad thing, ask the WN crew who went off the end of the runway at MDW last December...

There probably was a little shear involved. There always is when flying near mountains, especially the front range of the Rockies Big grin

It doesn't surprise me that you had to go around. The wind here does crazy things because of the Mountains. All flight opps at the Academy Air Field were canceled yesterday afternoon of the same weather that you were talking about.
Why fly with 2 engines when you can have 3?

I figured it was a minor thing but I couldn't help thinking "UA585" and the crash at Widefield near COS back in 1992. Of course it was the rudder problem on the 737 but windshear was a factor, no?

I don't think that windshear was a problem. It had the same rudder problem that the USAir flight did two years later. Weather could have played a small factor thought. I can't remember a time when I've ever had a smooth landing in COS.

Came in from the south and made a tight pattern to land to the south?

Oops - got it backwards. We came in intially to the south, so it would have been 17R. Then we turned around and landed to the north, on 35L. Sorry - I'm not a pilot!

Same thing happened to me when I was flying MSP-HDN. There was a snowstorm in HDN and the visibility was extremely low. I think however the go-around was due to the visibility since the runway is not equipped with ILS. It was quite scary though when you know the weather is bad, visibility bad, bumpy ride and suddenly right before touchdown you hear a big roar and you're climbing again. Quite neat though nonetheless.

COS is consistently bumpy, true. I live in DEN and it's bumpy there, too, but not like COS. But COS is much closer to the mountains than DEN, so that's a factor. Spring and fall can be very unsettled - UA585 actually was March 3, 1991. My mistake.

But I have to say that I'm always impressed by the skill and professionalism of UA flight crews. They're the best.
