I made an exchange year in Vancouver and since I love planes, I visited the airport nearly every weekend.
When sitting around, watching the planes come and go I saw something strange, a CX 747 was on final for the runway (I do not know which one) and like one minute before touchdown, the plane banked to the right and established for a landing on the parallel runway. I thought there might have been a problem with the original runway and that this would not be a normal procedure but during the following month I saw it many times again.
I am curious since I never saw this before (maybe because I do not live near an airport with a parallel runway system) but any info is appreciated.

Not sure how you definern"last second". There are some airports where pilot approach a runwayrnand then do a sidestep to another runway. This doesn't really happen inrnthe last second but lets say 30s or a minute before touch down. In ZRH eg. flights approached RWY16 and then turned into RWY14 iso. This has been done a few times earlier but not anymore.
In case of an emergency or when there is a problem with the approached runway, the would in most cases, if not in all, do a go-around.

At SLC I was getting ready to take off on 16L and a front passed and the wind changed direction, so hence the DL 752 had to make the long two mile taxi down to the other end to runway 34R. It added 20 minutes to the 4 hours of flight time to ATL.

You bring up a very interesting topic.
One week ago, I was on board an AA 737-800 from YYZ on final for LAX, approaching (westbound) the south end of the airport. There are two runways that are parallel on the south side: 7R/25L and 7L/25R. About 30 sec before touch down, there was a wide bank right and then left, and to me it seemed like we switched from 7R/25L to 7L/25R at "the last second".
I know that at LAX the 7R/25L and 7L/25R runway arrangement has been subject to some debate, and there are plans to relocate the runway 55 feet south, to improve safety, and to finalize preparations for the A380. http://www.lawa.org/news/newsDisplay.cfm?newsID=774
We're your kind of airline. Uh, I mean, We *were* your kind of airline.

Actually, moving LAX 7R/25L 55' south is not because of the A-380. The FAA has been concerned about the south side runway spacing at LAX for about 30 years now. Parellel runways in the US require 1200' spacing (centerline to centerline) between the runways. LAX has 1145' spacing on the south runway complex, so the "relocating" is really required. LAX was allowed to keep the present arrangement, with a wavier from the FAA, until it was time to replace the runway. That is what they are really doing, they are replaceing it with a new runway, that will be properly aligned.

To me it sounds like a side-step approach clearance. I remember at APA a while back, runway 35R was out of service and Denver Approach was clearing the aircraft for the ILS 35R, side-step 35L. Which means you fly the ILS and then switch to the other runway and land on it. I don't have time now, but check NOTAMS for the airport.

yes, such a maneuver is everything but uncommon. once happened to me while i had the chance to stay with the flight deck crew (when that was still permissible). beautiful approach into NCE (approaching NCE is a treat)), switching the runways like 30 sec or so before touchdown, awesome!
If only pure sweetness was offered, why's this bitter taste left in my mouth.

Quoting Carpethead (Reply 9): SFO is notorious for switching between 28R to 28L. No need to cross 28L then. Often times it's the UA pilots that request this because obviously they are the most familiar.
Very common at SFO as the runways are quite close together so it is easy to do. The inboard runway (28L) is usually used for depatures but if there is nobody departing the pilot might request to switch. This has happened to me many times there as well as from time to time in PHX and LAX.
If I'm not mistaken, if it is "last minute" the request will only be granted if the pilot is flying a visual approach.

This happened to me on a NW DC-9 on approach to MDW. Just before landing we banked hard to the right, flew by the airport, then banked hard left to line up with a runway (no parellel runways at MDW) just before landing. It scared the sh_t out of me. I asked the pilot about it and he said another plane had been accidentally cleared to take off on the same runway right before he landed, he didn't seem happy about it. I don't know how low we were, but it was so low you could read the billboards on the ground.

Quoting Timz (Reply 8): Wonder how close you can be and still do
I am looking all over the 7110.65, but so far, I cannot find anything that tells me the procedures. However, after a little internet search, I found this.
A. Visual maneuver at the completion of an instrument approach which allows straight-in landing minimums on a parallel runway not more than 1200 feet to either side of the approach runway.
B. Pilot should execute sidestep maneuver as soon as possible after the runway or runway environment is in sight.

I see this happen once every few times I'm up at SLC, something will be coming in for 34L and it'll suddenly hop onto 34R's approach path - usually no more than a minute out, sometimes less. It is very cool to see a plane bug out and head for a different approach so close in. My guess would be either FOD or someone taking too long to get off the runway (in effect, also FOD )

in my 3 years stationed at EDDF in the Air Force, I witnessed probably 10 or so total "side-steps." some would happen indeed very close to the runways, no more htan 60 seconds from touchdown, others might happen a bit further out. but it was quite exhilerating watching a 747 do a sidestep 60 seconds from touchdown.

Aircraft do sidestep to the other runway fairly often at YVR. At YVR the north runway is usually used for arrivals, and the South runway for departures. So my guess would be that they line the aircraft up for the north runway (26R), and then if there is a break in departures on the south runway (26L), then they can sidestep the aircraft over so that they have a shorter taxi distance.

Quoting Eham (Reply 19): It's a quite common procedure @ Amsterdam Schiphol, where (mostly) smaller airplanes brake off to rwy 24 for landing when following the ILS for rwy 27.
Or offcourse the better work, the cargo planes for both Martinair and KLM cargo ramps.
You can normally tell from the hight they approach rwy 27. Planes that do the brakeoff, are comming in a little higher then a normal ILS rwy 27 approach.

I was listening to UA ch. 9 on an evening approach to LAX and a couple of minutes before landing, the pilot requested switching to the (departure) right runway. It sounded like this was because we were in a heavy and it would allow the other UA planes behind us to land sooner.
