The Heathrow Shimmy
Friday night SLF inbound for 09L from a little Isle to the west, and vectors from the Bovingdon hold, appeared to overstep the 09L localiser abeam Woodley, got it back together, then invited to shimmy onto 09R quite late over Queen Mary's.
Did'nt worry me since I knew what was happening, however a few souls gasped
when the starboard wing dropped quickly towards the pond.
Question: How late would you attempt the shimmy, before you go TOGA

It's always a notable thing to see from the ground as well, saw a 27R to 27L sideslip a week or two ago. Presumably caused by the spacing getting too tight. Wonder how many departure slots get suddenly lost by such action, two or three ?
And it's something that maybe will not be possible with mixed mode. Will a go-around will be the only option then.

The Trident was great at this manoeuvre. I once watched a Trident 3 hack across the maintenance area at an angle of about 45 degrees.

Used to be a standard thing at ZRH, with the added complication(s) that:
The RWs did not have thresholds at the same distance and
They were not parallel.
The main reason to sidestep (they called it swingover) was to get a clear run to the parking area and save about 5min taxy time.
Whether you did it or not (provided it was offered) depended to a large extent on not only the vis. but the direction of the sun. There was quite often haze out to the north too, which the tower couldn´t see.
Anyway all those fun and games stopped when someone got a bit too cavalier and pranged a wing on touch down. Shame really.
How to do it:
Be established on speed and config. early
Have it well briefed beforehand (GA might be different etc.)
Be ready for a last minute change (ATC has a few other things going on)
Do it Visually, and be ready visually before the sidestep is made! Don't try to follow at the last minute GP and Loc on some instrument.
Get on the Centreline first and assess Glide after that.
Enjoy!

Life's too short to brief for a runway swap on every approach into LHR! It's essentially a visual manoeuvre only which I've done several times. So:
Autopilot/Flight Directors off
turn straight away, don't overshoot centreline
get on VASIs as soon as possible- forget retuning ILS
get new go-around read to you- if time get new runway in FMS, but not essential
it will be a manual go-around, just like the old days!

Like several here I have had it 'offered' several times in my life and I agree it is worth including in the brief for those places where it is 'likely'. I fear that bringing a new F/O 'with me' on a late unbriefed runway swap is just asking too much of a one-man-band-show! As for 'getting it into the FMS....................'

Hi Rainboe.
Thanks for your top tips on side stepping late in the approach. Next time things get a bit tight I will shout "watch this" and time permitting put my boots and spurs on!

Below the Glidepath - not correcting
It seems to be a regular occurence at KMCO, where the difference between 17R and 17L is a significant taxi distance. All triggered by how fast the other guy vacates, so definitely an opportunity basis rather than a plan. Mind you, predominately blue sky helps a lot I suppose.

On a lighter note. The first time I ever came across this was late on in approach somewhere in Germany. To get the full effect you must say this in a very strong German accent.
"Ah British do you swing ?"
Caused amusement at the time.

Most impressive one I saw was a US Airways 737 coming into Washington National a few years ago, finals to a late vacating aicraft on Rwy 1, switched at about 500' to Rwy 33, all done over the river so no encroachment over DC (this was pre-9/11), but was still getting the bank off over the keys. Must have been ex-Navy driver.

Do you Swing?
Cheeky Visual - the right name for the post!
The best exponent of this manoever was a lady pilot called Katherin Fisch, which was probably the origin - not of the swing - but the song: "I wish I could shimmy like my sister Kate".

BOAC,

I assume you meant that tongue in cheek- ish?
Having come from a world of large multi-engine jets, but little of the fancy gadgetry of a modern airliner, I now tend to find there is an infernal preoccupation with that blasted FMS, at what I consider the most inoppurtune moments. In a sidestep manouevre of the nature discussed here you should be visual with both runways - sod the FMS (
), look out the window and land the bloody thing visually! Thats what the windows are for. Just because the runway doesn't appear on the ND or the magenta string doesn't go to my landing concrete does not mean we will disappear in to the Bermuda Triangle!
