Swing over with missed approach
 

Let's assume you are flying an ILS at airport with two parallel runways e.g. 27L. You are offered a swing over to 27R and you do so. For any reason a missed approach has to be conducted. Which procedure do you fly, for 27L or 27R ?

I'll go out on a limb here and say follow ATC instructions. :E

Without any contrary instructions from ATC, follow the missed approach of the runway you are landing on i.e. 27R.

A lot of missed approach procedures are designed to separate a/c using a parallel runway usually by turning away. So 27R would have a turn to the right and 27L a turn to the left.

It's not a situation that I have to handle as a controller at present....and I don't have the books to hand to check....but I have always thought it was the missed approach associated with the instrument approach that you followed (before any visual manoeuvring) that should be flown.

But, as ever, if you're not sure and there are no instructions forthcoming from ATC - ask.

I'd say that if you're flying the instrument approach to 27L and get offered a switch of 27R by the means of a visual manoevre then you're now flying a visual approach to 27R. So by definition if you execute a missed approach/ go around then i'd fly the published procedure for 27R.

In the USA, you would now be "visual". So you would carry out a visual go-around not the IFR go-around.

So for a swing, I am told it would be straight ahead to circuit height and ask ATC asap.

I think.

Fly the go-around for the runway you are landing on! For all you know, you may have been swung over to the other runway so a departure can take place on the runway you were approaching on. So if you do the original go-around, you would be turning over the departing aeroplane. It would be common sense to advise you were 'turning right on the go-around'.

I for one shall stick my neck out and say if you have been cleared for an instrument procedure on 27L and then lose the runway whilst trying to circle for 27R, then my 0.02p's worth is that you fly the missed approach procedure for the runway that you initially shot the approach on.

People above have mentioned parallel runways, thats a bit of a red herring.

Luckily circling is not something we do often. But consider 27ILS at Memphis circle for the 18's and perhaps a bit more nearer home 27ILS and circle R22 at Amsterjam, doing the 22 go around would cause chaos!

Now between the 0 degree difference in runway heading in the case of a parallel runway and the 90degree difference at Memphis is there a certain difference of alignment that we should change procedure?

When ATC clear you for the swing over ask them what they would like you to do in the event of a missed approach. Problem solved....

Assuming you can get a word in - which is why you might be going around in the first place.....

Is it now a circle to land? If so then the miss should be that for the instrument approach just conducted.

L337- we don't have such things as visual go-arounds in Europe- it's a US thing.

GSPOT- you're changing the question to suit your answer. The question was about 2 parallel runways as at LHR. You have no experience at airline ops at airports like LHR, so your answer is misleading.

I have had this situation at LHR several times over the years. Each time there has been the opportunity to switch over ILS to the new runway. So why would you fly a go-around on a runway you are no longer approaching? As I said, the likely reasons are: slow clearer ahead and other runway clear, opportunity to take off aeroplane on original runway and other runway clear, or other runway clear and you want to park near that side anyway. So if another aeroplane then gets cleared to go on your original runway, and then you decide to go around and turn across LHR and overfly your original runway that another aeroplane may be lifting off, then you are demented and need to be carted off. You have simply changed your approach to a different runway! Why on earth would you then fly a go around for a different runway? It's crazy! It is not a circling approach! Why try and make it one? This is the real world, not academic ATPL stuff, and an element of common sense is needed.

I do not believe ATC do this any more at LHR anyway. It is a procedure that is now frowned upon in airline ops I believe. It must make the flight recorder monitoring go crazy.

So Rainboe,

what about EDDF 25L swing to 25R or
LSZH approach to 14 swing to 16.....???

I repeat- we are not talking circling approaches! ATC have switched you to another runway. They will then expect you to follow procedures for that runway. If following the original runway's GA leads to a hazard (as at LHR) then you will cause considerable surprise in the tower following a procedure that is not expected by ATC. It is 10 years since I have habitually visited FRA and ZRH, I am not that familiar with them anymore.

Does the logic some of you are using mean that if at 3000' I am switched over to another runway, then I should fly the original GA? Extraordinary!

Concerning EDDF, ATC expects you to follow M/A for 25L even you have swung to 25R.....

LSZH, I have no idea:ugh:

Why? Isn't there a note to this effect on the landing plate- I seem to recall one? Does that make it a requirement everywhere or does that make it a special exceptional requirement for FRA 25L/R?

To my limited knowledge it's amongst whole germany. Got that from a german atco.

A good gotcha is accepting a swing acrooss to the parallel runway when visual and forgetting the missed approach for the original runway remains in the FMS. Seen this happen a few times at KJFK when originally cleared 13L then offered 13R which is quite a bit closer off the non precision approach. Aircraft gets high or unstable, goes round and the pilot re-engages the NAV mode and all hell brakes lose. Swingovers were a lot easier in early generation jets than the 340's and 777's where someone needs to put a head down to update an FMS when all eyes should be outside the cockpit. Personally I don't accept them anymore, unless briefed and then I fly the G/A if reqired in a basic mode or ask ATC to maintain runway heading.

I thought a circling approach was defined as a 30deg or more change from the FAT to the runway... So most of those we are discussing are technically "switches" rather than circling?

I think I would do the the G/A applicable to the runway I was trying to land on, unless otherwise advised by ATC or notes on the plate.

At Heathrow, if you are on the ILS 27R, and we switch you visually to 27L, we will expect you to carry out the 27R missed approach procedure (i.e. the one you briefed, and the one you set up for).

Thus, you can be sure we will give you positive missed approach instructions ASAP.
