787 bounce

Is that a boing 787?

Jet Jockey A4 9th Feb 2019 12:28

You mean this one...

Assuming the invisible link is a reference to the BA B788 at LHR yesterday, try Spectators Balcony here:

It looked like a well handled go around and was appropriate given the conditions.

jurassicjockey 9th Feb 2019 12:59

Looks like full elevator input as the nose dropped. That was some ugly shear.

Yes I noticed that too in the picture from the BBC link... Personally I think they did a great job recuperating from the event and the go-around was the right decision.

Capn Bloggs 9th Feb 2019 13:34

That looks a bit crazy. Why would windshear suddenly pitch the nose down so abruptly? Fair enough the @rse drops out of it if you lose speed, but that was a violent pitch down. That was not the secondary effect of controls lowering the nose because the speed has reduced. Something fishy somewhere. Reminds me a bit of that Prune 787 (IIRC) video of weird nose down pitches on short final. Brother of MACS??

Reminds me of flying into St. John's on a nice day

True but there was a large down elevator input just before the nose pitched down.

The Ancient Geek 9th Feb 2019 14:46

Looks to me like he should have gone around rather earlier rather than try to save an approach that had clearly gone wrong.
But he was there and I was not so what do I know.........

No one ever does. Very clever on the part of the OP. :O

Clearly, they should have should have tootled around the coast a bit before diverting to MAN. :}

Looked quite the opposite to me! It only went "wrong" in the last seconds and they immediately took the correct action which was well executed.

I think that you're looking at the flaperons. The elevator is visually blocked by the wing except for when it goes up. There is a large amount of flaperon movement just before the * hits the wall

Locked door 9th Feb 2019 15:16

As per the previous poster, the elevator is completely obscured until the pitch up input. It looks like a really nasty shear late on with an excellent catch and well flown windshear go around, hence the gear staying down.

Nice job, stay safe out there.

Akrapovic 9th Feb 2019 16:56

Reminds me of an incident easyJet had with an Airbus going in to Luton. FO under training for the left hand seat had a brain melt and stuffed the nose forward at low level. Not saying this is the case, but can’t be ruled out....

wiggy 9th Feb 2019 17:02

Jeepers....I thought the NFL season finished last weekend and in any event it isn’t Monday for a couple of days.....

:oh:

Global Aviator 9th Feb 2019 17:20

Approach in gusty conditions, wind does weird things!

****e got real very low level...

Go around, perfectly executed!

BluSdUp 9th Feb 2019 17:31

Windshear?
Or gust? Big difference!
Does anyone have the Metar and the Tower wind when cleared to land. And any " wind check"?

Nice to have the AAIB on board, especially with such insight. But did you consider the possibility that all the passengers, seeing the problems the crew were having with gusts, decided to rush forward and advise them how to handle it? Not saying this is the case, but can’t be ruled out....

Where is the like button!!!

student88 9th Feb 2019 19:50

Excellent job by the professionals sat at the front :ok:

Well done to the crew.

srjumbo747 9th Feb 2019 20:02

Perfectly flown. Last minute windshear and gone around hence the reason to leave the gear down until above MSA.

ILS27LEFT 9th Feb 2019 20:49

Perfectly executed
 
Perfectly executed. Horrible ground level gusts at the time of this go around, excellent job done indeed. No reason to go around any earlier, all incoming flights were having very bumpy approaches at LHR most of yesterday and it would have meant all flights going around based on footage. GA started when appropriate and actually very very quickly considering the very sudden wind gust at basically ground level vs reaction time of pilot & then GA delay on aircraft.

Really? You’re confusing windshear with gpws. Back to flight sim.

Suvarnabhumi 9th Feb 2019 21:01

Anyone know if the aircraft has flown again yet ? Or the max g load on touchdown?

Was it 27R and wind from the south ?

Actually, the windshear escape manouvre calls for no configuration changes.

/bangs head against brick wall/

Correct, but MSA is irrelevant for windshear escape but very relevant for gpws escape.

I really wonder how many genuine commercial pilots there are on this forum.

ManaAdaSystem 9th Feb 2019 21:12

The windshear escape manouvre does not consider terrain, it deals with windshear only.
You make me wonder.

FlightDetent 9th Feb 2019 21:43

M.A.S, he was picking on the MSA bit of the previous post, not the no-change of configuration. You are both on the same page.

I was already banging my head on the wall after the first one. Glad to see I've got some company! :ugh:

OntimeexceptACARS 9th Feb 2019 22:35

When do you think they pressed TOGA? Before first touchdown? Looked an impressive climb out, no doubt helped by the windspeed. Asking as SLF...

You could well be right as I didn't know they had flaperons.

Gipsy Queen 9th Feb 2019 23:27

As has been noted, it is difficult to see because the view is obscured by the wing, but it's almost as if the up-elevator anticipated the shear/gust. Commendably quick response on the part of the PF.

Loose rivets 10th Feb 2019 01:40

Without making comment about this particular go-around, is it mandatory to buzz off, or can one legally push it back on?

I gather it had a hard landing check (as did a handful of other aircraft at LHR that day) and I believe flew again with little if any change to it’s next planned rotation.

Capn Bloggs 10th Feb 2019 03:32

You could try, but this might be the result...

A tad dramatic perhaps but maybe. It depends. Maybe. In this case, probably not.

Bravohotel 10th Feb 2019 06:38

Have you seen the second approach, almost did the same thing but did not go-around and landed ok.I have replayed both arrivals many times and its strange that a lot of the other arrivals around that time before & after seemed ok considering the condition.
