Thomson A/C In flight shutdown

[picu]

I think we can forgive the 7700 squark (sic), the rest looked spot on,

Was it really necessary to set the transponder to 7700? I would think that since the aircraft already has an assigned xponder code, there is no harm in leaving that on. Perhaps any ATC folks could help clarify on this?

Well done to all involved.

From the Emergency section in the Jepps manual.

2.4.1 The pilot of an aircraft encountering a
state of emergency shall set the transponder to
Mode A Code 7700 except when previously directed
by ATC to operate the transponder on a specified
code. In the latter case he shall maintain the specified
code unless otherwise advised by ATC. (Doc
8168, Vol I, Part VIII, 1.4.1)

[Julian Hensey]

Transponder on 7700 allows all ATCO's working the area to see the aircraft instantly on whatever radar they are working. Remember that ATCO's that are not directly involved but working the airspace above or to the sides of the area will be able to ensure traffic is routed around or away from any direction the mayday aircraft is going or may need to go. It instantly flags up the problem aircraft on the screen even if they weren't aware of the problem straight away.

Or so I have been told....

Thanks Amex/Julian

Regarding the Jepp quote, I wonder if the xponder code given in the initial airways clearance (by delivery) is the same as

except when previously directed
by ATC to operate the transponder on a specified
code.

I can also see Julian's point, which makes sense.

Not meaning to criticize at all here. Just trying to learn from it. This dilemma crops up every now and then in training.

I would tend to keep my assigned code, unless I was on a 7000 or no code at all. In that case I would revert to the appropriate emergency code.

Probably more a point relevant to the ATC forum so before I go, congrats to the Whitehatters involved as well as all other units involved.

Protected
Arent Herons protected, those boys could be in trouble with the authorities
Well done though chaps...

very funny rolling20, again very well done to the crew especially the pilots, good to see they kept calm!! cnt see it being too relaxing however!!

[rampman]

just to clear a little thing up it was not a Heron but two crows that were chasing the heron and before anyone ask me how do i know i was talking to a friend who works for airfield ops .
i must say the pilot and atco are two cool cookies in my book well done all

Fark me! It's a flippin Safari park..

When selecting 7700 in an emergency, as well as alerting the controllers working adjacent airspace, it immediately alerts D&D too. I would always use it in an emergency of this nature.

[chiglet]

AFAIK, it's also SOP for ATC to inform D&D too
watp,iktch

[picu]

pardon my ignorance - what does D&D stand for?

[llondel]

Based on the soundtrack to the video, I'm pretty sure I heard ATC ask them to squawk 7700, just after they switched frequency. That's a good enough reason to use it, I'd say.

[ScottyDoo]

I think if the aircraft had being a 737-200, I don't think the pratt-whitney would have taken that strain like our 757 BYAW did?

Why not, are the 737s with PWs certified to a lower standard than everything else?

What does it have to do with the type of airframe or the rego, was BYAW a lucky machine?

Why are engines not fitted with engine grills?

A bit silly. But they should definitely look into fitting a big triangular thing on the front of the engines like the old steam engines had for pushing cows out of the way in front of them. A big steel thing. That way the bird wouldn't be hurt.

Or fly slower during the take off so the birds hear it coming. This should be standard.

I'd have been puckering up the seat cushion if it were me up there, flying around wondering if we'd hoovered up a few more chooks into the good donk too...

Outside Broadcast Journalistic Quote of the Year:

".......Two Herons (Large Wading Birds) "

W**k Bingo, anyone?

"Thanks Jeremy, and now back to the Studio (Small box-sized room with Presenter and blue background in London)."

Bingo!

PM truly ahead of the game, already thinking about routing to WAL. Am not worthy.

[MightyGem]

pardon my ignorance - what does D&D stand for

Distress and Diversion. They monitor the emergency frequencies down at West Drayton(unless they've moved in the last few years).

[Woof etc]

One wonders how they determined it was a pair of herons that caused the fun. Looks like they were well and truly toasted.

[Ceannairceach]

Yup, SOPs apart and from an ATC point of view Liverpool, Warton and Hawarden amongst others all have bits of airspace that the aircraft could have come close to.

Best to let everyone know that someone's in trouble so they can keep their stuff nice and out of the way. Basically.

[blue up]

If enought bits go through the outer section of the Fan then they won't have gone through the burner. Only the inner 2/3 of the air will go down the hot section and the rest bypasses the burner (hence the name high bypass engine) This outer air is moderately cool so they can recover a single feather and identify the bird from that.
I had a strike at EMA one christmas morning. The fire service said it was a Golden Plover but ATC said they thought it was a Turkey.

[Mr @ Spotty M]

Rolls Royce have sent bird remains for DNA testing.

Finally! At last there is someone thinking about the poor birds.
