FWIW local news sources all saying 1000 French time:
Oops, sorry - yes, takeoff due 1000CET/0900BST/0800UTC, webcast starts an hour beforehand.. :\

I did get it right in a post at lunchtime, but PPRuNe has been having database issues and a number of posts have disappeared from this and other threads.

FYI the whole 5+ hours video is still available at the aformentioned "live" link. Not live anymore, obviously, but still watchable (and quite enjoyable).
These Airbus PR people are good. The images from the companion plane are breathtaking. Quite a show I must say. Even the weather has cooperated :)
I'm eager to read some insider information here. The official stance is that everything has been "nominal" but I'm sure something must have gone a bit wrong somewhere, hasn't it?

What about all those probes & ports?
 
Since the question will come up some day, here is the answer in advance.

Probes ...
 
Which ones are for flight testing period, which ones are to stay ?

Tarq57 15th Jun 2013 01:11

Thanks for that, A33Zab.

Ugly nose.

Frex 15th Jun 2013 04:37


What's the saying? "If it looks right, it'll fly right". To me, that looks very "right" - bit like the 757-200 did/does.

Do we know cruise Mach yet - the sweep on the wings looks huge.
tribute to Marcel Dassault...

Speed is planned to match A380's one then M0.85. That's why the sweep is increased by 3° compared to the A330/340 to reach 35°.

Almost ready to fly over Paris Airshow now...

All mentioned probes and ports are standard equipment.

That makes it more crowded that the nose of the 380 then.

I go to a little visit of this aircraft. In X-tra category there is a 360° cockpit view :)

Sorry but there was an error 404 Not Found
Just as I thought! The first cockpit-less airliner! :ouch:

Hey!

MFPs look good to me. Aren't there (among many things, I'm sure) what some people (and I among others) discussed about 447, i.e. a simple & easy way to avoid NCDing AoA values because of a lack of forward airspeed? :cool:

A33Zab 17th Jun 2013 22:48

@AZR:

forward airspeed?
Was already available before AF447 = BUSS.
Optional on A320/A330/A340 (it requires a certain level of EIS1 or EIS2) and is standard equipment on A380/A350.

Still no joy. I cna get on to the A350 home page as you have written, but when I click on the Extra dropdown then 360° cockpit view, "Error 404". Musn't be available south of the equator! :{

According to Airbus, BUSS is not usable above FL250....

A33Zab 18th Jun 2013 08:20

The BUSS comes with AoA sensing thru IR (above the sensing thru ADR).
You don't have to activate the BUSS for this. its there once installed.


According to Airbus, BUSS is not usable above FL250....
It is still usable, but not advised, because if icing of pitots occurs above FL250 this is only a temporary situation.

Wasn't it because the BUSS green AoA range is valid for low altitudes only? (No Mach correction on stall AoA)

probes and BUSS

What is noticeable is the increase in the number of probes and ports and also how they have been regrouped and placed at the very front end ...


It is still usable, but not advised, because if icing of pitots occurs above FL250 this is only a temporary situation.
Also the judiciary experts have noted that :
  • Its utilization requests a lot of attention
  • Its utilization is uneasy when changing the configuration
  • Its activation is irreversible
  • Its utilization requests regular training
