Airbus technology defects

There are no brakes on the nosegear of the A319 (or on any other aircraft that I am aware of).

Try the 727!

Heineken Ad:

Just after the captain says "This is the captain speaking ..." the front of the plane dips down and the nose wheels smoke (as if being locked up by the brakes), something that would be pretty hard given J.O.'s reply...

Sorry WAGM (I truly am not having a shot at you mate) I can't see that video as being real, unless someone has more info not yet shared.

Cheers,

This is what you may be looking for:

Bulletin 812 for 320/1

To paraphrase: If you are in heavy rain the radalts can sense an incorrect height.

If both radalts are affected at once:

If the value detected is greater than 150' spurious autocall out and spurious ECAMs or GPWS warnings.

If value between 150' and 80'

During auto approach:
degradation of the guidance, glideslope no longer flown, excessive deviations can occur.
Variation of londitudinal pitch and or vertical speed leading to GPWS warning.
During Manual approach:
No adverse warnings but GPWS or autocall out warning may be triggered.

Had it once in very heavy rain on descent. Numerous ECAMs and a flash of GPWS.

In all honesty, the quality of the beer advert video reminds me a lot of flight sim....

I would perhaps cautiously offer this as the possible source of the "false" video...

Forget the ad please

Moving on from the ad debate thanks.

Has anyone else with airbus experience had problems with the Radalt system and/or informed thoughts on it's effect on flight laws/air ground logic etc

Non pilot speaking: If I read some of these posts correctly, some people think that the Heineken advert shows a real video of a real a/c??? Shurely shome mistake. Anyone can see that it's been frigged in the video suite.

[flown-it]

Back to the original thread.
Doesn't matter if it be 'bus or boeing. The Mode control panel or what ever the manufacturer choses to call it is The Fiction Panel. If you don't know what your mode annunciators say then you can bet the aircraft will be flying you!! FPA 3.3 or V/S 3300 would have been a non event if they'd only checked the FMAs after making the selection.

It is possible that you will find some 727's with nosegear-brakes fitted.
I've got 1000's of hours on the 727 and none of them had brakes up front.

Clearly fake, not even a Bus can do that.

Can you prove your accusation?

Therefore, as you seem to follow this file in France, I have a few questions to ask you and it seems more important to take an interest on this.

First question. In what he reports, Norbert Jacquet refers to false licenses pilot:

One can also add the false airline pilot licenses. Incredible. On two occasions, the authorities gave a false airline pilot license to Asseline, who was flying the crashed Airbus in Habsheim. The facsimiles of these fakes were published, with the signatures and the names of the forgers (press). It is ludicrous. I transmitted these, with some comments, to judge Guichard, who was in charge of the two investigations on the two air disasters, still in progress at this time, to the public prosecutor's office in Colmar (in Alsace), to the public prosecutor's office in Paris, and also in higher place. General silence was the answer. The forgers are well protected. I was even locked up in jail, to preserve their protection!

This story of these false licenses is really unbelievable. What do you think about it? Is France a banana republic? Could a banana republic build aircrafts worthy of the name?

If you do find one (most likely a 100 series) and are planning a max brake landing I recommend using the locking lever on the shoulder harness!

The 200's delivered to Australia had them. I can't recall whether the 100's did. Time was mainly on 200 but initial type was 100, many moons ago.

From memory they activated after about 2/3 pedal travel, so did not factor in normal ops.

Tree, I had thousands of hours on the Convair 880M which had nosewheel brakes fed by No.1 Hydraulic system. (Definitely showing my age. )

1. The a/c can be flwon like any others
2. Fly,navigate,comunicate
3.One head up all times
4.Cross check the accuracy of the FMS
5. KNOW YOUR FMA ALL TIMES
6.WHEN THINGS DON'T GO AS EXPEXTED TAKE OVER
7.Use proper level of automaton for the task
8.PRACTICE TASK SHARING AND BACK UP EACH OTHERS.

Errors are human and we all do them, we shouldn't blame the A/C if we don't know its systems..

I don't think the Airbus is perfect but I am sure it doesn't have any more defects than others...

All the modern fighters are fly by wire (some fly by light)..
Get used to it...

I certainly do agree that in that kind of automated airplanes, the AIR/GND logic can play many tricks, and engineers or certification process can not imagine or produce all that before airline pilots will have to experiment by themselves ...

It is quite common these days to get an "LDG MEMO" at FL370 over the NAT tracks associated to a RAD ALT showing 1000... just because you're not the only one out there...

Regarding your link, they don't talk about pilots experience and background, and as a RA FAULT implies using MANUAL PITCH TRIM, they may well have forgotten how to use that after flying the bus for too long ... witch could explain the too many bounces!?

What can I say... you probably report the commonly accepted official version, but did you go further... ?

Have you ever seen at Farnborough one of these Airbuses demonstrating its capabilities of very slow flying... did you notice the resulting attitude?
Now, do you believe that Habsheim 320 was showing that typical attitude... or there were still many nose up degrees to extract before staling!?

Do you know that no more than 3 days after the crash, all the trees on the airplane path have been cut, before producing any clues?

Do you know that flight recorders have been hidden from Justice during the first... 10 days?

Do you know that brand new 320 technology was allowed only 1200 hours certification ... when Airbus decided to implement a 2000 hours program for the later 340?

Reading out of the box can teach all of us many things...

[stilton]

All our 727's in our Micronesian operation had working nose gear brakes at one time (-100's and -200's)

They worked very well.

[Ignition Override]

To 'second' somebody's 'motion' up there, when something does not look, sound or feel right, take over.
The computers might be flying most of the time-but they can not override your authority.


Easy for me to say- how to take over will be the problem.

My first Airbus ground school begins in 4 weeks, however the company produced what appears to be an excellent CD-ROM to study in advance. So far the info seems to be structured in a very clear, logical manner.

[Speevy]

you want to take over:
simple revert to Speed Heading V/S or any other selected modes (op clb,etc) if that doesn't help there is a red push button you usually use to disconect the automatics isn't?

For CONF iture: The accident you refering to, I don't knw all those details, but did you know that the captain was trying to show how smart was the a/c demostrating Alpha Floor but forgot this:
ALPHA-FLOOR PROTECTION
Alpha-floor protection automatically sets the thrust at TOGA thrust, when the aircraft reaches a very high angle of attack.
The Flight Augmentation Computer (FAC) generates the signal that triggers the alpha-floor mode. This, in turn, sets TOGA thrust on the engines, regardless of the thrust lever positions.
The FAC sends this signal when the angle of attack is above a predetermined threshold, that is a function of the configuration.
In CONF3 and CONF FULL, this threshold decreases as a function of the aircraft deceleration rate (down to - 3°).
Alpha-floor is available from lift-off until the aircraft reaches 100 feet RA in approach.

I repeat, errors tend to be uman in any case...

If you comand Toga the A320 will go around!!! Look at the Tap video (the one about the xwind) they applyed Toga almost when they were already on th GND if there is any delay is caused by the Spool up time common to all A/C (the 737 and the A320 got almost the same CFM)...

If I am flyng the a/C and something doesn't look right I would take over no matter which a/c we're talking about..

Sorry:
What's the difference between an A-320 and a chainsaw?
About a hundred trees a minute...
