Happened to an SSV A320 a few years ago at Cardiff. Crew spent precious moments recycling the Anti-skid switch but to no avail.
A/c finally stopped with wing tip hanging over end lights, and tyres burst due to use of parking brake!!

Yet another 'lucky' escape!!

Dont blame the crew (well not yet), against what could be another innapropriate QRH drill!! (Or a memory item, or pot luck............ )

At my Airline (DLH) we have a All-Memory-Action (some of the fes) QRH-Procedure 'Loss of Braking'.

Since the Brake-System of the A320 can and will obviously fail in various ways, this procedure and its handling can be very important and are trained in almost every Sim-Ride.

I'm wondering, if it's an operator's or a manufacturer's procedure - which other operators also have this one available? It gos like that:

LOSS OF BRAKING

- If autobrake is selected
Brake Pedals...............Press


- If no braking available
Reverser......................Max
Brake Pedals............Release
A/SKID&N/W STRG.........OFF
Brake Pedals...............Press
MAX BRK PRESS......1000 PSI


- If still no braking
Parking Brake................USE


Nevertheless I think that it should be possible to decelerate even an heavy A321 considerably on Naples 2400 Meters upsloaping (0,8%?) RWY.

However REVERSE has to come up right away after Touchdown. As we are just starting a campaign against ALAs (Approach and Landing Accidents) it might become procedural to select MAX REVERSE after ervery Landing and to reduce to Idle as soon as possible if everything looks well.


I was tought it this way from the beginning (see my Nick ) and there sure are scenarioes, where it could save the day.


Fly Safe, MAX reverse

Just talking about the 320 family braking discussion, question:

......MAX BRK PRESS......1000 PSI....

How about the LH A-319? YOU have to regulate up to 1000 PSI? Or is it system regulated as on ther newer A-319?

Max reverse may actually cover up a non-working brake system. Taking the scenario of Low autobrake, max reverse initially will provide all the decel and the light will illuminate. Only when reverse becomes less efficient will the non-working brakes become apparent. With idle reverse ineffective brakes will be noticed immediately.

Exclamation

Having flown the Airbus 320/321 for more than 11 years, total brake failure is not a new thing, sorry to say that !
Some years ago the "Brake dual shuttle valve" was blamed. A new was introduced.
Brake failures still occur, and brake failure procedures are a major subject on each OPC now = Antiskid/NWS SW OFF - alternate braking. Last resort = park brake ON
Interesting to hear what the problem was this time. My guess is that the crew will be blamed for not dealing with a faulty system in a proper way. Where actually Airbus is to be blamed for having designed a "bad" brake system.
Well I should not speculate about this, but wait for the report........

Well said, If a car had same problem, it would get fixed, why is this problem still not fixed.????????????

Older airframes: hydraulic controls for the brakes
Newer aircraft: electrical controls

We need to go deep into FCOM1 on this.

Signor Heavydog

Thanks for the comment. Suggest you study carefully Alitalia's safety record before commenting on this subject. Have a nice day.

Grazie Sodapop - I thought that comment was both inaccurate and unkind as well.

Latest incarnation of the 320 hydraulic and braking system has automatic limiting to 1000 psi when on alternate brakes. It also moved the nosewheel steering from Green system to Yellow.
