A320 wiper kept running
Wow, some really funny crap being written.
Firstly modern Airbus types ( the A330 and I'm sure the A320 is the same ) don't have circuit breakers in the cockpit, they are computer reset push buttons on the overhead panel.
Secondly, the CB for the wipers is located in the Equipment bay under the floor. I wouldn't suggest a Pilot go sniffing around down there in flight trying to find the correct one!!
besides there is no drop down Oxy down there and you'd need to take a portable bottle to be sure.....
In my opinion a good decision to return and get it turned off before scratching the window or overheating the motor or driving the Captain mad with the noise!! .....
( not to mention the 230 kt limit as well )

Airbus does not say to forget using common sense and airmanship. And the circuit breakers are not in the avionics bay: they're right behind the FO's seat on panel 122VU, locations X12 and W12.
Pulling a CB for a windshield wiper is probably one of the options I would do even in flight, even if I may consider returning to departure airfield afterwards, depending on the circumstances (WX on arrival, impact on subsequent flights etc.)
Where on earth some people see no CB's in an Airbus? I hope a rated pilot can make the difference between a pushbutton and a CB...

Speed card is the internal vertical indicated airspeed speed scale on the EADI
to the left of the attitude indicator.
Don't know if there's a dedicated RAT Circuit breaker.

Ok I stand corrected however I did say in brackets that I was sure the 320 was the same. Apparently it's old technology!!
Certainly I was correct with regards to the super modern 330 !!

Well if you look at the top of the page you paste it shows 318 319 320 321 BUT not 330
My 330 QRH calls those little things on the overhead panel Computer reset push buttons. THEY ARE NOT CIRCUIT BREAKERS...
Here is the same page from the 330 QRH:---

ABNORMAL AND EMERGENCY PROCEDURES 15 FEB 13
COMPUTER RESET - GENERAL RESET OF COMPUTERS This table lists the computers that may be reset following abnormal behavior, or a detected fault. Most of the computers' reset capability is provided on the overhead RESET panel: Those with an asterisk* are reset on the system control panel. To reset a computer: ‐ Set the related normal cockpit control OFF, or pull the corresponding reset pb, ‐ Wait 3 s, if a normal cockpit control is used (unless a different time is indicated), or 1 s if a reset pb is used, ‐ Set the related normal cockpit control ON, or push the corresponding reset pb, ‐ Wait 3 s for the end of the reset.
WARNING Do not reset more than one computer at a time, unless instructed to do so.
The following table lists the various computers for which manual reset capability is provided: • On the overhead RESET panels, • On the system control panel. For each computer reset, the table lists the effects and/or precautions where applicable ("NIL" indicates no additional effects and/or precautions apply). ‐ A computer reset has to be attempted when: • recommended by an ECAM procedure or • recommended by a paper procedure. ‐ In all other circumstances, where a failure is suspected or detected, there is no specific recommendations as to whether a reset should be performed or not, except those where a reset is specifically forbidden. Manual reset on ground triggers complete power up test.

Further more:---
Those Circuit breakers you mention, SFCC and ECU etc are not on the 330 overhead panel as such at all.
The Lower Avionics bay contains Circuit breakers on the 330 and that is where those SFCC and ECU circuit breakers would be located for ENGINEERING USE.
Monitored by the CBMU ( circuit breaker monitoring unit ) and available on the C/B SD page on ECAM.
There are also other cabin related circuit breakers in the cabin.
Ok, happy now...

Huh? I did not say you were wrong to begin with. And yes, I can read - thank you! Nitpicker quit nit picking :P
An extract of the 330 QRH
Also, there are some places where you'd need to pull out the CB it seems. But not as many as the 320... The 330 is a newer airplane, doesn't make the a320 ancient
Everything is this post and any other post is to educate myself and not to accuse anyone of what they may or may not know. If any of that may have seemed misdirected to that effect, wasn't the intention.

Ok fair enough mate. I was pointing out to backseatdriver in my post #29 that I wasn't wrong with respect to the A330, you got caught up in the crossfire!!

Equipment cooling system
APU fire extinguishing
Fuel boost pumps
Power Transfer Unit
Ram Air Turbine
Angle of Attack probe heat
Pitot-Static probe anti-icing
Total Air Temperature probe heat
Flight Management Computers
Electronic Engine Control
Engine start system
Air cooling pack system.
And probably other functions as well.
Sorry Stilton, but the Speed Card has nothing to do with SPEED TAPE on ADI´s but all to do with engines and their control. Hence why the RAT drops when both CB´s pulled simultaneously, it thinks both engines have quit.

Did it occur to anyone that resetting a CB for a wiper should be straight pilot decision making? Forget about computer reset tables, a wiper is not a computer....it's a wiper! It does not compute much, apart from OFF/SLOW/FAST which are mechanical (pilot) inputs to the electrical wiring.
Airmanship is the best computer in this scenario, and should dictate when resetting the CB is relevant or not (and especially for the not-computer equipment)
By the way, this situation should not be a reset, but a faulty system isolation by removing its electrical power supply (CB pulled) until the mechanics can have a look.

@FLEXPWR:
There was an earlier post in the thread which seems to have since been edited that implied that there was a list of circuits which could be pulled in flight and that the wiper motor CB was not on it. If this isn't the case, then I retract my earlier statement.

FLEXPWR--- yes it's occurred to all of us. I was mistakingly assuming that the A320 was the same as the A330 in that we don't have C/B's in the cockpit to pull at all. Only computer reset push buttons.
On the A320 they apparently have C/B's in the cockpit and I guess there might be one for the Wipers, if so I see no problem pulling it out under those circumstances.
Don't confuse pulling/resetting a C/B with a A330 style computer reset button used in conjunction with the QRH reset tables.

Well thanks ocean crosser. That explains what happened to this crew then !
I stand corrected.

Where do they stop.
The question in my head is, if you have the option to pull the C/B, where do the wipers stop. Do they stow as they would when working normally or do they just stop in the middle of the screen? If so, then your are still stuck with the 230 knot limit.
I have always been told that it is not my job to troubleshoot. leave that for the techs on the ground. Only situation where its ok to think out of the box is if you get something critical that is not described in the C/L.

Wipers in the MEL say check landing capability.
However in the air, provided you have rain repellant on the PF side, wipers are not a requirement for cat 2 or 3 (b) approaches.
QRH OPS-OPS-4:
You'd have to return if it wouldn't stop running - that's all there is to it - unless you're one of these believers in the 'grey area' - remember as a pilot you have all of the responsibility and none of the authority - the managers keep that for themselves - That's of course unless all bets are off - this isn't the case here.

WINDSHIELD WIPERS OR RAIN REPELLENT (if activated)......number required: 1 on PF side
