Many Moons ago a directive was issued by Airbus expressly forbidding the setting the park brake inflight. This followed an incident when an aircraft landed and the brake was still set 
This has potential to wreck the noseleg due to the rapid derotation of the aircraft (cos the mains aren't turning...)
I don't know if the handle was in the "SET" position - but the parking brakes were! If it was a software issue, it's probably been sorted by now.
Safest bet is don't touch the PB handle in flight.

i think the ? is expatula, if for some bizarre reason some numb nut set the parking brake which is only a switch on the airbus will the ecam give a warning to say such.
whereas the boeing and i speak only from 737 experience you have to press the toe brakes and then set the parking brakes.
i also would like to know considering the ? is asked, will you get a warning on the airbus if the park brake is inadvertantly set in flight?

I've heard that it can also be set on the 737 ,and it won't be possible to set it off again.
..
I've heard one cpt did it,and it had to declare an emergency before landing,thinking that the tyres will blow at contact. To his luck,it seems that Boeing thought about such smart,playfull pilots,and the parking brake disabled itself at touchdown,normal braking after that.
Expatula,why would you set parking brake inflight? Well,what if you have to wait at a crossings,for the train to pass? .We even shutdown the engines,it's standard SOP,just to save fuel..

Watched a Victor land at Boscombe Down with the park brake set. All tyres shredded spectacularly.
The Victor gear was such a neat fit in the wells that there had to be a method of stopping wheel spin. To achieve this the designers fitted the park brake selector to cover the gear up selector forcing the crew to apply park brake before up selection. The ineviatble happened.
Doing a few touch and goes involving some braking before the go again on an 11,000 feet runway the pilot started the gear retraction sequence only to change his mind about the retraction having already applied the park brake. Result - lots of loss of face and rubber!!
Cannot recall how the problem was rectified.

You got it right.
And vapilot2004 :this can't happen in a 737,as I've said the parking brake will disable at touchdown.The plane in the picture is not a 737,it's a E170 (something missing on the tail picture,got it?..)

how could you explain that?
that's one thing i will leave alone.
God, that must have been hard to deal with in the next job interview.
he/she probably became an FAA aviation safety inspector!!!!

The A320 Park Brake can definitely be selected ON during flight.
ECAM will display PARK BRAKE ON in red as a reminder that this is not a good configuration for landing.
The only real danger playing with Park Brake handle in flight is that after the selection of gear down the Park Brake Control Valve may be stuck in the open position or the handle may still be giving ON orders.....
On the ground I have personally experienced the A320 Park Brake Control Valve sticking in the OPEN position. It could only be released by a powerful blow with a wrench by engineering.
