It's Amber, not RED...
Of course it can be set "ON" in flight. And you will get an ECAM memo - PARKING BRAKE (in amber, not red)! This is just an advisory, not a warning. And also your triple Y indicator will show that it is pressurized.

From your post at #10 - "On the old VC10 the park brake could be set to park in flight, and then one day someone did and when it was landed it blew all 8 main wheel tyres."
I guess you are talking about civilian operated VC10s. You might be interested to know that the VC10s that the RAF bought direct from Vickers in the early 60s had (and still have) a 'hold off valve' that prevented the bark prakes being set whilst airborne, even if the handle was set to park. You would probably have to land, set the brakes off and then reapply them to get them to work. Not that I recall anyone ever doing it but I believe the RAF requested the mod from Vickers to prevent accidents.

From your post at #15 - "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."
"Cannot recall how the problem was rectified."
Are you talking about the Victor B1 or B2? This certainly was not the case on the Victor K2. Brake selector and gear selector were no where near eachother so I guess a redesign was part of the fix? Good old fashioned RAF landing checklists TENDED to include a "Brakes off" somewhere in them.

The Victor was the first to Boscombe Down. Expect the park brake/gear selector was soon rearranged after the multiple tyre changes. Cannot recall whether the rims suffered but expect so.
Probably the shortest Victor non-roll-out ever!
TP was Len Prudence. When he left BD at tour's end he and family flew civil into Europe somewhere. At destination he found his baggage contents missing and replaced with rocks.
Where are you now Len?

Victor parking brake
I worked on K2's for a number of years and the wheels were stopped rotating during the up selection by sending hydraulic pressure down the brake return line. This was all part of the up selection and required no further switch selections. (Seem to remember pressure remained to return line until down selected, which was a real pain for potential hyd leaks.)
