Disco sliding with handbrake on in Snow in Ice
Ok so this is the first time I have had the Disco 3 sliding in snow and ice in snow and ice driving mode with top notch winter tyres and the hand brake on, anything else I should be doing (and wasn't going fast just trying to get out of someone's driveway and came very close to hitting the wall a couple of times so left it there overnight). This sounds pathetic but I am an experienced snow driver but don't think -5C helped. In the past this F*ker has been invincible in such circumstances

well once I started sliding sideways I put the handbrake on, normally that solves it (also in my 14 year old 911 turbo 4x4)

If the wheels were locked I would say it was frozen ice. If the wheels were still turning I would say your EPB needs adjusting. If it still did it when the foot brake was applied (assuming very low speed) I would definitely say sheet ice.Discovery 4 HSE

Is there another type of ice other than frozen?

I've seen fully laden 8x6 trucks slide down the road with the brakes on and disappear into a ditch, gravity and no friction are a humorous combination. Best method is to allow your wheels to start turning and try and gain some control back. Cadence braking is still an effective method even with ABS.De-Tango

Knock it into neutral so that there is no drive to the wheels whatsoever is also a good idea (or depress the clutch on a manual car).

Though it won't defy the laws of physics. ISTR on a forum outing to the Lake District we were all parked up waiting patiently on DiscoDunc pulling a FFRR out of a ditch (picture deep snow all around) when one parked car started sliding downhill. Luckily then car in front stopped the slide.

Better change the tyres for 2mm ones so it's smoother on the ice as well
I understood that if you put the handbrake on when moving, then depending on the speed, the car will do an emergency stop with normal brakes and then apply the EPB once the speed is below a certain speed (5MPH??)Mark.

Is this advice from 1975 ?
The emergency application of the handbrake requires you to pull and hold on the lever ...it then applies normal braking and ABS to all 4 wheels until released ...try it at 90mph 21 year LR veteran > D2 GS 2003 > D3 S 2006 > D3 HSE 2009 > D4 HSE 2013 > D4 HSE 2015 > D5 HSE 2018 > DS HSE R-Dynamic P300e 2021

At what point does thawing ice become unfrozen? I'm sure the Scientists amongst us will explain the theory behind it all.
I was trying to establish if it was sheet ice (almost impossible to control a vehicle of any description on) Or slushy ice, relatively easy to control a vehicle even without 4 wheel drive or terrain response.Discovery 4 HSE

When it melts and changes state, changes from solid to liquid. I'm an scientist, well was. Though most peeps dismiss geologists as not being scientists, but we know better.
PS Don't forget the colder the ice is the more grippy it is. Sheet ice at around 0c is the worst coz it's like driving on a wet ice cube. Same at -20c will be dry and give lots of grip.
