Having just done the MK booking system I noted that one area of competency they ask for is the ability to do 'linked turns', do they mean one turn that follows from another - to make a constant S shaped shoosh shoosh shoosh shape on the snow. I can't do this yet but I can manage a turn linked to the end of a short traverse across the hill. Could someone add a description for 'linked turn' please?

Megamum, whilst I wouldn't dare to post anything resembling an opinion on BZK  , maybe the subtext of that question is "are you going to be a hazard to yourself or others?". The ability to "link turns" without saying what sort of turns they are - big high speed turns swooping right across the slope and back may well be "linked" but might not be the safest thing on a crowded beginner slope - seems fairly meaningless, but I'll guess that it's an attempt to describe a degree of control. A quote from the BASI Central theme manual (probably out of date before my throat is torn out by baying hounds  ) may assist you to understand, or it may not. I say nothing, but I have highlighted a little bit.
Quote:
There are two key factors which determine the overall shape and size of a turn: its radius, and its arc length. The turn radius describes the size of the (part) circle round which the skis travel. The arc length is the distance the skis continue round that circle before the new turn begins.
Take the example of someone who is trying to ski precisely within an imaginary corridor. They can achieve this in various ways: at one extreme they might make very long-radius turns, while keeping the arc length short enough to avoid over-shooting the margins of the corridor; at the other extreme, they might make very short-radius turns, but continue round each arc until reaching the corridor margins.
Two things distinguish these different lines: in the former case, the rate of descent is faster, and the vertical distance covered by each turn is greater. In fact, many attempts by skiers to make 'short-radius turns' are actually long- radius, short-arc turns. This is the main reason why so many skiers have difficulty controlling their speed when skiing narrow runs.
At the other extreme, many skiers have difficulty making long-radius, long- arc turns. Instead of allowing the skis to turn gradually, they make quick turns and then allow the skis to traverse before starting the next turn. This leads to a loss of rhythm, and makes each turn harder to initiate.
Unquote.

That explains, why, when I'm stood at the top of the hill with fellow BASI colleagues, and I suggest some short radius turns, they ask,
short radius, long arc, or long radius, short arc.

And demonstrate the subtle use of skidding to wipe off speed 
bit confusing this as the skis appear to deviate the same distance from the fall line in both cases - maybe they meant "across" the fall line

Great work here.
How about 'A-Frame' and 'sitting in the back seat'? I've seen them mentioned quite a lot (in a negative way) but I'm not sure what exactly they mean. Are they general terms or just Snowheads terms?
'A-frame' seems to be something to do with leg shape below the knee but I wouldn't know if I'm doing it or not.
'Sitting in the back seat' I'm guessing is leaning forward by sticking your rear out, the cure for which, as someone brilliantly and succinctly put, is to think 'shag, not sh#t'.
[EDIT - Oops, backseat is there]

Jeraff, 'A frame' is a good one, i will add my 2 pennies but a framing is a debatable term. Back seat is already there BTW...
A - FRAME - The position that a skiers legs gets into when the outside leg's knee collapses into the inner knee when turning, or, when the inner knee is not angulated into the centre of the turn. Is typically (but not always) seen as a problem to be eliminated when skiers are using shaped skis as can be a "weak" ski position.

skimottaret, yep, I spotted the 'backseat' after posting, hence the [EDIT...]. But I still wanted to repeat the 'shag, not sh#t' comment (oh I did it again)

skimottaret, maybe add to the "Plough Parallel" definition OPS's comment that rotation of the ski brings the tip in and the tail out to regain the plough shape, as otherwise your "Plough Parallel" remains stuck in the parallel phase and there is no transition to the next turn, unless the next turn is a parallel turn of course ? And is it not the case that similar rotation but in the opposite direction brings the skis parallel from the plough shape? That's if you agree of course

Yoda, I agree and have already tried to put his comment in a couple of days ago.... i came up with the following, what do you recon? i am rubbish at plough parallels BTW....
PLOUGH PARALLEL TURN - A turn that starts in a plough and as the turn finishes the inside ski is rotated about the foot to match the outside ski and form a parallel shape during the transition to the next turn. To start the next turn the skis are rotated about the foot to bring the tips inwards and the tail outwards reforming the plough shape going into the next turn. The outside leg is extended at the beginning of the turn to initiate pressure.

David Murdoch, in a stem the axis of rotation is through the tip of the ski whilst in a plough parallel it's through the centre (foot). Some folk have the same problem with short swings, where the rotation occurs around the tips instead of the feet (I have this problem )
skimottaret, not bad, maybe "initiate pressure" could be something like "start pressurising the new turning (i.e. outside) ski"?

A more BASI-like sentence would read:
To start the next turn the skis are rotated about the foot to bring the tips inwards and the tail outwards, reforming the plough shape going into the next turn. Balance is then established on the (new) outside ski to progressively build pressure through the turn.

Yoda, I don't see how the axis of rotation can be through the tip - as there's nothing anchoring it? Surely in any skidded turn the axxis of ski rotation is roughly around the feet?

David Murdoch, "axis" is the hinge or fulcrum point of any rotational moment on a plane. It can be variable when applied tin this case to skiing as there is a lateral factor
|

|

|
|
Masque, sure, but in the skiers Frame of Reference I don't see how you can rotate around either the CoM or a fixed point and in most cases this won't be through the tips of the skis?

David Murdoch, On my ASSI course the plough parallel technique taught was, just before the end of the plough turn, to slightly lift the tail of the inside/uphill ski up & step it parallel with the outside/downhill ski, effectively pivotting it around the tip of the ski. Once mastered this move is progressively repeated earlier & earlier in the turn.

spyderjon, that isnt a plough parallel turn technique, that is a stem christy turn. Did you do your assi on plastic? if so plough parallels are very hard to do on that surface IMO and most teach stem turns.
Is it a good idea to demonstrate to beginners lifting the inside ski and step it over?

Yoda, skimottaret, spyderjon, Gotcha - with the aid of the SNSC Central Theme PDF I see what you mean. Ta. For the avoidance of doubt Stem = extension out of foot into a plough to aid initiation | PP = rotation of ski about foot from plough to parallel??

spyderjon, hmm... sorry dont want to sound like i am having a go at you but it doesnt sound good to me that they are teaching instructors to demo stem christies on snow as opposed to PP's ... sounds like your ASSI tutor needs to emphasize central theme more instead of "old school" techniques....

Javelin Turns - A drill which is performed by completely lifting the inside ski from the snow and pointing it across the outside ski. The inside ski is lifted off the snow at or before the edge change of the new outside ski. At the end of the turn the inside ski is deliberately placed back on the snow and then becomes the new outside ski.
Charleston Turns – A drill where the skier performs a series of short radius turns on the inside ski while keeping the outside ski off the snow. Done well it it very rhythmical and looks like the Charleston dance step.

Crust - A hard snow surface lying upon a softer layer; crust may be formed by sun, rain or wind, and is described as breakable crust or unbreakable crust, depending upon whether it will break under the weight of a turning skier.
