This turn-entry drill can be compared to the pipe entry, where the body center of mass has to travel forward and down into the pipe before the skis move even an inch down the wall. Got it?

Now, take this visual clue and put it into a slow motion, really slow motion, and imagine that the pipe has been ironed out to form the blue terrain you're standing on.  What's left out of it is still the fact that YOU go first and the SKIs follow and that YOU have to wait for the SKIs to react.

There is one other difference between the usual pipe entry and our blue terrain drop-in drill.  You will start this drill from a full stop, parrallel, cross fall line position. Additionally, we'll limit your anticipation movements to 11 o'clock for the left and 1 o'clock for the right drop-in turn.

Having noticed that most Olympians started their runs off the left bank, we'll use the same direction for our first "paper" turn here:

To peak into the imaginative pipe wall (don't worry, you're still on the blue square) you are going to bend your ankles and start moving your core forward and towards your 1 o'clock.  Make it 10 to 1, never 5 past.  While doing so you will feel your shins push harder on the boot tonques and your skis roll from "edges set and hold" position towards "I am losing my grip feel".

That's all great! Relax ... seriously! Extend your body, relax your edge hold and let the skis pivot towards the fall line. 

If you're going on flat skis down the fall line you've completed your Drop-In drill and can stop, now. I mean, NOW, please.  Thanks!

How do I know I have done it well, you may ask.  Well, let's review the drill objectives and maybe propose some mini-progressions to make sure that we've nailed it.

Drop-in Objectives:

1. Move your body center of mass forward and ahead of the center of pressure to create angular momentum that will pivot your skis towards the fall line. Relaxing the edge hold will help decrease the rotational friction and you can accomplish more with less, so to speak, if you relax your edge hold.
2. Tails displacement should be minimal to none, while tips displacement extensive.
3. There may be some patiently distributed feet rotary movement but only to finess and showcase the tips drop displacement.  Again, tail displacement kills your score.

Checking points:

1. Have your buddy or instructor watch your tail displacement and critique your stance and movement.  Many times you don't realize what you're doing or not doing and need this feedback.
2. Walk up the hill to inspect your trail.

Description/Prescription:

• Pushing on poles (unnecessary and against the objective of maximizing tips displacement in a shortest distance covered)
• Looking down (trust me: the skis will be there when you finish, so keep your head up to mimimize the rotational inertia, maintain proper balance and situational awareness; look at the treetops at the bottom of the hill and negotiate with the skis, the snow and the hill using other than visual senses and cues)
• Hands hanging low - hold your hands around the hoola hoop where they belong (yet another ski drill) - they will contribute to your better balance in addition to moving your center of mass forward.
• Holding too much edge causing skiouts off the drill zone - at first, the drill zone can be as wide as you desire but it will have to be as narrow as the length of your skis to call home.

Dynamic Drop-In Mini-Progressions:

• Parrallel Entry; sliding your fritas de papa accross the fall line engage and disengage your edges in rythmic movements leaving clean track of swoosh, then dos fritas, then swhoosh and then again two rails strongly imprinted on the snow, sharp as razor blades.  Then finally use more dynamic knee rollover with stronger body throw towards the fall line maybe with a bit stronger, yet still patient, feet rotation to make the tips displacement bigger.  Keep the skiis as flat as possible during the pivoting segment and ski straight down the fall line to collect the style points.  If you can do this - YOU've nailed it!
• Leaf drop aka Tailslide; imagine, your skis come up the hill like a glider looping up towards the sky; 1/4 looping up, close to vertical until the glider loses momentum. The glider falls backwards, the nose drops through the horizon to the vertical, 1/4 loop to recover. 
  • Visualization: click here, then select Tailslide Aresti symbol, chose player, then optimal viewing angle (Main).
• Hammerhead or Stall Turn; gliding up the hill towards the vertical, as momentum/airspeed decreases, rudder is applied and the glider rotates around its yaw axis, the nose falls through the horizon and points towards the ground, a momentary pause is made to draw the vertical down line, and 1/4 loop to level flight. This figure is sometimes called a stall turn which is a misnomer because the glider never actually stalls. 
  • Visualization: click here, then select Hammerhead Aresti symbol, chose player, then optimal viewing angle (Main).
• 360 Loop; is similar to the Hammerhead but requires continuing the turn through the vertical in the same direction.  Finess of the invisible touches to your balance scores the highest points.
