Trick
Backside Cork 540
GLOSSARY
A backside cork 540 is one and a half backside rotations on a tilted axis, so the body goes partly sideways or upside down during the spin. It is learned after a controlled upright backside 540.
Context and distinction
A cork tilts the spin's axis; a flat backside 540 stays upright. Rotation amount and axis are separate parts of the name.

Backside Cork 540
A backside540 with displaced rotational axis in the cited source; tilt depends on the version.
Preparation and setting
ControlledBS540 and coached off-snow orientation; no automatic transfer from trampoline to a snow jump.
Known phases / unresolved execution
- Separate trampoline and snow descriptions.
- The off-snow lesson relates lead-arm/shoulder action toward the rear-foot region to axis change.
- The snow example uses a backside approach and toe departure.
- Identify theBS540-like landing recognition.
- Obtain feature-specific coached departure and recovery details before reproducing it on snow.
Learning and practice
Develop spatial recognition under supervision and retain a controlled upright540 as a separate competence.
Errors, limits and corrections
Copying a trampoline impulse onto snow or forcing tilt to meet a label is unsupported.
Observable checks
The direction, tilt and switch landing are documented without claiming a validated standalone pathway.

Characteristics
- Training context
- trampoline: lead arm/shoulder toward the rear foot to explore the axis; snow: BS approach, coordinated upper body, toe-edge departure (S3)
- Take-off edge (example)
- toe edge in S3's snow example
- Source-recommended preparation
- Backside 540 (S3)Inversion familiarity (S3)
- Provider training topics (index only)
- Backside Cork 540 (I05) — SITE Wanaka index (S1) — provider_index_confirmed; technique not reviewed
01
Additional teaching summary — coaching review required
The source develops the movement off snow, requires established Backside 540 control and connects lead-arm/shoulder action to an adjustable degree of axis displacement.
02
Additional editorial review notes
The source describes variable off-axis motion rather than one fixed inclination.
03
Additional teaching summary — coaching review required
S3 (written): the trampoline discussion uses lead-arm/shoulder movement toward the rear foot to explore the axis; the snow example combines a BS approach, coordinated upper-body action and toe-edge departure, with landing recognition related to BS540. The lesson discusses changing the degree of off-axis movement — it does not justify one rigid axis for every Cork.
