31 = Removal of wind reference in Cloverleaf Slalom

Proposal from

Andy Phillips GBR

Proposal title

Removal of wind reference in Cloverleaf Slalom

Existing text

S10 An4 3.C5

Objective

To strike a number of targets laid out in a given order in the shortest possible time and return to the deck.

Description

4 pylons 2m in height are laid out

- At the corners of a 70.71m square for PF1 and PL1 classes.

- At the corners of a 100m square for PF2 and PL2 classes.

A fifth target is set at the centre of the square.

The pilot enters the course into wind and strikes the target T (strike 1). At this point the clock starts. The pilot flies around pylon 2 and returns to kick the stick T (strike 3), he then flies around pylon 4 and returns to kick the stick T (strike 5). This continues until all four pylons have been rounded. The clock stops when target T is kicked for the last time (strike 9).

[There is currently a wind direction arrow on the associated diagram].

This continues until all four pylons have been rounded. The clock stops when target T is kicked for the last time (strike 9).

[The wind direction arrow should be removed from the diagram].

Reason

The direction of entry to the course should be at the pilot's discretion. The current wording puts the onus on the organisers to correctly assess the wind direction for each run. If the wind direction varies during a task, it should be up to the pilot to decide the best direction to enter the course.

Another key reason is that some pilots prefer to enter the course downwind as they consider the combination of downwind and into wind turns to be safer, particularly in a breeze.

In Past competitions, pilots have entered the course NOT into wind without penalty, so the precedent has already been set and there is no value in keeping the potentially troublesome "into wind" stipulation and graphic in place.
