Proposal from
CIMA President
Proposal title
Add the option of inflatable pylons to Chinese slalom
Existing text
S10 An4 3.C7
Objective
To strike a number of targets laid out in a given order in the shortest possible time and return to the deck.
Description
Between 6 and 12 targets are laid out on a course not exceeding 3Km in length. Targets are sticks.
The pilot enters the course into wind and strikes target 1. At this point the clock starts.
The pilot then flies the course to strike all the other targets in the given order, a strike on the last one stops the
clock.
Special rules
- A valid strike on a target is:
EITHER one where the pilot or any part of the Paramotor has been clearly observed to touch it.
OR when electronic ‘kick stick’ sensors which have been shown to meet the standard tests are used, a valid
strike is one which is recorded by the device. - A strike on target 1 starts the clock, a strike on the last target stops the clock.
- Pilots may have only one attempt at striking each target except for the first and last targets where three
attempts at each are permitted. - Failure to strike the first or last target or at least two of the intermediate targets or touch the ground at any
point between them: score zero.

Objective
To strike a number of targets laid out in a given order in the shortest possible time and return to the deck.
Description
Between 6 and 12 targets are laid out on a course not exceeding 3Km in length. Targets are sticks, intermediate targets may also be inflatable pylons.
The pilot enters the course into wind and strikes target 1. At this point the clock starts.
The pilot then flies the course to strike all the other targets in the given order, a strike on the last one stops the
clock.
Special rules
- A valid strike on a target is:
EITHER one where the pilot or any part of the Paramotor has been clearly observed to touch it.
OR when electronic ‘kick stick’ sensors which have been shown to meet the standard tests are used, a valid
strike is one which is recorded by the device.
OR if a target is an inflatable pylon, when the pilot crosses the line on the ground with its apex at the pylon and orientated symmetrically to and remote from the two legs of the course at the pylon. (ref. GS A13.1 but without the 90 deg quadrant) - A strike on target 1 starts the clock, a strike on the last target stops the clock.
- Pilots may have only one attempt at striking each target except for the first and last targets where three
attempts at each are permitted. - Failure to strike the first or last target or at least two of the intermediate targets or touch the ground at any
point between them: score zero.
Reason
Now that inflatable pylons are becoming more common at championships, there is no reason why they can't be used in this task too. They were used in this task at ABG but since pylons can be approached in many different directions the question arose 'what makes a valid strike on a pylon?'. The solution used is based on the classical FAI observation zone described in GS A13.1 but simplified to have just a line rather than the 90 deg quadrant.
It worked well, this proposal attempts to define the idea permanently.
