\begin{document}
This document contains all definitions required to score centralised
cross-country competitions for both hang-gliding and paragliding. Its main
purpose is to serve as an addendum to section 7A of the FAI sporting code.
Additionally, it should serve as an educational tool for all parties involved
in such competitions, as a reference for the implementation of scoring systems,
as well as a basis for future improvements and modifications.

\subsection{Scope}
This document’s scope is restricted to scoring of FAI Category 1 cross-country
competitions for hang-gliding and paragliding: World and Continental
championships in both sports. CIVL’s rule setting targets these competitions
exclusively, whereas organisers of FAI Category 2 competitions as well as
non-sanctioned competitions are free to score their competitions however they
like. Most of them do follow CIVL’s lead, though, so this document should also
cover the majority of Category 2 events as well.

The appendices of this document expand the discussion to cover how parts of GAP
have been implemented but they do not form part of the rules.

\subsection{Differences between Hang-Gliding and Paragliding}
Initially, both hang-gliding and paragliding competitions used the same system
for scoring, generally known as “GAP”. But over time, through their two
separate sporting codes, the two disciplines introduced more and more changes
that would only apply to one, but not the other. This mainly in non-standard
situations such as stopped tasks, pilots landing just short of goal, or pilots
crossing the start line too early. Where not explicitly stated otherwise, the
contents of this document always apply to both disciplines. Definitions
applying only to one, but not the other, are clearly marked as such.
