Rules for the Official IGC World Pilot Ranking List

Overview

The ranking list has two components: Pilot Rating and Competition Rating.

The Pilot Rating is the result of his performance in IGC sanctioned competitions.

The Competition Rating depends on the type of competition, the quality of the pilots competing and the number of competition days. The Competition Rating is reduced when the next competition in the sequence is completed and will no longer apply after second in the sequence.

The rating is expressed as a number from 0 to 1000 for both pilots and competitions.

1 Competitions

Most competitions included in the Ranking List will be members of a sequence of competitions held regularly, annually or biennially. Each competition can have several qualifying competitions, one for each separately scored class in the competition.

The ranking list includes results from all sequences of IGC International Competitions plus any sequence or any one-off competition sanctioned by the IGC for ranking list inclusion. For advice on competition approval see about Sanctioned competitions.

For ranking purposes, competitions are divided into the following categories:

· Cat 1+: First Category FAI Competitions such as World Championships in each of the FAI classes.

· Cat 1 standard: First Category FAI events with restricted entry and continental championships, or any other international event approved by IGC as First Category.

· Cat 2+: International Competitions or Open National Championships with international participation in accordance with Section 8 Competition Qualifications below.

· Cat 2 standard: Open national championships or international competitions not complying with Cat 2+ requirement as of Section 8 Competition Qualifications below.

Ranking is updated after every competition is finished.

2 Active Competition Period

A competition will remain active until two following competitions in the same sequence have been completed, but for not more than 4 years.

If a sequence of competitions comes to an end, or no longer qualifies for IGC Ranking, the competition will have a reduced Quality Factor one year after it was last held, and zero on the second anniversary.

3 Competition Rating

Competition ratings are calculated using the ratings of the 5 pilots finishing in the top 15 with the best ratings (or first half for competitions with less than 30 entries).

Competition Rating = 0.1 x (5 x Maximum_ Rating[i] + PR1 + PR2 + PR3 + PR 4 + PR5 + 100)

PR=Pilots Rating

The competition rating is limited within the range appropriate to the competition category outlined below

IGC Pilot Ranking System

Competition category	Cat 1+	Cat 1 std	Cat 2+	Cat 2 std
Maximum Rating	1000	980	960	960
Minimum Rating[ii]	960	900	800	800
Pilots Rating min	900	800	620	620

4 Competition Quality Factor

The maximum Rating a pilot can achieve from a given competition is limited by the quality factor. The quality factor considers, number of competing pilots, number of competition days, the competitions category and its position in the sequence.

A sanctioned competition’s Quality Factor is reduced after the next Competition in the same Sequence is completed and reduces to zero when a second Competition in the same Sequence is completed

Base_quality_factor	Cat 1+	Cat 1 std	Cat 2+	Cat 2 std
Latest competition in a Sequence	80 %	80 %	70%	50 %
Preceding competition in a Sequence	60%	60%	50%	30 %
All other competitions in a Sequence	0	0	0	0

Entry_factor = number of pilots (with score > 0) in competition / 15 (limited to 1)

5 Pilot's Competition Rating

All competing pilots in a sanctioned Competition will receive a rating score from that competition.

The competition winner’s Rating is equal to the Competition’s Rating. All the other competing pilots receive a rating proportional to their final score.

Rating_score = Competition_rating x Pilot’s final score / Winner’s final score

6 Pilot’s Rating points calculation

The Pilot Rating is calculated from the best Rating Scores achieved, taking into account the Competition Quality Factor. Only two Cat 1 competitions may count towards the Pilot Rating[iii]. It is calculated as follows:

Keep the best 2 Cat 1 competitions (those which yield pilot the best overall rating). Discard all others based on Cat 1 competitions. Keep all Cat 2 Competitions without any number limitation.

Add a « virtual competition[iv] » whose rating score is pilot’s best rating minus 200, with a Quality Factor of 1.

Sort all pilot’s Competition Scores (Rating Score along with associated Quality Factor) by decreasing order of Rating Score.

Uncorrected Pilot Rating = S (Pilot Rating Score x Quality Factor)
{Until the sum of Quality Factor >= 1}

If the sum of Quality Factor > 1, then reduce the last Quality Factor so that the sum of Quality Factor becomes equal to 1

If Virtual Competition was used in this sum, subtract 1% of (Virtual Competition Rating Score minus next Competition[v] Rating Score) [vi])

7 Pilot Ranking

Pilots are ranked upon decreasing Pilot Rating. Ties are broken by the previous place in ranking list

8 Competition Qualifications

· First Category competitions shall follow IGC rules (SC3, Annex A), including Jury, stewards and Public Relation Officer requirements, any deviation to the rules (task type, scoring, etc.) shall be declared when applying for Ranking and approved by IGC reduced with competition

· All IGC Competitions of Second Category, are eligible to be included in the Ranking system.

· Second Category competitions shall be organised by or under the authorization of NAC’s. Open second category competitions may be designated 2+ for the Ranking List formula

· Category 2+ must include participation by pilots from at least 3 FAI NAC’s.

· Except for Cat 1 IGC competitions, organizers should apply for their competitions to be approved for IGC Ranking approval 3 months prior to the event.

· The Ranking list sanction fee as determined by IGC, shall be paid before beginning of the competition.

The officially accepted entry list and results of any competition shall be received by the Ranking List administrator within eight days of the end of the event. Results shall include every competitor's Ranking Identifier and comply with the format specified by the IGC, so that the updated Ranking may be calculated automatically. If a pilot is not previously registered in the Ranking, his Ranking Identifier will be allocated by the Ranking List administrator.
