The International Gliding Commission (IGC) is a leading international governing body for the sport of gliding
Gliding
Gliding is a recreational activity and competitive air sport in which pilots fly unpowered aircraft known as gliders or sailplanes using naturally occurring currents of rising air in the atmosphere to remain airborne. The word soaring is also used for the sport.Gliding as a sport began in the 1920s...

Badges

In the early 1920s two flying organizations, the Association of the German Model and Gliding Clubs, and the Rhön Soaring Association
Rhön-Rossitten Gesellschaft

, determined that pilots would be listed as "A" level if they flew a glider for either 300 meters or 30 seconds, and "B" level if they made two flights of 45 seconds in straight lines plus one of 60 seconds in an "S" pattern. (It should be remembered that these flights were made by bungee cord

 launches down hillsides.) In time a "C" level, requiring a five minute flight, was added. A few years later Fritz Stamer, chief flight instructor of an early gliding school, designed the gull insignia which were used for these awards and later for the badges.

ISTUS (Internationale Studienkommission für motorlosen Flug), was founded in Frankfurt on 13 June 1930, to record international gliding achievements. The founding nations were Belgium, France, Holland, Hungary, Germany, Italy, and the USA. A series of badges for gliding was devised called A, B, C, D etc.

Later the D badge became known as the Silver C, and more often today just the Silver Badge. Earning the Silver C Badge shows that a glider pilot has achieved an altitude gain of at least 1,000 m, made a five-hour duration flight, and has flown cross-country for a straight-line distance of at least 50 km: these three attainments are usually, but not invariably, achieved in separate flights. The first recipients of the Silver C were Wolf Hirth

 on 15 February 1931.

In 1932 the FAI recognized gliding, and formed a new section: the Commission Internationale de Vol à Voile (CIVV). This eventually took over the role of ISTUS. The FAI decided that the Silver C was sufficiently meritorious to be internationally recognised, and issued the first 300 before turning the awarding over to the national societies. From the beginning the lesser badges were only recorded by local gliding associations, and their criteria varies, although they are usually integrated into organized training programs. For example, in the United States a Bronze Badge is issued for demonstrated pre-cross country flying skills beyond the C level. In Britain a pilot progresses from the B to the Bronze level and then receives an additional endorsement for cross-country training.

The E badge (later called the Gold C and now usually just the Gold Badge) was established in 1935. A pilot who has completed the Gold Badge has flown 300 km, though not necessarily to a pre-defined goal, gained 3,000 m in height and has made a five hour flight (only one has to be done to count for both the Silver and Gold). Up to this level the badges are registered only by the national gliding associations.

The F Badge (now the Diamond Badge) started in 1949. The Diamond Badge requires three achievements: flying 300 km to a pre-defined goal, going 500 km in one flight (but not necessarily to a pre-defined goal), and gaining 5,000 m in height. Earning all three "diamonds" qualifies the pilot for the FAI registry as a Diamond Badge holder. The FAI also issues a diploma for a flight of 1,000 km and further diplomas for increments of 250 km.

Gliding records

The wide variety of records have been defined by the FAI Gliding Commission. The classes of glider

Competition classes in gliding, as in other sports, mainly exist to ensure fairness in competition. However the classes have not been targeted at fostering technological development as in other sports...

 have been combined into four groups: Open, 15 metre, World Class and Ultralight. Although female pilots can claim world records in these general categories, there are also additional records in these categories just for female pilots. Because of the number of records the table below only summarises some of the Open Category gliding records as at the beginning of 2008. A full list is available on the FAI web site.

GNSS flight recorders

With the advent of satellite navigation equipment at an affordable price, the International Gliding Commission of FAI developed a technical specification
for approved flight recorders. The IGC-approved flight recorders provide precise evidence of position for competitions, world records and FAI awards and other activities. The replace earlier methods of observation that used photographic evidence or ground-based observers to record aircraft position. The IGC-approved recorders include a pressure altitude sensor and a Global Navigation Satellite System (GNSS) receiver. They also include data output in a standard ASCII-based format, the "IGC flight data format". This format is used in files with the suffix "IGC" that is specified in detail in Appendix 1 of the document "Specification for IGC-approved GNSS Flight Recorders" that is available on the IGC GNSS web site. It should also be mentioned that organisations outside IGC also use IGC-approved flight recorders and the IGC flight data file format.

In IGC-approved recorders, GNSS and pressure altitude data is continuously recorded during flight in the form of regular fixes stored in non-volatile memory
Non-volatile memory
Non-volatile memory, nonvolatile memory, NVM or non-volatile storage, in the most basic sense, is computer memory that can retain the stored information even when not powered. Examples of non-volatile memory include read-only memory, flash memory, ferroelectric RAM, most types of magnetic computer...

 inside the recorder. Typical fix intervals, set by the pilot before flight, are between 5 and 15 seconds for "cruising" flight between turn points, and between 1 and 2 seconds at or near turn points or other points of interest.

The pressure altitude system in an approved recorder has the same function as a barograph
Barograph
A barograph is a recording aneroid barometer. It produces a paper or foil chart called a barogram that records the barometric pressure over time....

 and must be calibrated to the ICAO ISA (International Civil Aviation Organisation International Standard Atmosphere). Re-calibrations to check any errors from the ICAO ISA are carried out at regular intervals in the same way as an analogue barograph that uses an aneroid pressure sensor rather than an electronic pressure transducer. Recorded GNSS fix data replaces the need for photography to certify the track over ground and in particular whether a particular turn points has been reached. GNSS altitude data can be compared after flight with the pressure altitude data from the independent sensor in the recorder and this is a valuable check that both systems are working correctly.

In March 1995, the IGC created their "GNSS FR Approval Committee" (IGC GFAC) to test recorders for compliance with the Commission's rules, the FAI Sporting Code Section 3 (Gliders and Motor Gliders). GFAC also issues IGC-approval documents for approved types of recorder and these documents are posted on the IGC GNSS web site.

For IGC-approval, the recorder design includes adding a security code to the downloaded file of flight data. This code and the file data itself can be checked ("validated") at any time later using a validation program originating from the recorder manufacturer that is posted on the IGC GNSS web site for general use. This validation program checks three things. (1) That the file has properly originated from an approved type of recorder, (2) That the recorder has not been altered from its IGC-approved state, (3) That the data in the downloaded file that is being validated is identical to when it was originally downloaded form the recorder. This allows the data to be used for the validation of flight performances up to and including world records.

There are three levels of IGC-approval and at the higher levels a public/private key encryption system such as RSA or equivalent is used to achieve the validation process above. Recorders at the higher approval levels also have a security device such as a microswitch that operates if the recorder is opened. This enables unauthorised modification to the recorder to be detected and protects the integrity of its output data.
