FAI badges are international standards of achievement in gliding which have been established since the beginning of cross country flight, some time early last century. Flights qualifying for badges are controlled in accordance with the requirements of Section 3 of the FAI Sporting Code.
More information on badge flying and badge claims can be got from the FAI or the GFA website. It's important to get the facts on badge flying before you set out on your task to avoid the disappointment of having a claim refused because of some technicality so check with the FAI official documents before heading out on that 1000 km task. For those who cannot be bothered to look too far, the relevant section of the sporting code is here.
The soaring performances required to qualify for the FAI badge standards of achievement are as follows:
The Silver badge is achieved on completing the following soaring performances:
Silver Distance a flight that includes a leg of at least 50 kilometres. This leg may be part of a longer declared flight. The loss of height (4.4.3) is calculated on the entire flight, not just on the portion claimed.
Annex C-2.2 gives examples of how this loss of height is calculated. Note: the Silver distance flight should be flown without navigational or other assistance given over the radio (other than permission to land on an airfield) or help or guidance from another aircraft.
Silver Duration: a duration flight of at least 5 hours.
Silver Height: a gain of height of at least 1000 metres.
The Gold badge is achieved on completing the following soaring performances:
Gold Distance: a distance flight of at least 300 kilometres.
Gold Duration: a duration flight of at least 5 hours.
Gold Height: a gain of height of at least 3000 metres.
There are three Diamonds, each of which may be worn on the Silver or Gold badge, and the badges for flights of 750 kilometres or more. A Diamond is achieved by completing one of the soaring performances below:
Diamond Goal: A goal flight of at least 300 kilometres over an out-and-return course (1.4.6a) or triangular course (1.4.6b).
Diamond Distance: A distance flight of at least 500 kilometres.
Diamond Height: A gain of height of at least 5000 metres.
Badges and Diplomas for flights of 750 km and more
These are a family of badges that are achieved on completing a distance flight of 750 kilo- metres or more, in increments of 250 kilometres (ie. 750 km, 1000 km, 1250 km, etc.). One badge is awarded per flight for the incremental distance immediately less than the distance flown.
