FAI Badges are an international gliding qualification. The FAI Sporting Code describes the rules that must be followed in order to achieve the badge. The relevant documents that outline the rules are:
The rules for badges are listed in FAI Sporting Code Section 3 – Gliding CLASS D (gliders) including Class DM (motorgliders) and the Official Observer and Pilot Guide (Annex C). All badge flights need to have an Official Observer.
Silver and Gold badge flights must be recorded either by a:
An internet declaration is:
Badge Claims are submitted electronically.
Diamond badge flights and above may only use a flight recorder.
Example 1:
Logger: IGC GPS
Distance flown for leg = 105km
Release Height = 4000 ft
Height at the fix or turnpoint = 2500 ft
LOH = 4000-2500= 1500 ft = 457m therefore no loss of height penalty
Example 2:
Logger: Barographic data only
Distance Flown for leg = 55km and landing at that point (i.e. 55000m)
1% of 55km = 550m
Release Height = 4300ft (1311m)
Landing Elevation = 900 ft (274m)
LOH = 1037m which is more than 550m so the claim is invalid.
