A IGC security checking software IGC Shell with the proper DLL is used to detect innocent flaws which can corrupt a data file during download.
You are required to submit the calibration certificate for all Diamond Badges and FAI Diplomas.
It is recommended to give it a few minutes to give a post-flight baseline before switching off.
Only FAI approved flight recorders may be used. A PR approval can be applied for at IGC, see SC3#2.5.
Please visit the FAI website for further details; https://www.fai.org/page/igc-approved-flight-recorders Also make sure the FR you have selected has the correct approval level for the specific badge, diploma, or record.
Yes, but all FR(s) selected by the pilot require to be noted and inspected before take-off. All FR(s) that are selected must have identical declarations.
Yes, the barometric recording function of a FR shall be calibrated within 5 years prior to the flight or within 2 months after the flight.
A FR is not 100% accurate throughout the entire altitude range. They are therefore tested and pressure calibrated to measure the instruments error.
If the FR calibration period has lapsed, GPS height data may be used for Silver, Gold and National Diploma claims, provided that a 100mtr error margin is applied (example: the gain of height is at least 1100 metres for Silver altitude). This concession is not applicable to FAI Distance Diplomas or Diamond badges
Yes, except for the Silver Duration if the entire flight is performed under continual attention of the “OO” from take-off to landing.
