No margin is allowed – exceeding 1% invalidates the flight. Be especially aware of this when the finish point or the possibility of landing is at a lower altitude than the start. A Silver badge distance flight that is exactly 50 km can have a loss of height from start to finish of no more than 500 metres. A 60 km flight is allowed 600 metres and so on up to a 100 km flight. For pilots using altimeters that display altitude in feet, Table A below will be of assistance in determining the maximum height loss for these short flights.

However, to be cautious, you should use a start height that will allow a valid claim even if you landed just after the 50 kilometre leg was flown. Remember that you can select a position fix in the flight recorder data as a “remote” finish. See paragraph 4.4. If you plan to use such a finish, take care that the 1% rule is not broken. 2.2 Height penalty – for distance flights over 100 km (SC3-4.4.3a) For flights greater than 100 km, there is a penalty on the claimed distance if the loss of height exceeds 1000m so that there can be no benefit to deliberately starting a task with excess height. This penalty, now 100 times the excess height loss, has increased over time to keep pace with the increasing performance of gliders. If a loss of height is 1257 metres, for example, then the distance flown is reduced by 100 times 257 metres or 25.7 kilometres. 5 ore durata dallo sgancio m 1000 guadagno quota 1000 Km 300 distanza in linea retta A _______ B Triangolo di distanza totale Km 300 B A Quota max sgancio m 1000 C Km 300 a farfalla B - Assisi D - Trevi A - Cittaducale C - Borgo San Pietro - Triangolo di distanza totale Km 300 B A Quota max sgancio m 1000 C Km 500 linea retta andata e ritorno a farfalla B D A C A _____________ B A _______ B NORMATIVA Franca - CODICE FAI Section 3 Section 3c
