Rule of thumb fudge factor
With experience you can evaluate the conditions of the day and adjust
accordingly. If winds are light and lift is good you can use 2000ft margin to arrive at the next landable location. Even on a good day I use 85% of the L/D plus a safety margin. If you examine the flights of experienced pilots they at time appear to take much larger risks but it is because they can judge the conditions and anticipate changes that they are able to do this successfully. Be careful at first as you can get into trouble fast especially on days where the wind is blowing. wrote: Half.
