Calculation of all-up flying weight

All-up flying weight is the weight of the Pilot plus all the equipment including the glider. The best way to find it is to stand on the scales dressed in all your flying clothing, boots etc. and carrying your glider bag with all the equipment you take flying with you. If this is not possible, you can obtain a rough approximation by adding 15 to 20 kg to your bodyweight - 20 kg if your equipment is heavy, including reserve, back protection etc.; 15 kg if you have relatively lightweight equipment. To calculate your bodyweight in kg if you know it in stones and pounds:

Multiply number of stones by 14 and add on the number of pounds. This gives your weight in pounds (eg. 10 stone 9 pounds: 10 x 14 = 140 add on 9 = 149 pounds). Now multiply this figure by 0.454 to give bodyweight in kg ( e.g. 149 x 0.454 = 68kg to the nearest whole number of kg).

From this figure, add on 15 or 20 kg to estimate all-up weight, i.e. a pilot who weighs 10 stone 9 pounds will have an all up weight of between 83 and 88 kg, depending on equipment.
