AMC 22.23 Load distribution limits ED Decision 2003/13/RM Significant variations of lateral c.g. are only likely to occur on sailplanes equipped for the carriage of expendable ballast in the wings. Such variations may result from any permitted intentional asymmetric loading or from levels of asymmetric loading which might realistically be expected to occur unintentionally, particularly if flight is permitted with partly-filled tanks. In this case, the range of lateral c.g. considered should not be less than the greater of:- (1) Any intentional asymmetric loading that is permitted; and (2) The level of asymmetry that might realistically be expected to occur inadvertently, taking account of the design of the system and the likely accuracy of loading. In the absence of a more rational analysis to establish any greater or lesser value, an asymmetry of 10 litres, or 10% of the combined capacity of each symmetrical pair of tanks, whichever is the greater, may be assumed.
