AMC 25.21(d) Proof of compliance ED Decision 2003/2/RM 1 Where variation of the parameter on which a tolerance is permitted will have an appreciable effect on the test, the result should be corrected to the specified value of the parameter; otherwise no correction is necessary. 2 In areas of critical handling or stability, notwithstanding the tolerance of [CS 25.21(d)](#_DxCrossRefBm1709820660) (7% total travel), aft centre of gravity tests should be flown at a centre of gravity not more forward than the certificate aft centre of gravity limit. Tests which are critical on the forward centre of gravity limit should be flown at centres of gravity at least as forward as the certificate forward limit.
