• ED Decision 2003/13/RM found in: Sailplane Rule Book - Part-SAO Part-SFCL CS-22 (Nov 2022)

AMC 22.447(a) Combined loads on tail surfaces ED Decision 2003/13/RM (1) In the absence of rational data the unsymmetrical distribution shall be obtained by multiplying the air load on one side of the plane of symmetry by (1+x) and on the other side by (1-x). (2) For point A of the V-n envelope the value of x shall be 0.34 and in the case of an aerobatic category sailplane certificated for flick manoeuvres x shall be 0.5. For point D the value of x shall be 0.15. (3) The unsymmetrical horizontal tail load must not be combined with the induced rolling moment at the T-tail.
