• ED Decision 2003/18/RM found in: CS-VLA Amdt 1 - Very Light Aeroplanes (Mar 2009)

CS-VLA 181 Dynamic stability ED Decision 2003/18/RM (a) Any short period oscillation not including combined lateral-directional oscillations occurring between the stalling speed and the maximum allowable speed appropriate to the configuration of the aeroplane must be 'heavily damped with the primary controls - (1) Free; and (2) In a fixed position (b) Any combined lateral-directional oscillations ('Dutch roll') occurring between the stalling speed and the maximum allowable speed appropriate to the configuration of the aeroplane must be damped to 1/10 amplitude in 7 cycles with the primary controls - (1) Free; and (2) In a fixed position.
