AMC No. 1 to CS 25.143(g) Controllability and Manoeuvrability

An acceptable means of compliance with the requirement that stick forces may not be excessive when manoeuvring the aeroplane, is to demonstrate that, in a turn for 0·5g incremental normal acceleration (0·3g above 6096 m (20 000 ft)) at speeds up to VFC/MFC, the average stick force gradient does not exceed 534 N (120 lbf)/g.
