2. Craft fitted with an automatic stabilization system are to be provided with an automatic safety con- trol unless redundancy in the system provides equivalent safety. Where an automatic safety control is fitted, provision is to be made to override it and to cancel the override from the main control position.

3. The parameters and the levels at which any automatic safety control is to give the command to de- crease speed and put the craft safely into the displacement or other safe mode are to be chosen with regard to the safe values of hill, trim, yaw and a combination of trim and draught appropriate to the particular craft and service such as the possible consequences of power failure for pro- pulsion, lift or stabilization devices.

4. The parameters and the degree of stabilization of the craft provided by the automatic stabilization system are to be chosen with due regard to the purpose and service conditions of the craft.
