§29.1329 Automatic pilot system

(a) Each automatic pilot system m ust b e designed so that the automatic pilot can: (1) Be sufficiently overpowered by one pilot to allow control of the rotorcraft; and (2) Be readily an d p ositively disengaged by each pilo t to prevent it from interfering with the control of the rotorcraft. (b) Unless there is automatic synchronisation, each system must have a means to readily indicate to th e p ilot th e alig nment of the actuating device in relation to the control system it operates. (c) Each m anually operated control for the system’s operation m ust be readily accessible to the pilots. (d) The sy stem m ust be designed and adjusted so th at, with in the range of adjust ment available to the pilot, it cannot produce hazardous loads on the rotorcraft, or create hazardous deviations i n t he fl ight pat h, under any fl ight condition appropriate t o i ts use, ei ther duri ng normal operation or i n the event of a m alfunction, assuming that corrective action begins within a reasonable period of time. (e) If the au tomatic p ilot in tegrates sig nals from au xiliary co ntrols o r fu rnishes sig nals fo r operation of ot her equi pment, t here must be positive interlocks and seq uencing o f en gagement to prevent improper operation. (f) If the automatic pilot system can be coupled to ai rborne navi gation equi pment, m eans must be provided to indicate to the pilots the current mode of operation. Selector switc h position is not acceptable as a means of indication.
