(a) (1) Altitudes for takeoff/initial climb and go-around/missed approach are defined as above the airport elevation. (2) Altitudes for enroute operations are defined as above terrain elevation. (3) Altitudes for approach are defined as above the touchdown zone elevation (TDZE), unless the altitude is specifically in reference to DA (H) or MDA, in which case the altitude is defined by reference to the DA(H) or MDA itself. (b) (1) At a minimum engagement altitude specified in the AFM; or (2) At an altitude specified by the Administrator, whichever is greater. (c) (1) 500 feet; (2) At an altitude that is no lower than twice the altitude loss specified in the AFM for an autopilot malfunction in cruise conditions; or (3) At an altitude specified by the Administrator, whichever is greater. (d) (1) For autopilots with an AFM specified altitude loss for approach operations— (i) An altitude no lower than twice the specified altitude loss if higher than 50 feet below the MDA or DA(H); (ii) An altitude no lower than 50 feet higher than the altitude loss specified in the AFM, when the following conditions are met— (A) Reported weather conditions are less than the basic VFR weather conditions in § 91.155 of this chapter; (B) Suitable visual references specified in § 91.175 of this chapter have been established on the instrument approach procedure; and (C) The autopilot is coupled and receiving both lateral and vertical path references; (iii) An altitude no lower than the higher of the al
