Section 125.329

This paragraph does not apply to a person who has been given a briefing before a previous leg of a flight in the
same airplane.
(c) The oral briefing required by
paragraph (a) of this section shall be
given by the pilot in command or a
member of the crew. It shall be supplemented by printed cards for the use of
each passenger containing - 
(1) A diagram and method of operating the emergency exits; and
(2) Other instructions necessary for
the use of emergency equipment on
board the airplane.
Each card used under this paragraph
must be carried in the airplane in locations convenient for the use of each
passenger and must contain information that is appropriate to the airplane
on which it is to be used.
(d) The certificate holder shall describe in its manual the procedure to
be followed in the briefing required by
paragraph (a) of this section.
(e) If the airplane does not proceed
directly over water after takeoff, no
part of the briefing required by paragraph (a)(6) of this section has to be
given before takeoff but the briefing
required by paragraph (a)(6) must be
given before reaching the overwater
part of the flight.

Section 125.329 Minimum altitudes for use of
autopilot.
(a) Definitions. For purpose of this
section - 
(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 specifi-

cally in reference to DA (H) or MDA, in
which case the altitude is defined by
reference to the DA(H) or MDA itself.
(b) Takeoff and initial climb. No person
may use an autopilot for takeoff or initial climb below the higher of 500 feet
or an altitude that is no lower than
twice the altitude loss specified in the
Airplane Flight Manual (AFM), except
as follows - 
(1) At a minimum engagement altitude specified in the AFM; or
(2) At an altitude specified by the Administrator, whichever is greater.
(c) Enroute. No person may use an
autopilot enroute, including climb and
descent, below the following - 
(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) Approach. No person may use an
autopilot at an altitude lower than 50
feet below the DA(H) or MDA for the
instrument procedure being flown, except as follows - 
(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 Section 91.155 of this chapter;
(B) Suitable visual references specified in Section 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 altitude loss specified in
the AFM or 50 feet above the TDZE,
when the following conditions are
met - 
(A) Reported weather conditions are
equal to or better than the basic VFR
weather conditions in Section 91.155 of this
chapter; and
