This paragraph does not apply to a per-
son who has been given a briefing be-
fore 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 supple-
mented by printed cards for the use of 
each passenger containing— 

(1) A diagram and method of oper-

ating 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 loca-
tions convenient for the use of each 
passenger and must contain informa-
tion that is appropriate to the airplane 
on which it is to be used. 

(d) The certificate holder shall de-

scribe 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 para-
graph (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.

§ 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 de-
fined 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 ini-
tial 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 alti-

tude specified in the AFM; or 

(2) At an altitude specified by the Ad-

ministrator, 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 Ad-

ministrator, 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, ex-
cept as follows— 

(1) For autopilots with an AFM speci-

fied altitude loss for approach oper-
ations— 

(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 condi-
tions are met— 

(A) Reported weather conditions are 

less than the basic VFR weather condi-
tions in § 91.155 of this chapter; 

(B) Suitable visual references speci-

fied in § 91.175 of this chapter have been 
established on the instrument ap-
proach procedure; and 

(C) The autopilot is coupled and re-

ceiving 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 § 91.155 of this 
chapter; and
