14 CFR Ch. I (1–1–19 Edition) 

§ 125.206 

(a) A vertical speed indicator; 
(b) A free-air temperature indicator; 
(c) A heated pitot tube for each air-

speed indicator; 

(d) A power failure warning device or 

vacuum indicator to show the power 
available for gyroscopic instruments 
from each power source; 

(e) An alternate source of static pres-

sure for the altimeter and the airspeed 
and vertical speed indicators; 

(f) At least two generators each of 

which is on a separate engine, or which 
any combination of one-half of the 
total number are rated sufficiently to 
supply the electrical loads of all re-
quired instruments and equipment nec-
essary for safe emergency operation of 
the airplane; and 

(g) Two independent sources of en-

ergy (with means of selecting either), 
of which at least one is an engine-driv-
en pump or generator, each of which is 
able to drive all gyroscopic instru-
ments and installed so that failure of 
one instrument or source does not 
interfere with the energy supply to the 
remaining instruments or the other en-
ergy source. For the purposes of this 
paragraph, each engine-driven source 
of energy must be on a different en-
gine. 

(h) For the purposes of paragraph (f) 

of this section, a continuous inflight 
electrical load includes one that draws 
current continuously during flight, 
such as radio equipment, electrically 
driven instruments, and lights, but 
does not include occasional intermit-
tent loads. 

(i) An airspeed indicating system 

with heated pitot tube or equivalent 
means for preventing malfunctioning 
due to icing. 

(j) A sensitive altimeter. 
(k) Instrument lights providing 

enough light to make each required in-
strument, switch, or similar instru-
ment easily readable and installed so 
that the direct rays are shielded from 
the flight crewmembers’ eyes and that 
no objectionable reflections are visible 
to them. There must be a means of con-
trolling the intensity of illumination 
unless it is shown that nondimming in-
strument lights are satisfactory. 

§ 125.206

Pitot heat indication systems. 

(a) Except as provided in paragraph 

(b) of this section, after April 12, 1981, 
no person may operate a transport cat-
egory airplane equipped with a flight 
instrument pitot heating system unless 
the airplane is equipped with an oper-
able pitot heat indication system that 
complies with § 25.1326 of this chapter 
in effect on April 12, 1978. 

(b) A certificate holder may obtain 

an extension of the April 12, 1981, com-
pliance date specified in paragraph (a) 
of this section, but not beyond April 12, 
1983, from the Executive Director, 
Flight Standards Service if the certifi-
cate holder— 

(1) Shows that due to circumstances 

beyond its control it cannot comply by 
the specified compliance date; and 

(2) Submits by the specified compli-

ance date a schedule for compliance ac-
ceptable to the Executive Director, in-
dicating that compliance will be 
achieved at the earliest practicable 
date.

§ 125.207

Emergency equipment re-

quirements. 

(a) No person may operate an air-

plane having a seating capacity of 20 or 
more passengers unless it is equipped

ment: 

(1) One approved first aid kit for 

treatment of injuries likely to occur in 
flight or in a minor accident, which 
meets the following specifications and 
requirements: 

(i) Each first aid kit must be dust 

and moisture proof and contain only 
materials that either meet Federal 
Specifications GGK–391a, as revised, or 
as approved by the Administrator. 

(ii) Required first aid kits must be 

readily accessible to the cabin flight 
attendants. 

(iii) Except as provided in paragraph 

(a)(1)(iv) of this section, at time of 
takeoff, each first aid kit must contain 
at least the following or other contents
