Section 125.206

14 CFR Ch. I (1-1-19 Edition)

(a) A vertical speed indicator;
(b) A free-air temperature indicator;
(c) A heated pitot tube for each airspeed 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 pressure 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 required instruments and equipment necessary for safe emergency operation of
the airplane; and
(g) Two independent sources of energy (with means of selecting either),
of which at least one is an engine-driven pump or generator, each of which is
able to drive all gyroscopic instruments and installed so that failure of
one instrument or source does not
interfere with the energy supply to the
remaining instruments or the other energy source. For the purposes of this
paragraph, each engine-driven source
of energy must be on a different engine.
(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 intermittent 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 instrument, switch, or similar instrument 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 controlling the intensity of illumination
unless it is shown that nondimming instrument lights are satisfactory.

Section 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 category airplane equipped with a flight
instrument pitot heating system unless
the airplane is equipped with an operable pitot heat indication system that
complies with Section 25.1326 of this chapter
in effect on April 12, 1978.
(b) A certificate holder may obtain
an extension of the April 12, 1981, compliance date specified in paragraph (a)
of this section, but not beyond April 12,
1983, from the Executive Director,
Flight Standards Service if the certificate holder - 
(1) Shows that due to circumstances
beyond its control it cannot comply by
the specified compliance date; and
(2) Submits by the specified compliance date a schedule for compliance acceptable to the Executive Director, indicating that compliance will be
achieved at the earliest practicable
date.
